On 15 April 1945, British forces entered Bergen-Belsen concentration camp for the first time.
Upon arriving at Bergen-Belsen in Northern Germany, soldiers from the 63rd Anti-tank Regiment and 11th Armoured Division of the British Army were completely unprepared for the atrocities they would face. It was here they were met with the full horrors of the Holocaust.
Soldiers encountered thousands of unburied bodies laying around the camp. 60,000 people, mostly Jews, were starving, mortally ill and in desperate need of medical attention. They were packed together without water or basic sanitation and many were suffering from diseases such as typhus and typhoid.
What immediately followed was a large-scale relief effort. The first priorities were to organise the burial of those who had died and to introduce a form of quarantine to contain the spread of disease.
The army organised emergency medical aid, restored the water supply and arranged for the distribution of food that was suitable for starving prisoners suffering from malnutrition. Additional military and civilian medical personnel were brought in to support the relief effort.
Video: Face to face with Nazi brutality: Liberating Bergen-Belsen

All official documents had been destroyed by the Nazis before the Allies had arrived at the camp.
Without the extensive photographic and video evidence captured by the the Army Film and Photographic Unit (AFPU) following the liberation of Bergen-Belsen, the atrocities that took place in the camp could not have been conceived.
Using objects on display at The Holocaust Galleries at IWM London, IWM's head of public history, James Bulgin, examines the monumental scale of horror wrought by the Nazi regime, the relief effort that took place and the aftermath following the liberation of Bergen-Belsen.
