No. 9 commando were landed on the north shore of the estuary by the Royal Navy during the night of 29/30 December 1944. Unfortunately they were 95 minutes late and away from their correct landing beach. The commando attacked several German positions before withdrawing across the river in DUKWs, apart from No.4 and No.6 troops who had to cross upriver by using ropes and swimming. The operation cost the commando nine killed but they did capture 29 prisoners.
