The attack on Heydrich
Carried out the attack on Heydrich on 27 May 1942 and later died during the siege of their Prague hiding place. Lidice had no established operational connection to either man.

1937 to 1945 · Occupied Europe and Asia · Collective punishment, anti-partisan terror and occupation massacre
German occupation forces used reprisals to punish resistance and intimidate civilians. In Serbia, this included executions under fixed hostage ratios. Elsewhere, collective punishment took the form of shootings, village destruction and anti-partisan terror. The methods differed, but civilians repeatedly became the targets of retaliation and occupation violence.

German reprisal policy was set out with unusual clarity in an OKW order issued on 16 September 1941. Wilhelm Keitel instructed commanders that attacks on German forces should be answered with severe retaliatory measures, proposing the execution of 50 to 100 people for every German soldier killed. In occupied Serbia, German commands applied an even more rigid scale: 100 hostages for each soldier killed and 50 for each soldier wounded. The mass shootings at Kragujevac in October 1941 became one of the most notorious applications of this policy.
The purpose was to deter resistance by making entire communities vulnerable to punishment. Those selected for execution did not need to have taken part in the attack that triggered the reprisal. Hostages were taken from prisons, political lists and the civilian population, while proclamations and posted notices warned that further attacks would bring further executions. Wehrmacht units participated alongside German police and SS formations in carrying out these measures.
The term reprisal, however, describes a policy and method rather than a single explanation for every massacre under Axis occupation. Lidice was destroyed after the assassination of Reinhard Heydrich in a deliberately ordered act of retaliation. Oradour-sur-Glane and Sant'Anna di Stazzema occurred within anti-partisan operations and systems of occupation terror, but under different immediate circumstances. The mass killings at Nanking followed the Japanese capture of the city and were not based on a German-style hostage ratio.
What links these events is not one formula, but the treatment of civilians as legitimate targets for punishment, intimidation or destruction. Their causes, orders and methods differed, and those distinctions matter.
Keitel’s directive of 16 September 1941 survives in the Nuremberg record. It described the execution of 50 to 100 people as an appropriate response to the death of a German soldier and was circulated through the German command structure. During the uprising in occupied Serbia, military authorities imposed a more specific scale: 100 hostages for every German soldier killed and 50 for every soldier wounded. The Serbian ratio therefore grew from a broader reprisal policy, rather than serving as a single rule applied throughout occupied Europe.
The destruction of Lidice followed a different chain of command. Reinhard Heydrich died on 4 June 1942 from wounds sustained in the assassination attempt in Prague. In the reprisals that followed, Karl Hermann Frank communicated the decision to destroy Lidice. No evidence had established that the village or its inhabitants were involved in the attack. Horst Böhme, commander of the Security Police and SD in the Protectorate of Bohemia and Moravia, oversaw the security-police operation.
Elsewhere, anti-partisan warfare gave German commanders wide latitude to destroy settlements, execute civilians and punish communities accused of supporting resistance. Such measures were used across the occupied Soviet territories, Greece, the Balkans and Italy, but the circumstances and command structures varied from place to place.
At Sant'Anna di Stazzema, the killings were not tied to a fixed hostage ratio or to retaliation for one identified partisan attack. Later Italian investigations and prosecutions treated the massacre as part of a deliberate operation against the civilian population, intended to terrorise communities in an area where partisan forces were active.

The attack on Heydrich
Carried out the attack on Heydrich on 27 May 1942 and later died during the siege of their Prague hiding place. Lidice had no established operational connection to either man.

Chief of the OKW, the ratio directive
Signed the September 1941 directive that proposed fifty to one hundred executions for one German soldier killed. The order helped formalise collective punishment as a command policy across occupied territory.

Applying the ratio at Kragujevac
As Plenipotentiary Commanding General in occupied Serbia, oversaw the repression in which German commands applied the 100-for-death and 50-for-wound formula. Kragujevac became its most notorious mass shooting.

His assassination, and the reprisal it produced
His assassination in Prague triggered the wave of arrests and executions that culminated in Lidice and Ležáky. His earlier role in Nazi persecution belongs to the Holocaust section; here the focus is the retaliation ordered after his death.

Implementing the destruction of Lidice
As commander of the Security Police and SD in the Protectorate, helped implement the destruction of Lidice after the decision had been transmitted through the occupation leadership.

Commanding the assault on Nanking
Commanded the Central China Area Army during the capture of Nanking. He was convicted by the International Military Tribunal for the Far East for failing to prevent atrocities by forces under his command.

Division commander during the Sant'Anna di Stazzema massacre
Commanded the 16th SS Panzergrenadier Division Reichsführer-SS during the 1944 anti-partisan campaign in Italy. Units of the division carried out the Sant’Anna and Monte Sole massacres.

Occupation leadership during the Lidice reprisal
Pressed for a spectacular retaliation after Heydrich’s death and transmitted the decision that led to the annihilation of Lidice. He was tried and executed in Prague in 1946.

Acting Reich Protector after Heydrich
Became acting Reich Protector after Heydrich’s death and presided over the occupation regime during the retaliatory terror of June 1942. He was convicted and executed in Czechoslovakia in 1946.

A surviving witness to Oradour-sur-Glane
Survived the shooting of the men at Oradour-sur-Glane and later became one of the massacre’s principal public witnesses, describing the killings and the destruction of the village for decades.
Reprisals often began with measures already established by the occupation authorities. Hostages were designated or detained in advance, names were drawn from prisons and administrative records, and public notices warned that attacks on German forces would bring collective punishment. These arrangements allowed arrests and executions to be organised quickly after an incident.
Once a reprisal was ordered, troops might seal off a town or village, assemble civilians, separate groups for detention or execution and determine how many people were to be killed. In places where fixed ratios were applied, administrative records became part of that process. Orders, lists, reports and execution records helped turn collective punishment from an exceptional response into a method that could be repeated.
There was no single sequence followed in every operation. Hostage shootings remained in use while anti-partisan forces also carried out large-scale sweeps in which settlements were searched, civilians were assembled or expelled, buildings were burned and suspected resistance areas were destroyed. Shooting, burning and demolition could all form part of the same operation.
The eight cards below therefore represent methods used to organise and carry out reprisals and occupation violence, rather than a progression of weapons or tactics.

Occupied Paris · August 1941 · civilians designated as hostages
A public notice could make collective punishment part of everyday occupation. This German proclamation announced that hostages would be taken after the killing of a German naval officer in Paris and threatened executions if further attacks occurred.

Kragujevac · 21 October 1941 · 100 for a death, 50 for a wound
The occupation command announced the shootings in writing after they had been carried out. The notice linked the death and wounding of German soldiers directly to a fixed number of people executed.

Kragujevac · civilians seized for a numerical reprisal · October 1941
Once a quota had been set, troops still had to find the people who would fill it. German forces swept Kragujevac and nearby communities, taking workers, tradesmen, pupils, teachers and other civilians into custody before the mass shootings.

Kragujevac · names recorded before execution · 21 October 1941
The killings were administrative as well as physical. Men taken in the Kragujevac roundup were registered before being sent to the execution grounds, leaving a paper process beside the numerical order that had selected them.

Occupied Poland · hostages killed in public · 15 June 1941
Public killing was itself part of the deterrent. Ten Polish hostages were executed at Gąbin in June 1941, before Keitel's September directive, showing that collective punishment and exemplary public violence already formed part of German occupation practice.

Occupied Soviet Union · mobile security operation · May 1943
By 1942 and 1943, anti-partisan warfare often treated the civilian environment itself as a security target. Mobile police, SS and army formations searched settlements, forests and marshlands, seized civilians and destroyed communities under broad anti-partisan directives.

Yugoslavia · buildings burned during a police operation · 1943
Burning a settlement could punish a population, deny shelter and supplies to resistance groups and erase the physical community at once. Fire and demolition therefore accompanied shooting in many anti-partisan operations.

Prague · official announcement · 11 June 1942
The destruction of Lidice was publicised immediately. The German-language government newspaper Der Neue Tag announced the action, turning the annihilation of the village into a warning addressed to the wider Czech population.

Lidice · buildings demolished · landscape altered · 1942
Reprisal could continue after the victims were dead. At Lidice the buildings were demolished, the cemetery destroyed and the ground altered so the settlement would disappear physically as well as administratively. Preserving the ruins and site after 1945 reversed that intended erasure.

Kalavryta · December 1943 · killing followed by systematic burning
Village destruction altered both civilian survival and the physical landscape. The burning of Kalavryta followed the mass execution of local men and formed part of a wider German operation across the surrounding area.
At Lidice, 340 residents were killed as a result of the destruction of the village and the subsequent murder of deported children. The memorial at Oradour-sur-Glane now records 643 victims, replacing the figure of 642 found in many older accounts. Around 560 people were killed at Sant'Anna di Stazzema. At Kragujevac, the Museum "21 October" has identified 2,796 civilians killed during the mass shootings of October 1941.
Figures for destroyed villages describe a different scale of violence. More than 1,000 Greek villages were reported destroyed or severely damaged during the occupation, but that figure includes communities affected under different circumstances and cannot be treated as a count of reprisal actions alone. In Belarus, the Khatyn memorial represents a much broader campaign of village destruction, including more than 600 settlements where inhabitants were killed.
The surviving records also measure different things. Some count people executed, others settlements burned, populations expelled or villages destroyed. Definitions changed between occupation authorities, post-war investigations, national archives and later memorial institutions.
There is therefore no single total on this page for deaths caused by "reprisals." A hostage execution ordered according to a fixed ratio, the destruction of a village during an anti-partisan operation and mass killing following the capture of a city belong to different historical contexts. Presenting them separately preserves both the scale of the violence and the circumstances in which it occurred.

The legal aftermath did not produce one uniform reckoning. Keitel was convicted at Nuremberg and executed in 1946. Franz Böhme died by suicide in custody before judgment in the Hostages Trial. Karl Hermann Frank and Kurt Daluege were tried and executed in Czechoslovakia. Max Simon was convicted by a British military court, while later Italian proceedings revisited responsibility for massacres committed by his division.
Oradour produced its own political crisis when the 1953 Bordeaux trial included Alsatian conscripts who had been forcibly incorporated into the Waffen-SS. The sentences and subsequent amnesty divided survivors’ families and Alsace. Other cases generated extradition disputes, compensation litigation and renewed investigations decades later.
Memorialisation became part of the historical record. Lidice was rebuilt beside the erased village, Oradour’s ruins were preserved, Khatyn became the national symbol for destroyed Belarusian communities, and Monte Sole was turned into a historical park. These sites preserve both the local event and the problem of how later societies chose to name, count and remember civilian massacre.
The written German policy is unusually well documented because Keitel's directives and the orders applying them survived into the Nuremberg record. The Kragujevac figure used here follows the named victims documented by the Museum '21 October' rather than the much larger figures repeated in early postwar memory.
For individual massacres this page follows the institutions responsible for the surviving local record: the Lidice Memorial, the Centre de la mémoire d'Oradour and the Sant'Anna di Stazzema memorial archive. Their current counts occasionally differ from older histories, which is why Oradour is given here as 643 rather than the long-standard 642.
