Italy Falls to the Allies: February 1943-June 1943

By May 1943 more and more German U-Boat crew found antisubmarine warfare progressed. See more pictures of WWII.

By February 1943, momentum in the second World War seemed to have shifted somewhat. Yet critical Allied World War II victories on Guadalcanal and at Stalingrad have to be put into perspective. In both cases, the overwhelming bulk of enemy armed forces remained undefeated. In each instance, victory was geographically remote from the enemy heartland. The Allies understood that winning the war would be a long, drawn-out, and costly endeavor.

The turning points that are familiar to us now were less clear-cut at the time. In most cases, small victories were important in order to keep the Allied populations committed to an otherwise demoralizing and indecisive war. In February 1943, Adolf Hitler's propaganda minister, Joseph Goebbels, asked an audience in Berlin, "Do you want total war?" His audience clamored approval, but the mood among Nazi Germany's non-Nazi loyalists was somber and fearful. The changing expectations on both sides also played an important part in determining an outcome that was still more than two years away.



Just days before the German surrender at Stalingrad on January 31, 1943, President Franklin Roosevelt and Winston Churchill met for a high-level conference in the Moroccan city of Casablanca, recently captured in Operation Torch. There they discussed the future direction of the war. They gave the European Theater priority, but they would not commit to an invasion of Northern Europe until the Atlantic could be made safe for the mass transport of men and supplies. While the naval struggle continued, they agreed, the two Western states would capitalize on success in North Africa by continuing a Mediterranean strategy against Benito Mussolini's Italy. They would also maintain a relentless bombing campaign against the European Axis states to ease the pressure on the Red Army. This Combined Bomber Offensive was the Allies' substitute for a second front, which was deemed too risky in 1943.

At the final press briefing of the conference, President Franklin Roosevelt -- in agreement with Winston Churchill -- announced that the enemy states had only one option open to them: "unconditional surrender." Though secret contacts were occasionally made between individuals on both sides with a view to brokering an agreement, Roosevelt's public statement committed the Allies to a fight to the finish. No room was put aside for maneuver or compromise.

After a year in which the Allies lost 7.8 million tons of shipping, the submarine threat was expected to get worse during 1943. But a fortunate set of tactical changes tilted the balance in the Allies' favor. Most important was the adoption of new forms of radar on ships and aircraft as well as the transfer of adequate numbers of long-range planes to patrol the sea lanes. In May 1943, the German navy lost 41 submarines while Allied merchant vessel losses dropped sharply. Over the next two months, a further 54 submarines were sunk, prompting the German naval commander-in-chief, Admiral Karl Dönitz, to withdraw from the North Atlantic. The Allies' victory over the submarine menace was a critical one, for it made possible the full extension of American military and economic power into the European Theater.

That power was principally represented in the air in 1943. The Combined Bomber Offensive was officially launched as Operation Pointblank in June 1943, although British Bomber Command and the U.S. Eighth Air Force had begun around-the-clock bombing -- the British by night, the Americans by day -- from the winter of 1942-43. The offensive was aimed at the enemy's military-economic complex -- the source of German airpower and the morale of the urban workforce.

The Russian victory in the Battle of Kursk drove Nazi Germany out of central and southern Russia and opened the way to victory in the East.
The Russian victory in the Battle of Kursk drove Nazi Germany out of central and southern Russia and opened the way to victory in the East.

Efforts to attack identifiable industrial or military targets could not be achieved with prevailing technology without a high cost to civilians. Over the course of the war, more than 420,000 German civilians would die from the bombing attacks; a further 60,000 civilians would be killed in attacks on Italian cities.

The bomb attacks immediately affected German strategy. The Germans established a large air defense sector. To do so, they had to withdraw valuable resources of manpower, artillery, shells, and aircraft from the military front line. There, German armies were forced to fight with shrinking air cover. Though military production continued to rise in Germany during 1943, the increase was much lower than it would have been otherwise. Bombing placed a ceiling on the German war effort and brought the war to bear directly on German and Italian society.

The Allies capitalized on these growing advantages. In North Africa, the Axis forces that were bottled up in Tunisia were slowly starved of supplies by Allied naval and air power in the Mediterranean. By May 13, when the battle was over, 275,000 Italian and German troops had surrendered.


The Allies' pressure at sea, in the air, and on the southern front made the Axis task in the Soviet Union more difficult. Following the collapse of the German assault on the Caucasus and Stalingrad, the Red Army became overly ambitious. After the Soviets pressed the German army back, a swift counteroffensive around Kharkov in early 1943 was a reminder that the huge German army remained a formidable foe. Adolf Hitler listened to the advice of his generals, who argued that in summer weather, with good preparation, they could smash a large part of the Soviet army in a single pitched battle. They chose a large salient that bulged into the German front line around the city of Kursk as their battleground.

Operation Citadel lacked the geographical scope of previous operations, but it became one of the largest set-piece battles of the whole war. It followed a classic German pattern: Two heavily armored pincers would close around the neck of the salient, trapping the Soviet armies in the salient and creating conditions for a possible drive into the areas behind Moscow. Manstein, who commanded the southern pincer, wanted to attack in April or May, before the Red Army had time to consolidate its position. But Adolf Hitler, in agreement with General Model (who commanded the northern pincer), ordered a delay until German forces were fully armed with a new generation of heavy tanks and guns -- the Panthers and Tigers.

The Soviets, for the first time, guessed the German plan correctly. Stalin had to be persuaded by Georgi Zhukov and the General Staff that a posture of embedded defense was better strategy than seeking open battle against a powerful mobile enemy. Stalin accepted it only because the defensive stage was to be followed by a massive blow struck by Soviet reserves against the weakened and retreating German armies. In May and June, a vast army of Soviet civilians turned the Kursk salient into a veritable fortress, and they waited for the Nazi attack.

Hundreds of thousands die at Treblinka: Before Jews and other enemies of the Third Reich were exterminated at the Treblinka death camp in Poland, their shoes (and other possessions) were confiscated. This image alone suggests that a huge number of people met their fates at Treblinka. In fact, more than 700,000 Jews died at the camp, a death toll exceeded only at Auschwitz. Most of the victims came from such major ghettos as Warsaw (250,000 in the summer of 1942) and Bialystok, while others endured (or died during) long train rides from Czechoslovakia, Greece, and other countries. Deportations to Treblinka ended in May 1943.

Soldiers endure wretched conditions in New Guinea: Australian infantrymen fight in New Guinea in this painting by Henry Hanke. The Japanese naval offensive toward Port Moresby in New Guinea in 1942 raised justified concerns that an invasion of Australia was imminent and prompted the recall of Australian troops from the Middle East. Australians shouldered the brunt of the early fighting in New Guinea, as significant numbers of U.S. troops were not available. Plagued by disease and constant rain -- their movement limited to muddy footpaths over steep, jungle-choked mountains -- soldiers on both sides suffered terrible hardships during the seven-month campaign.

British agent Nancy Wake known as the "White Mouse": Nancy Wake used her position as wife of a wealthy French businessman to help the French Resistance. She served as courier, obtained false papers, bought an ambulance to aid fleeing refugees, and helped get some 1,000 escaped prisoners and downed Allied fliers out of France. By 1943 Wake -- called the "White Mouse" because she was so hard to catch -- topped the Gestapo's most-wanted list. She fled to Britain, was trained by the SOE (Special Operations Executive, a spy agency), and then parachuted back into France. There she served as liaison between London and the Maquis, and also led guerrilla raids.

Allied propaganda warns U.S. workers: Allied propaganda typically portrayed the Japa­nese as nearsighted, bucktoothed caricatures or as monkeys, alternating between a subject of ridicule and an object of fear. This particular piece, probably made to be posted in U.S. defense plants, reminds workers that goldbricking hurts productivity and aids the enemy. It also links Japan to its Axis partner, Germany, through the subject's swastika collar medallion.

Before and after aerial photos of the bombing of Wilhelmshaven: The German port city of Wilhelmshaven was bombed twice in 1943 -- once by the USAAF on January 27, and again by the RAF Bomber Command on February 11-12. These aerial reconnaissance images show Wilhelmshaven before and after the two bombings. The second bombing, carried out at night, was especially challenging because of dense cloud cover. Planes equipped with the RAF's newly developed H2S ground-mapping radar located strategic targets, then illuminated them with parachute flares. A successful strike on a naval ammunition dump south of Wilhelmshaven caused widespread destruction of dockyards and the city.

Air Force machine gunner most dangerous position: U.S. Army Air Force machine gunner Sergeant William Watts fires at enemy planes from a bomber over Europe in 1942. Almost 300,000 aerial gunners were trained during World War II -- a substantially greater number than were trained as pilots, navigators, or bombardiers, and for good reason. A bomber's very survival depended upon the gunners' skill at fending off enemy planes. Gunners also held the crew's most dangerous and physically disagreeable positions. They were unprotected by armor, and because of high altitudes, they sometimes had to endure temperatures as low as ­minus-60 degrees Fahrenheit.

Adolf Hitler loses support of some generals: Adolf Hitler and his generals study maps in February 1943. From the left are General Field Marshal Erich von Manstein, Adolf Hitler, General Theodor Busse, and General Field Marshal Ewald von Kleist. Hitler had made himself supreme military commander early in the Nazi reign. In December 1941, he became commander-in-chief of the German army. By 1943 devastating failures on the Eastern Front and in North Africa had convinced some German generals that they could save their nation only by getting rid of the Führer. However, a bomb placed on a plane carrying Adolf Hitler to Smolensk in March failed to go off, and several other attempts on the Führer's life also failed.

Tresckow involved in Hitler murder plots: "Hitler is not only the very enemy of Germany, but the enemy of the world." This sentiment was expressed by German Major General Henning von Tresckow, chief of staff of the German Army Group Center. Although an officer, Tresckow hated Adolf Hitler and was a leader in the military resistance. An attempt to blow up Hitler in a plane in March 1943 was unsuccessful. Another attempt at a meeting in July 1944 also failed. Learning of this latest failure and realizing it could be traced back to him, Tresckow killed himself a day after the attempt.

Ernst Kaltenbrunner named head of Gestapo: As head of the Austrian SS, Ernst Kaltenbrunner assisted in the 1938 German annexation of Austria, enforced anti-Jewish measures, and opened a death camp. In 1942 he replaced assassinated Gestapo chief Reinhard Heydrich, assuming responsibility for the Nazi "Final Solution" to the "Jewish question." Kaltenbrunner claimed ignorance of genocide when he was brought to trial at Nuremberg, but he was found guilty and hanged. More than 50 years later, his personal seal identifying him as head of the Nazi security police was discovered in an Alpine lake, where he had apparently tossed it before surrendering under a false name.

U.S. Coast Guard contributes to war effort: On April 17, 1943, U.S. Coast Guardsmen watch the explosion from a depth charge they have dropped on the German submarine U-175. Spotting the U-boat on sonar as it maneuvered to attack an Allied convoy in the mid-Atlantic, the Coast Guard cutter Spencer took the submarine by surprise. Coast Guardsmen boarded the badly damaged submarine when it surfaced and rescued the surviving 41 German crewmen. In the Atlantic, the Coast Guard sank 13 U-boats and captured two Nazi surface ships. In the Pacific, they sank at least one Japanese submarine.

Allied make significant gains in North Africa: In the fall of 1942, General Montgomery's Eighth Army inflicted a significant defeat upon General Rommel's Afrika Korps at El Alamein in Egypt. At last the tide of German successes had turned, as Alamein now opened the way for a general advance westward by the British. Simultaneously, Anglo-U.S. landings (Operation Torch) at Casablanca, Oran, and Algiers were largely unopposed by the Vichy French defenders. Tripoli fell on January 28, 1943, and in February the Allies entered Tunisia -- where U.S. forces suffered a costly reverse at Kasserine Pass. However, the end was in sight, and the remaining Axis forces in North Africa surrendered on May 12.

These headlines and images detail more events of World War II and some of the consequences of the Allied campaign.

Allies prevail in North Africa: On May 6, 1943, the Allies launched their last offensive against the Axis in North Africa. On May 13, the German and Italian troops in Tunisia surrendered. This was the first major success of the alliance between America and Britain. It was not only good for the morale on the home front, but it also took some pressure off President Franklin Roosevelt to turn the military's attention primarily to the fight in the Pacific. To promote this success, director Frank Capra prepared this 75-minute documentary of the North Africa campaign, beginning with Operation Torch and ending with the fall of Tunisia.

Armored cars important to desert campaign: From the outset, the main belligerents' armored forces included armored cars. Their primary roles were reconnaissance and scouting, so they needed to be faster and quieter than tanks, and to have a better range. Typically they had thin armor, light or nonexistent armament, and limited cross-country performance. This vehicle, a British Daimler, fires its two-pounder (40mm) gun near Tripoli in January 1943. Daimler armored cars performed well in the desert from their introduction in 1941. They served throughout the war, with nearly 2,700 produced.

British Admiral Sir Max Horton's ideas lead to success in Atlantic: Late in 1942, British admiral Sir Max Horton, commander-in-chief of the Western Approaches Command, changed antisubmarine strategy. He sent groups of fast "hunter-killer" ships away from their convoys to attack German U-boats, preventing the formation of "wolf packs." By spring 1943, those tactics had successfully reopened the North Atlantic to merchant and military shipping. As a WWI submarine commander, Horton had responded to an admiral's assessment of all submariners as "un-English" and "pirates" by flying the "Jolly Roger" (skull and crossbones flag) after his sub sank two German ships. WWII British and Australian submariners took up the Jolly Roger as a signal of success.

American fears lead to invasion of Attu: Soldiers unload supplies during the invasion of Attu. The recapture of this remote, inhospitable island in the American Aleutian chain (off Alaska) cost the lives of 549 Americans from May 11-31, 1943. The operation was prompted by fears that the island -- seized by the Japanese in June 1942 -- could serve as a base for air attacks on the U.S. mainland and threaten sea lanes between Seattle and the Soviet Union. Hindsight indicates that the invasion was driven as much by national pride and a determination to eject Japanese occupiers from American soil than by any overwhelming strategic concerns.

Chinese, Japanese battle in Burma: Chinese soldiers battle Japanese units along the Salween River in Burma in June 1943. Spurred by American insistence, 16 Chinese divisions commanded by General Wei Li-Huang crossed the river on the night of May 11-12, 1943. Their mission was to trap enemy forces by seizing key terrain north and south of the Burma Road. Fierce Japanese resis­tance slowed the attack. Chinese forces to the south reached the outskirts of Lung-ling on the Burma Road in early June before a counterattack pushed them back. Lacking adequate supplies, the Chinese offensive finally stalled.

April 26: Angered by the investigation and accusations surrounding the Katyn massacre, Soviet officials sever diplomatic relations with Poland's government-in-exile.



A United States force reaches Alaska and begins its assault on the Japanese-held Aleutian island of Attu.

April 28-30: German panzer units attack Djebel Bou Aoukaz, Tunisia, in what will be Nazi Germany's last offensive armored maneuver in North Africa.

April 30: The British launch Operation Mincemeat by releasing a corpse -- which is dressed as a British officer and carries falsified war plans -- off the coast of Spain. The "plans," which indicate that the Allies will attack Greece and Sardinia, and not Sicily as long suspected, will successfully divert Axis defenses from several key fronts.

May: War shortages affect civilians on both sides of the Atlantic, as Canada introduces meat rationing while Nazi Germany further reduces the size of existing rations.

Due to improved Allied interception technology, Nazi Germany will lose a third of its U-boats out on patrol this month. This leads German admiral Karl Dönitz to implicitly concede an Allied victory in the Battle of the North Atlantic when he repositions his fleet to the south.

Sold at 75 percent of its face value, a "war bond" matured in 10 years to $25, $50, $75, $100, $200, $500, $1,000, or $10,000. War bonds were promoted on posters, in ads contributed by radio stations and print publications, at sports events, and via celebrity appearances. More than 85 million Americans (most of the population) spent a total of more than $185 billion on War Bonds -- at a time when the median annual income was about $2,000. The bonds helped finance the war effort and took cash out of the economy to control inflation.

Soviets halt German advance: Soviet tanks, troops, and artillery stubbornly fought the advancing Germans, inflicting heavy casualties for each mile gained. As the Second SS Panzer Corps advanced on July 12 out of the town of Prokhorovka, it was met by the Soviet Fifth Guards Tank Army. About 1,200 tanks participated in this battle, the largest tank fight of the war. Although the Soviets suffered many more casualties than the Germans, the advance was halted. The Allied invasion of Sicily caused Adolf Hitler to order the Second SS Panzer Corps to Italy. Facing weakened resistance, the Soviet Union launched an offensive, which it would maintain until the end of the war.

Soviets practice scorched-earth policies: As the Nazi German Army pushed the Soviets through the Ukraine in 1941 and 1942, Joseph Stalin ordered his army and civilians to destroy anything that could be useful to the Germans, including industrial facilities, rail lines, communication lines, and shelter. The Germans practiced their own scorched-earth policy in 1943 and 1944 as they retreated through Russia and Europe. As his country was collapsing in March 1945, Adolf Hitler ordered his armaments minister, Albert Speer, to destroy any German resources not yet in Allied hands. Unknown to Hitler, Speer never carried out the order.

Nazis force Ukrainians to work in German factories: Once the German army occupied the Ukraine, it attempted to attract large numbers of workers for German factories. Failing to supply the necessary number of workers voluntarily, the occupying troops began to ship large numbers of Ukrainians to Nazi Germany forcibly. Called Ostarbeiter (East workers), about three million were eventually deported to manufacture war supplies for the German army and other work. Many died from overwork and starvation while others were killed in Allied attacks on German factories. After the war, most workers were repatriated to the Ukraine, where many were killed or imprisoned by the Soviets on political grounds or because of purported collaboration.

Important American cargo ships made treacherous voyages: This painting by American artist Thornton Oakley shows a U.S. cargo ship unloading scrap materials -- indicating both Nazi and U.S. air force losses -- to be recycled. In the background, more ships wait. Cargo ships carried food, ammunition, clothing, guns, and troops. These U.S. merchant vessels came in all sizes and were outfitted with cranes for loading and unloading. They were subject to destruction by mines, battleships, bombers, submarines, and kamikaze attacks. During the war, 733 cargo ships were lost and more than 5,000 U.S. merchant seamen were killed.

Allied invasion of Sicily slowed by intense heat, resistance: Rough terrain and the stubborn resistance of German troops slowed the Allied advance across Sicily. Oppressive heat (100°F) also affected the advance. More than 10,000 Allied soldiers became sick with heat exhaustion and malaria. Those Allied troops who could still fight found that the enemy would not go down easily. The British capture of the town of Centuripe exemplified the intensity of combat. The British 78th Division launched its attack on the town on July 31, and needed four days of treacherous house-to-house fighting to finally capture it.

British admiral Sir Andrew Browne Cunningham stars in Mediterranean: British admiral Sir Andrew Browne Cunningham, the naval commander-in-chief in the Mediterranean, aggressively destroyed Italian warships and ran supplies to Malta. Using obsolete Swordfish aircraft, he mounted the first all-aircraft naval attack in history at Taranto in November 1940, cutting the Italian fleet in half. When Germany seized Crete in May 1941, Cunningham insisted on evacuating 16,500 trapped Allied troops in the face of heavy Luftwaffe opposition. He commanded the Naval Task Forces during Operation Torch -- the November 1942 British-American invasion of French North Africa -- under General Dwight Eisenhower, who praised Cunningham for his intelligence, devotion, and selflessness.

As June 1943 progressed, the Allies continued their bombing of Sicily in preparation for invasion. Read about this and other major World War II events on the timeline on the next page.

Soviet cavalry forces prove valuable in battle: In 1946 a U.S. Intelligence Bulletin reported, "Red Army cavalry units have proven the right of the almost legendary Cossack to remain part of the armed forces of the U.S.S.R." Mounted troops such as these could move through forests, swamps, and other terrain impassable by mechanized forces. They also could avoid air attacks by operating at night. Mounted troops sometimes flanked enemy units, staging surprise counterattacks and setting up roadblocks against retreats. The cavalry filled in gaps on the battlefield and covered Soviet withdrawals. Where needed, they dismounted and operated as infantry forces.
