56th Division was next tasked with capturing a bridgehead across the Garigliano using strong artillery support (400 rounds per gun were supplied for the division's 25-pounders). The attack on the night of 17/18 January 1944 was successful and by morning the leading battalions were across and attacking with plenty of artillery support. The division began its breakout from the bridgehead on 23 January, but at the end of the month was ordered to pull out and go by sea to reinforce the Anzio beachhead. By 15 February the whole division had arrived and taken over part of the line under US VI Corps, in time to beat off the German counter-attack ("Operation Fischfang" or 'Catching Fish').
