I was playing the Red Devils Over Arnhem scenario (Steam version) this evening. When this weird thing happened on D3 on my final attempt to push towards the Arnhem bridge, some of my units were retreating. And (ironically) 2nd battalion HQ (Frost) was retreating...towards the enemy.. through enemy units, straight across the bridge and bending to the other side of the river. Like they were ghosts in a rapidly pace. And the Germans did nothing either. 22 men including Frost retreated right across the main bridge and the Germans were happy with it.
