Mediterranean Theater

Lead

The Mediterranean Theater was one of the longest-running theaters of the Second World War, lasting from Italy’s declaration of war on 10 June 1940 until the surrender of German forces in Italy on 2 May 1945. It covered the Mediterranean Sea and its shores, from Gibraltar in the west to the Levant in the east, and from the deserts of Libya and Egypt in the south to the mountains of Greece and Italy in the north.

The theater also included the Middle East and East Africa, where British and Commonwealth forces fought Italian armies in 1940 and 1941. Because the war here was fought across sea, desert and mountain, it tested every part of a modern military machine: navies, air forces, supply convoys, and armies that had to be fed and fuelled across enormous distances.

The strategic prize was control of the Mediterranean itself. For Britain, the sea was the short route to India, to the oil of the Middle East, and to the Suez Canal, the artery through which the British Empire supplied itself.

For Italy, the Mediterranean was Mare Nostrum — “our sea” — and Benito Mussolini entered the war expecting a short conflict in which Italy would seize Egypt, the Suez Canal, Malta and Greece, and turn the sea into an Italian lake.

For Germany, the Mediterranean was at first a sideshow, a place to rescue a failing Italian ally; by 1943 it had become a second front that drew in German divisions, aircraft and fuel the Reich could not spare from the Eastern Front (World War II).

The theater unfolded in a series of connected campaigns rather than as a single battle. Italian armies were defeated in East Africa and in the Libyan desert in 1940 and 1941. German forces under Erwin Rommel then turned the desert war into a two-year seesaw that ran from Tobruk to El Alamein and back again.

Malta, a small island fortress, was besieged for more than two years and became the most bombed place in the war. Greece and Crete fell to German invasion in the spring of 1941. In November 1942 the Allies landed in French North Africa in Operation Torch, and by May 1943 the Axis had been driven out of Africa altogether.

The war then moved to Sicily and to mainland Italy, where a hard mountain campaign lasted until the final days of the war in Europe.

No single battle decided the Mediterranean Theater. Its importance lay in what it cost the Axis and what it taught the Allies. The desert war destroyed the Italian army as a fighting force and consumed German tanks, aircraft and fuel. The Italian campaign tied down more than twenty German divisions in 1944 and 1945 that might otherwise have fought in France or on the Eastern Front.

And the amphibious landings in North Africa, Sicily, Salerno and Anzio gave the Western Allies the experience in large-scale combined operations that made the invasion of Normandy possible. This article gives the full overview of the theater: its strategy, its commanders, its logistics, its phases and its results.

The campaigns within it are summarized here and covered in detail in their own articles, above all the North Africa Campaign and the Italian Campaign (World War II).

Background

Italy Enters the War

Italy declared war on Britain and France on 10 June 1940, the day after German armies reached the English Channel and a week before France asked for an armistice. Mussolini believed the war was nearly over and that Italy could claim its share of the spoils at little cost.

The Italian armed forces were large on paper — more than a million men under arms — but they were poorly equipped, short of motor transport, fuel and modern tanks, and led by officers chosen as much for loyalty as for ability. The Italian navy was powerful, with modern battleships and cruisers, but it lacked aircraft carriers and radar, and it was short of fuel oil.

The Italian air force had brave pilots but ageing aircraft. Mussolini’s ambitions were far larger than his means: he wanted Egypt and the Suez Canal, Malta, Greece, Yugoslavia, and a new Roman Empire around the Mediterranean.

Britain, by contrast, entered the Mediterranean war from a position of weakness that slowly turned into strength. In June 1940 Britain stood alone against Germany and Italy, its army had just been evacuated from Dunkirk, and its Mediterranean Fleet was based at Alexandria and Gibraltar.

But Britain held the two ends of the sea — Gibraltar in the west and the Suez Canal in the east — and it held Malta in the middle. It also had the resources of the Empire: troops from India, Australia, New Zealand, South Africa and Canada, and, from late 1941, the growing industrial power of the United States.

The Mediterranean war became a contest of logistics as much as of battles, and in logistics the Allies grew steadily stronger while the Axis grew steadily weaker.

Why the Mediterranean Mattered

The Mediterranean mattered for three reasons, and each of them shaped the fighting. The first was the Suez Canal. The canal was the short route between Britain and India, Australia and the oil of the Persian Gulf. If the Axis had taken it, British ships would have had to sail around Africa, adding thousands of miles and weeks to every voyage, and the Middle Eastern oilfields would have been within Axis reach. The defense of Egypt and the canal was therefore Britain’s first priority in the theater, and the desert war in Libya and Egypt was fought, in the end, to keep the canal out of Axis hands.

The second reason was shipping. The Mediterranean was a narrow sea crossed by short convoy routes, and whoever controlled its airfields and ports could strangle the other’s supply lines. Malta sat astride the Axis supply route from Italy to Libya, and British aircraft and submarines based on the island sank a large share of the fuel, tanks and food Rommel needed. Axis aircraft based in Sicily did the same to British convoys trying to resupply Malta, and the island came close to starvation in 1942. The naval and air war over the convoys was as important as any land battle, and it was fought every week for nearly three years.

The third reason was political. The Mediterranean was where the Western Allies could fight Germany on land before they were ready to invade France. The campaigns in North Africa, Sicily and Italy kept pressure on Germany, knocked Italy out of the war, forced Germany to defend a long southern front, and gave American and British troops their first experience of fighting the German army. That experience was bought at a high price in Italy, where the campaign became a long and costly grind through mountain after mountain.

The Middle East and East Africa

The theater began not in Europe but in Africa. In August 1940 Italian forces from Italian East Africa invaded British Somaliland, and in September the Italian Tenth Army in Libya invaded Egypt, advancing about 60 miles to Sidi Barrani before stopping to build fortified camps.

In East Africa the Italians had some 200,000 men, a large force on paper, but they were isolated, short of supplies, and spread across Ethiopia, Eritrea and Somaliland. British and Commonwealth forces, with Ethiopian patriots, attacked from Sudan and Kenya in early 1941, and the East African campaign was over by November 1941, when the last Italian stronghold at Gondar surrendered.

The campaign is often overlooked, but it removed the Italian threat to the Red Sea route to Suez and freed British troops for the desert war. It is summarized here because it belonged to the same theater; the detailed fighting in East Africa is covered in the campaign histories linked from the sources below.

Opposing Forces

The Axis Powers

The Axis in the Mediterranean was an unequal partnership. Italy supplied most of the troops in 1940 and 1941 — large infantry armies in Libya and East Africa, a strong navy, and an air force — but Italian industry could not replace losses in tanks, trucks and aircraft at the rate the war demanded.

Germany supplied the quality that Italy lacked: the Afrika Korps under Rommel, with modern tanks, anti-tank guns and a doctrine of fast mobile warfare; the Luftwaffe, whose bombers and fighters dominated the central Mediterranean in 1941 and 1942; and, from 1943, Field Marshal Albert Kesselring, one of Germany’s most able defensive commanders, who held Italy for twenty months against superior Allied numbers.

German and Italian forces never fully integrated their commands, and the two allies disagreed repeatedly about strategy — most famously over whether to take Malta, an operation the Germans planned and then cancelled.

Axis logistics were the theater’s central weakness. Every tank, litre of fuel and crate of ammunition for the desert army had to cross the Mediterranean from Italy, past Malta, in ships that British submarines, aircraft and surface ships hunted constantly. In some months in 1942, less than half of the supplies dispatched from Italy reached Libya. Rommel’s army was often short of fuel at the very moment it needed to advance, and the shortage grew worse as the war went on. In Italy, by contrast, the Germans fought on interior lines over short distances, with the advantage of mountainous ground, and their supply problem was far less severe — one reason the Italian campaign lasted so long.

The Allies

The Allied forces in the Mediterranean were a coalition, and that was both their strength and their difficulty. The British Eighth Army, which fought the desert war, was built from British, Australian, New Zealand, South African, Indian and Polish troops, with Free French forces as well. Its commanders changed repeatedly — Wavell, Auchinleck, then Montgomery — as London searched for a general who could beat Rommel.

The Americans arrived in force in November 1942 with Operation Torch, bringing fresh divisions, tanks and aircraft, and an American supreme commander, Eisenhower, whose job was to hold a fractious coalition together. By 1944 the Allied armies in Italy included British, American, French, Polish, Canadian, Indian, New Zealand, South African, Brazilian and Italian co-belligerent troops.

Allied strength grew with time. In 1940 Britain fought with what it had. By 1942 American factories were supplying Sherman tanks, trucks and aircraft in numbers the Axis could not match. By 1943 the Allies had air supremacy over the Mediterranean, and their navies could move troops and supplies almost at will. The price of coalition warfare was friction: British and American commanders disagreed about strategy, about whether to invade Sicily or Sardinia, about how far to advance in Italy, and about the value of the Italian campaign itself. Eisenhower’s and later Alexander’s skill in managing those disagreements was as important to the Allied victory as any battle.

Sea and Air Power

The Mediterranean was a naval and air theater before it was a land theater. The British Mediterranean Fleet under Admiral Andrew Cunningham fought the Italian navy in a series of actions — Taranto in November 1940, when carrier aircraft crippled three Italian battleships in harbour; Cape Matapan in March 1941, when three Italian heavy cruisers were sunk; and the long convoy battles around Malta.

The Italian navy, though it fought bravely in individual actions, was hampered by a shortage of fuel and by the absence of air cover, and after 1941 it rarely left port. German U-boats in the Mediterranean sank valuable British ships, including the aircraft carrier Ark Royal and the battleship Barham, but they could not change the balance of sea power.

Air power was decisive in a different way. The Luftwaffe’s Fliegerkorps X, based in Sicily, nearly strangled Malta in 1941 and 1942, and German bombers sank British cruisers and destroyers at a rate the Royal Navy could barely sustain. But the balance shifted in 1942 and 1943 as Allied air forces grew: the Desert Air Force supported Montgomery’s advance, American heavy bombers struck Italian ports and Romanian oilfields from bases in North Africa, and by the time of the Sicily landings the Allies had overwhelming air superiority. Control of the air meant control of supply, and control of supply decided the desert war.

The Mediterranean, 1940–1945

The First Year: East Africa, Greece and Crete

The first year of the theater belonged to Britain, and then to Germany. In December 1940 General Wavell’s Western Desert Force launched Operation Compass against the Italian Tenth Army in Egypt. In two months of fast-moving desert warfare, a force of about 30,000 men destroyed an Italian army of more than 150,000, taking some 130,000 prisoners and advancing 500 miles to El Agheila in Libya. It was a stunning victory, and it was undone almost at once: Wavell’s best divisions were sent to Greece in early 1941 to meet a threatened German invasion, and the desert force was left thin just as Rommel arrived in Tripoli with the first units of the Afrika Korps.

Greece proved a disaster. Mussolini had invaded Greece from Albania in October 1940 without telling Hitler, and the Greek army had driven the Italians back. In April 1941 Germany intervened, invading Yugoslavia and Greece, and the British expeditionary force was evacuated from the Greek mainland with heavy losses.

In May 1941 German paratroops seized Crete in the first large-scale airborne invasion in history, at a cost of so many paratroops that Hitler never again attempted an operation on that scale. The Battle of Crete is covered in its own article. By June 1941 the Axis held the Balkans, Greece and Crete, and Britain’s position in the eastern Mediterranean was reduced to Egypt and Cyprus.

The theater’s first phase had ended with the Axis in command of the northern shore.

The Desert War in Outline

The desert war, fought between June 1940 and May 1943, was the theater’s central land campaign, and it is told in full in the North Africa Campaign article. Only the outline belongs here. Rommel’s arrival in February 1941 turned the desert war into a two-year seesaw: he drove the British back to Tobruk and the Egyptian frontier in the spring of 1941, was driven back to El Agheila by Operation Crusader at the end of the year, advanced again in 1942 to Gazala and Tobruk, and reached El Alamein, only 60 miles from Alexandria, in July 1942.

There the British stopped him. At the Second Battle of El Alamein in October and November 1942, Montgomery’s Eighth Army broke the Axis line, and Rommel retreated 1,400 miles across Libya to Tunisia. The campaign ended in May 1943 when the remaining Axis forces in Tunisia surrendered — some 250,000 men — and North Africa passed entirely into Allied hands.

The desert war’s importance to the whole theater was that it destroyed the Italian army in Africa, wore down the Afrika Korps, and gave the Allies the bases from which to invade Sicily and Italy.

Malta and the War at Sea

Malta was the hinge of the Mediterranean war. The island lay 60 miles south of Sicily, directly across the Axis supply route to Libya, and from it British submarines, aircraft and surface ships sank Axis supply vessels throughout 1941 and 1942. The Axis answered with a siege: German and Italian bombers attacked Malta almost daily, and the island endured more than 3,000 air raids.

By the spring of 1942 Malta was running out of food, fuel and ammunition, and its air defenses were nearly exhausted. Convoys from Gibraltar and Alexandria fought through at terrible cost — the most famous, Operation Pedestal in August 1942, lost nine of fourteen merchant ships but brought the tanker Ohio, crippled and towed into harbour, with enough fuel to keep Malta fighting.

The Siege of Malta is covered in its own article. The siege ended in late 1942 as Allied air power grew and Rommel’s retreat removed the immediate threat. Malta’s survival mattered because it kept the Axis supply line under attack for the whole of the desert war; historians estimate that a large share of the supplies Rommel needed never reached him, in part because of Malta.

Torch, Tunisia and the End in Africa

In November 1942 the Allies opened a second front in North Africa. Operation Torch landed American and British forces in Morocco and Algeria, under Eisenhower’s command, with the aim of striking Rommel’s army from the west while Montgomery pursued it from the east.

The landings met resistance from Vichy French forces for a few days, then the French joined the Allies, and the campaign moved into Tunisia, where Germany rushed reinforcements by air and sea. The fighting in Tunisia lasted six months, through the winter rains and the mountains of the Dorsale, and included the American defeat at Kasserine Pass in February 1943 — a sharp lesson in fighting the German army — and the final Allied offensive in April and May.

On 13 May 1943 the last Axis forces in Tunisia surrendered. The Allies had won North Africa, and they held the southern shore of the Mediterranean from Morocco to Egypt. The next step was obvious: the invasion of Europe would begin across the narrow sea, in Sicily.

Sicily and Italy in Outline

Operation Husky, the July 1943 invasion of Sicily, was the biggest seaborne landing attempted up to that point in the war, and the island was secured within five weeks. Mussolini was removed from power on 25 July, and Italy signed an armistice on 8 September. Berlin answered immediately: German troops stripped Italian units of their weapons, seized the north and centre of the country, and made Italy itself the battlefield.

The September 1943 landings at Salerno came close to disaster, and after them the Allied push north ran into the Winter Line. Fighting around Monte Cassino and the Anzio beachhead filled the winter of 1943–1944. Rome was liberated on 4 June 1944, only two days ahead of D-Day, yet the campaign dragged on — through the Gothic Line and another hard winter — until the Germans in Italy laid down their arms on 2 May 1945.

The full story is told in the Italian Campaign (World War II) article. For the theater as a whole, the Italian campaign’s significance was that it knocked Italy out of the war, tied down German divisions, and opened the Mediterranean to Allied shipping — though it never produced the rapid advance its planners had hoped for, and it became the longest and most grinding campaign the Western Allies fought in Europe.

Turning Point

El Alamein and Torch

The turning point of the Mediterranean Theater came in the autumn of 1942, in two events that arrived within weeks of each other. The first was the Second Battle of El Alamein, which opened on 23 October and ended on 11 November 1942.

Montgomery’s Eighth Army, with more than 200,000 men, over 1,000 tanks and overwhelming air support, attacked Rommel’s Panzer Army Africa, which had about 100,000 men, some 500 tanks, and was desperately short of fuel — at one point Rommel had only enough petrol for a few days of operations. The battle was a set-piece infantry and artillery offensive, fought through minefields, and it broke the Axis line after twelve days.

Rommel retreated, and for the first time in the desert war the retreat did not stop: the Eighth Army pursued him across Libya to Tunisia. After El Alamein, Egypt and the Suez Canal were safe from Axis attack for good, and Britain could at last claim an unambiguous battlefield triumph over the German army on land.

The second event was Operation Torch, the Allied landings in Morocco and Algeria on 8 November 1942. Torch placed a second Allied army in Rommel’s rear and made the Axis position in Africa untenable. It also brought the United States into the Mediterranean ground war in strength, and it gave Eisenhower, the Allied commander, his first experience of commanding a coalition in battle.

Together, El Alamein and Torch meant that the Axis could no longer win in Africa; the only question was how long it would take to lose. Churchill called El Alamein “the end of the beginning,” and for the Mediterranean that was exactly right: after the autumn of 1942, the Allies were on the offensive for the rest of the war.

Why Sicily Confirmed the Turn

If El Alamein and Torch were the turning point, the invasion of Sicily in July 1943 confirmed it. Husky showed that the Allies could mount a large amphibious operation against defended shores, that they had command of the sea and the air, and that the Axis could not reinforce fast enough to stop them.

The fall of Mussolini during the Sicily campaign showed that the turn was political as well as military: Italy, the junior Axis partner, was leaving the war. From Sicily onward, Germany fought in the Mediterranean on the defensive, trading ground for time — first in Sicily, then in Italy — and the initiative never returned to the Axis.

The theater’s character changed accordingly: the open desert war of manoeuvre gave way to the slow mountain war of Italy, and the Mediterranean became a place where Germany spent divisions it needed elsewhere.

Gibraltar in World War II

Gibraltar was the western gate of the Mediterranean, and throughout the war it was one of the most strategically important places in the theater. The Rock, a British fortress and naval base at the southern tip of Spain, guarded the Strait of Gibraltar, the only entrance to the Mediterranean from the Atlantic.

Whoever held Gibraltar controlled the passage of ships in and out of the sea, and Britain held it throughout the war. The base served as the headquarters of Force H, the naval squadron that escorted convoys to Malta and protected the western Mediterranean, and it was the assembly point for the convoys of Operation Torch in November 1942, when hundreds of ships gathered off Gibraltar before sailing for North Africa.

Gibraltar’s value made it a target, and the Axis made repeated efforts to neutralize it. The German plan to seize the Rock, Operation Felix, was drawn up in 1940 and called for German troops to cross Spain and attack Gibraltar from the landward side.

It never happened, because the Spanish dictator Francisco Franco refused to allow German troops through Spain, and Hitler was unwilling to force the issue while he was preparing the invasion of the Soviet Union. Franco’s refusal was one of the most consequential decisions of the Mediterranean war: had Germany taken Gibraltar, the western Mediterranean would have been closed to the Allies, Malta would have been impossible to supply from the west, and the Torch landings would have been far harder.

Instead, Gibraltar remained British, and Spain remained neutral, though Franco’s government was sympathetic to the Axis.

The Axis tried other means. Vichy French bombers attacked Gibraltar in July 1940 in retaliation for the British attack on the French fleet at Mers-el-Kebir, causing damage but not closing the base. Italian aircraft bombed the Rock intermittently. The most successful attacks came from the sea: Italian frogmen of the Decima Flottiglia MAS, riding human torpedoes, penetrated Gibraltar harbour in December 1941 and severely damaged two British battleships, and they returned in 1942 and 1943 to sink or damage merchant ships. German agents and saboteurs operated in the area, and the Abwehr maintained a watch on shipping movements from across the strait in Spanish Morocco. None of these efforts closed the base.

Gibraltar’s role grew as the war went on. It was the base from which the Pedestal convoy sailed to Malta in August 1942, the staging point for Torch, and a key airfield and naval base for the rest of the war.

The Rock also held a secret: Operation Tracer, a plan to seal a team of observers inside a hidden chamber in the Rock, where they would report on enemy shipping if Gibraltar fell. The chamber was built and provisioned, but it was never used, because Gibraltar never fell.

After the war, Gibraltar remained British, and its wartime record — a fortress that was bombed, attacked by frogmen, spied upon and threatened with invasion, but never taken — became a symbol of the Mediterranean war’s character: a war of bases, straits and supply lines, in which holding the right piece of ground mattered as much as winning a battle.

Casualties and Losses

Casualty figures for the Mediterranean Theater as a whole are uncertain, because the theater covered five years of fighting across three continents, and because the records of the Italian armed forces in particular are incomplete. No single reliable total exists, and the figures below are therefore given as ranges drawn from the campaign histories. What is certain is the scale: the theater cost hundreds of thousands of lives, and its largest single losses were suffered in North Africa, in Sicily and in Italy.

In North Africa, Allied casualties — killed, wounded, missing and captured — are estimated to range from about 200,000 to about 250,000 men across the whole campaign from 1940 to 1943. Axis losses in North Africa were far heavier, and estimates range from about 550,000 to about 950,000, a wide range that reflects the uncertainty over Italian losses and over how many Axis troops were taken prisoner.

The best-documented figure is the end of the campaign: about 250,000 Axis soldiers, German and Italian, surrendered in Tunisia in May 1943, the largest Axis surrender of the war before Stalingrad’s aftermath was fully counted. Italian losses in East Africa in 1940 and 1941 added tens of thousands more prisoners — some 130,000 Italians were captured in Operation Compass alone.

In Italy, the fighting of 1943–1945 was the most expensive part of the whole theater in lives. For the Allies, the Italian campaign’s toll of killed, wounded and missing is put at about 300,000 to about 330,000. German losses on the same ground are put at about 330,000 to about 440,000.

Between about 60,000 and about 150,000 Italian civilians died during the campaign, a toll driven by the bombing of Italian cities, combat passing through towns and villages, and German reprisals against civilians and partisans. The naval and air war added its own toll: the Royal Navy lost ships and men in the Malta convoys, the merchant navies lost thousands of sailors, and Malta’s civilian population endured more than 1,500 deaths from bombing.

The theater’s losses were not only military. Greece suffered a famine in the winter of 1941–1942 that killed tens of thousands, and Yugoslavia’s losses in the war that followed the 1941 invasion ran into the hundreds of thousands. These wider costs are part of the theater’s legacy, and they explain why the Mediterranean war is remembered in Greece, Italy and Yugoslavia not as a campaign of manoeuvre but as an occupation, a resistance and a liberation.

Map and Geography

A Narrow Sea

The Mediterranean is a long, narrow sea, about 2,300 miles from Gibraltar to the Levant, and rarely more than 500 miles wide. That geography shaped everything about the war. Armies fought along its shores because the sea was the fastest way to move men and supplies, and navies fought over it because whoever controlled the sea could move and the other could not.

The sea’s narrowness also meant that land-based aircraft could reach across it: bombers from Sicily could strike Malta and the convoys to it, bombers from North Africa could strike Sicily and southern Italy, and by 1943 Allied bombers from North Africa could reach the oilfields of Romania. In the Mediterranean, air power and sea power were inseparable.

The sea also set the tempo of the war: campaigns advanced as fast as ships could supply them, and they stopped when the ships stopped coming, which is why the desert war swung back and forth for two years instead of ending in a single decisive battle.

The Chokepoints

Three chokepoints governed the theater, and each of them was fought over. Gibraltar, at the western entrance, was held by Britain throughout the war. The Sicilian Channel, between Sicily and Tunisia, was the narrowest point of the central Mediterranean, and it was the killing ground of the convoy war: Axis aircraft from Sicily and British aircraft and submarines from Malta fought over it daily.

The Suez Canal, at the eastern end, was the prize the Axis never reached — Rommel’s furthest advance at El Alamein still left him some 200 miles from the canal. Control of the chokepoints meant control of movement, and the Allies held all three by the end of 1942.

The chokepoints also explain the shape of the whole theater: because the sea could be closed at either end and pinched in the middle, both sides fought the war as a struggle for passages and bases rather than for territory, and a single island fortress such as Malta could matter as much as an army.

Desert, Mountain and Island

The land fighting took place in three very different kinds of terrain, and each produced a different kind of war. The Libyan desert was open, flat and empty, ideal for fast-moving armoured warfare, where a tank force could advance a hundred miles in a day and where the decisive factor was not ground but fuel, water and supply.

The mountains of Greece, Yugoslavia and Italy produced the opposite kind of war: slow, infantry fighting through passes and river lines, where a single ridge could hold up an army for weeks, as Monte Cassino did in 1944. The islands — Malta, Crete, Sicily, Corsica, Sardinia — were fortresses and airfields, fought over by air and sea as much as by land.

The theater’s geography explains why no single doctrine or single commander could master it: the desert rewarded Rommel’s mobility, the mountains rewarded Kesselring’s defense, and the sea rewarded Cunningham’s fleet.

Outcome and Legacy of the Mediterranean Theater

The Mediterranean Theater ended in Allied victory. The Axis was driven from Africa, Italy left the war, and German forces in Italy surrendered on 2 May 1945, days before the end of the war in Europe. The Allies gained control of the Mediterranean, reopened the Suez route, and secured the southern flank of Europe.

For Britain, the victory secured the route to India and the Middle East oilfields that had been threatened since 1940. For the United States, the theater provided the first large-scale experience of coalition warfare and amphibious operations, and it proved that American and British forces could fight together.

For Italy, the outcome was a country divided, occupied and fought over for two years, and a monarchy and a regime that did not survive the war.

The theater’s military legacy is debated. Critics of the Italian campaign, including some American commanders, argued that it was a costly diversion that consumed divisions needed for the invasion of France, and that the resources spent in Italy would have been better used in Normandy.

Defenders argue that the campaign tied down more than twenty German divisions in 1944 and 1945, knocked Italy out of the war, forced Germany to defend the Balkans as well as Italy, and gave the Allies air bases in Italy from which they could bomb Germany and the Romanian oilfields. Both arguments have force, and historians still disagree about the balance.

What is not in doubt is that the Mediterranean campaigns destroyed the Italian armed forces, wore down the German army and air force, and kept the Western Allies fighting Germany on land for two years before D-Day.

The theater also left a political legacy. Greece and Yugoslavia emerged from occupation into civil war. Italy emerged as a republic, after a referendum in 1946 abolished the monarchy. The Middle East, where British and Free French forces had occupied Syria, Lebanon and Iraq during the war, moved toward independence in the years that followed. And the Mediterranean itself, which had been a British lake in 1939, became in the post-war years a sea divided between the Western alliance and the Soviet sphere — a division that would shape the Cold War. The war in the Mediterranean was, in that sense, the end of one era of the sea’s history and the beginning of another.

Commanders

Allied Commanders

The Mediterranean Theater had no single Allied commander for most of the war, and its command changed as the coalition grew. Archibald Wavell held the British Middle East command in 1940–1941, winning at Operation Compass and in East Africa, but the strain of simultaneous wars on several fronts wore him out, and Claude Auchinleck took his place.

Auchinleck directed the desert fighting across 1941 and 1942 and halted Rommel at the First Battle of El Alamein. Bernard Montgomery assumed command of the Eighth Army in August 1942, won the Second Battle of El Alamein — the theater’s best-known victory — and then chased Rommel across Libya. Dwight D.

Eisenhower commanded the Torch landings and the Allied forces in North Africa, and then the invasions of Sicily and Italy, before leaving for Normandy; his successor as Mediterranean commander, Henry Maitland Wilson, and the commander of Allied armies in Italy, Harold Alexander, saw the Italian campaign through to its end. Mark Clark commanded the American Fifth Army in Italy, landing at Salerno and taking Rome.

Among the naval commanders, Admiral Andrew Cunningham was the outstanding figure, winning the battles of Taranto and Matapan and keeping the Malta convoys running.

Axis Commanders

The Axis commanders were, for the most part, more stable in their posts than the Allies, and two of them dominated the theater. Erwin Rommel commanded the Afrika Korps and then the Panzer Army Africa from 1941 to 1943, and he remains the most famous general of the desert war: a bold, fast-moving commander whose offensives repeatedly surprised the British, but who also outran his supplies and was worn down by a war of logistics he could not win.

Albert Kesselring, in charge of the German forces in the Mediterranean from 1941 and of those in Italy from 1943, was the opposite of Rommel: a careful, defensive-minded commander who made Italy’s mountains and rivers into successive fortified lines and kept the Allies at bay for twenty months.

On the Italian side, Rodolfo Graziani commanded in Libya in 1940 and led the invasion of Egypt, Giovanni Messe led the Italian First Army in Tunisia in 1943 and fought ably through the campaign’s closing months, and Ugo Cavallero served as chief of the Italian general staff.

Mussolini himself intervened repeatedly in military decisions, usually to bad effect, and his political control of the war was one reason for Italy’s defeats.

The theater began with Italy’s declaration of war on 10 June 1940 and ended with the surrender of German forces in Italy on 2 May 1945. Some accounts start the fighting a day later, on 11 June, when the first air raids were flown, but 10 June 1940 is the standard opening date.

Why was the Mediterranean so important in World War II?

It held the Suez Canal, the short route between Britain and India and Middle Eastern oil, and it was the only place the Western Allies could fight Germany on land before the invasion of France in 1944. Control of the sea decided who could supply their armies.

What was the most important battle of the Mediterranean Theater?

Most historians name the Second Battle of El Alamein, fought in October and November 1942. After it, the Axis could no longer threaten Egypt or the Suez Canal, and Britain had its first unambiguous land victory over the German army.

Why did the Italian campaign last so long?

Germany’s commander, Albert Kesselring, used Italy’s mountains and rivers as a series of defensive lines, and the Allies had to fight through them one by one. The terrain favoured the defender, and the Allies were also short of troops after divisions were withdrawn for Normandy.

What role did Malta play in the war?

Malta sat across the Axis supply route from Italy to Libya, and British aircraft and submarines based there sank a large share of Rommel’s supplies. The island was besieged for more than two years and came close to starvation before convoys relieved it in 1942.

Did the Mediterranean campaigns help win the war?

They destroyed the Italian armed forces, tied down more than twenty German divisions in Italy in 1944 and 1945, knocked Italy out of the war, and gave the Allies the amphibious experience used at Normandy. Historians still debate whether Italy was worth the cost, but the campaigns kept Germany fighting on a second front for two years.
