hi
My father served with the 8th Battalion 6th Airborne Div, 14436779 D.E.W Harris he landed in Normandy at Troarn, to blow the bridges over the Dives river, he was later sent to re enforce the 9th Battalion as they had took a battering at Merville, so your man may have served with this Battalion ? and I have not heard of a S company, unless it stands for support
