Market Garden, Cadet bolt action introduction
The Bunker on Arnhem Bridge
On the Morning of the 17th of September citizens of Arnhem witnessed a British aircraft diving on Arnhem road bridge. It’s target was a 2cm Flak gun positioned atop a bunker on the bridge. Whilst the gun was destroyed the Bunker underneath would remain to cause problems for the men of 2PARA. after the initial attempt to seize the far side of Arnhem bridge was repulsed by fire from the bunker a second attempt would be made that night with support of a flame thrower. climbing to the attic of an adjacent house engineers hacked a loop hole through the end wall in order to use the flame thrower. firing on the bunker they hit an ammunition shed beside it neutralizing the bunker but igniting the fresh paint on the bridge preventing further action to seize the bridge.
