The uprising - triggered by the Nazis' decision to send residents to concentration camps - lasted three weeks before it was crushed.
Mr Edelman, then 23, was one of 200 young Jews who fought German troops.
... For nearly a month in the spring of 1943 a group of young Jews, armed with pistols and home-made bombs, held off the German army before the ghetto was razed to the ground.
By that time the Nazis had sent 300,000 Jewish residents of the ghetto to the gas chambers at the Treblinka death camp.
The first clashes occurred at the start of 1943 as residents took up arms to prevent more Jews being sent to the camp.
The full-scale uprising began in April in response to Nazi plans to wipe out the 60,000 remaining inhabitants.
Thousands of Jews died in the fighting as Nazi troops resorted to explosives to destroy the ghetto - created by the German occupiers in 1940.
REST IN PEACE.
