The RWF history does make mention of SS prisoners they captured - whilst doing a large Battalion level push to the enemys rear at night, 4 RWF captured a large number of SS prisoners who were made to dig a series of ditches. The 4 RWF (strongly implied by the text) treated them as if they were about to be shot then thanked them for digging the new Battalion HQ... I want to check this with the war diary
