One of the most basic ideas in the laws of war is that a soldier who surrenders is no longer supposed to be attacked. A raised hand, a white flag, or a decision to stop fighting should mark the end of combat for that person. Yet in World War II, that line was often crossed. In multiple theaters of war, Allied troops killed enemy soldiers who were trying to surrender or had already surrendered.
This was not unique to one army or one front, but it was especially common on the Eastern Front and in the Asia-Pacific war. The pattern is disturbing because it shows how quickly the protections meant to limit war could collapse under pressure from fear, hatred, revenge, and the brutal logic of total war.

What counts as a war crime here?
After the war, the Charter of the International Military Tribunal defined war crimes as violations of the customs of war, including the murder or mistreatment of civilians and prisoners of war, often shortened to POWs. A POW is a captured member of an enemy armed force. Once someone is captured or has clearly surrendered, they are no longer supposed to be treated as an active combatant.
The major Western Allies were formally directed to follow the Hague Conventions and Geneva Conventions, which were international agreements intended to regulate warfare. These rules covered issues such as treatment of prisoners and limits on certain kinds of violence. Even where legal details were debated, the basic principle was clear: killing someone who has stopped fighting and is trying to surrender is outside the accepted customs of war.
The Eastern Front: surrender was especially dangerous
The fighting between Germany and the Soviet Union in Eastern Europe, known as the Eastern Front, was one of the deadliest and most brutal theaters of World War II. In this environment, prisoners were often treated with extreme cruelty.
The Soviet Union inflicted very high death rates on POWs through executions, starvation, forced labour, and other mistreatment. Forced labour means compelling captives to work under coercion, often in harsh and dangerous conditions. The Soviet forced-labour camp system was known as the gulag.
About a third of Germans taken prisoner by the Soviet Union died in captivity. The article contrasts this with the mortality rate for German and Japanese prisoners held by the Western Allies, which was about 1 to 2 percent. That gap captures how deadly Soviet captivity could be.
Mistreatment of prisoners was common on the Eastern Front partly because the Soviet Union had not ratified the Geneva Convention on POW treatment. Still, the Nuremberg Tribunal later held that the Hague Conventions and other customary laws of war were binding on all belligerents. In other words, not signing a treaty did not erase the obligation to follow core rules of war.
The Soviet record extended beyond neglect or poor camp conditions. The Soviet Union was responsible for imprisoning, deporting, and often massacring civilians and POWs from occupied or annexed territories. It also made extensive use of forced labour and sent many deported civilians and prisoners into the gulag.
The Pacific war: “everyday practice” in some areas
In the war against Japan, the killing of surrendering troops and prisoners was also particularly common. Historian John W. Dower wrote that while taking no prisoners was not official Allied policy, over wide stretches of the Asian battleground it became “everyday practice.”
Several explanations were given for why this happened so often. Historians cited the bitterness of the fighting, reports that Japanese forces mistreated Allied soldiers and POWs, and cases where Japanese troops faked surrender in order to launch surprise attacks. Allied propaganda that dehumanised the Japanese and the logistical difficulty of handling prisoners also contributed.
Even so, senior American officials did try to suppress the practice. Some commanders offered inducements to troops who took prisoners, and General Macarthur ordered investigations into alleged shootings of surrendering Japanese. Propaganda leaflets even assured Japanese troops that if they surrendered, they would be treated according to the Geneva Conventions. These efforts may have had some effect: one historian cited a change in the captured-to-killed ratio of Japanese soldiers from 1:100 in late 1944 to 1:7 by July 1945.
That improvement only underlines how grim conditions had been before. In many areas, surrender offered little assurance of survival.
American cases in Europe and the Pacific
The United States was involved in multiple incidents where surrendering troops or POWs were killed.
In western Europe, there were recorded instances during the Normandy campaign of American soldiers shooting wounded, captured, or surrendering enemy troops and mutilating bodies. There were also incidents in which American forces killed prisoners in large numbers. Among the best-known examples were the Biscari massacre of 11 July 1943, in which 73 Italian and German prisoners were killed, and the Chenogne massacre, in which 50 to 80 German prisoners were shot. After the liberation of Dachau concentration camp in April 1945, about 30 to 50 German guards were also killed.
The article also notes that illegal orders to take no prisoners were sometimes issued. In July 1943, General Patton gave a speech that some officers in the US 45th Division understood as an order to shoot enemy prisoners. After the Malmedy massacre, in which SS troops killed American POWs in December 1944, some American units issued formal or informal orders not to take SS prisoners, and sometimes no German prisoners at all. Major-General Raymond Hufft admitted he gave orders to take no prisoners when his troops crossed the Rhine.
In the Pacific, there were additional examples. On 26 January 1943, the American submarine USS Wahoo sank the Japanese transport ship Buyo Maru off New Guinea. Its commander then ordered fire on survivors in the water and on lifeboats, believing they were Japanese troops. In fact, most of the survivors were British Indian prisoners of war. The attack on survivors breached international law.
During and immediately after the Battle of the Bismarck Sea in March 1943, American patrol boats and Allied aircraft systematically attacked survivors from Japanese warships and troop transports. The justification given was that these survivors were troops close to their base who could quickly return to combat.
Why surrender protections broke down
The collapse of surrender protections was often tied to emotion as much as strategy. The article points to revenge, especially after atrocities committed by the enemy, as one factor. Hatred and dehumanisation also mattered. So did the atmosphere of total war, where the line between battlefield necessity and unlawful killing could be blurred in practice, even if not in principle.
But the central moral problem remains simple. Once a soldier is trying to surrender or has already surrendered, continued violence is no longer combat in the ordinary sense. It becomes the killing of a captive or a helpless person.
That is what makes these cases so unsettling. They expose how fragile the rules of war can become when armies are pushed into extreme brutality.
The larger historical debate
In recent decades, historians and commentators have paid more attention to Allied war crimes, including crimes against prisoners and civilians. At the same time, they warn against arguments of “moral equivalence,” meaning claims that Allied wrongdoing somehow cancels out or equals the crimes of the Axis powers.
Looking closely at these killings matters not because it erases larger differences in the war, but because it reveals a hard truth: even armies fighting against deeply criminal regimes could commit serious crimes of their own. The fate of surrendering soldiers in World War II is one of the clearest and most chilling examples.
