Biggs was sent to Wandsworth prison, a maximum security prison. It had one very high wall to keep the prisoners in, and some guards to watch them. One afternoon in July 1965,Biggs was in the prison yards he had been in prison for just fifteen months. A talk ban stopped outside the prison,and a ladder was places against the wall. Then a rope ladder was thrown over the wall into the prison yard. Biggs climbed up the rope ladder, jumped down into the van and escape!
