Working with
"Tim" Walenn the camp’s head of forgery and
Henri Picard they produced forged passports, movement orders, railway documentation and all manner of identity papers to move about Germany. Brettell was one of the 76 men who escaped the prison camp on the night of 24–25 March 1944, in the escape now famous as "
the Great Escape". Travelling in a group of four escapees with
Tim Walenn,
Romualdas Marcinkus and
Henri Picard, all posing as Lithuanian workers they managed to reach a train heading towards Danzig (now
Gdańsk, Poland). Most likely, they intended to travel to East Prussia and cross the Lithuanian border hoping to cross the Baltic Sea to neutral Sweden. When the Germans discovered the escape they began manhunts. Brettell and his group travelled further than most of the escapees but were captured by the
Gestapo near
Schneidemühl on 26 March. The party of four were brought to
Stalag XX-B and spent the night there. On the following day they were handed over to the Danzig
Gestapo. Its officials took the men to a forest near Gross Trampken (Trąbki Wielkie) and executed them. On 29 March, his body was cremated in Danzig's crematorium. He was one of the
50 escapers executed and murdered by the
Gestapo. His ashes, originally buried at Sagan, are now buried in part of the Poznan Old Garrison Cemetery. Brettell's name was amongst those in the list of the murdered prisoners which was published when news broke on or about 20 May 1944. ==Awards==
