In October and November 1942, the Allies fought a famous battle against German and Italian troops close to the small Egyptian village of El Alamein.

General Bernard Montgomery, the British commander, knew that victory was crucial. But his offensive was in danger of stalling almost as soon as it began.

Witness speaks to Len Burritt who was then a 24 year old wireless operator with the British Seventh Armoured Division.

Using archive recordings we tell the story of Britain's most famous hangman. During the 1940s and 50s, he was responsible for the execution of some of Britain's most notorious murderers and was sent to Germany to hang more than 200 Nazi war criminals after WW2. He said he was always determined to treat prisoners with dignity and respect whatever their crime. He initially appeared to support the abolition of the death penalty.

In the 1930s, many parts of Britain were suffering the effects of the Great Depression.

But conditions were particularly harsh in the town of Jarrow, in the north-east of England. In 1936, two hundred men marched the 300 miles from Jarrow to London to protest against mass unemployment and to demand that new industries be established in their town. They called it the Jarrow Crusade.

Witness delves into the BBC archives to hear the voices of the marchers.
