On 17th April, the Irish Brigade took up the running from 11 Brigade: "The London Irish were to go over at 0400 hrs the next morning in their ‘Kangaroos’ and “marry up” with 9 Lancers on the north of the Reno. Brigade Headquarters opened up that evening about 3,000 yards east of Bastia. The Brigade, less the London Irish, concentrated just to the north. The plan was for us to pass through the Lancashire Fusiliers, as soon as they had secured their bridgehead over the Fossa Marina. These obstacles were the largest canal that ran from Argenta in a north westerly direction across our front. It was the main obstacle in the area. The Faughs were to go first and advance in a north westerly direction; the Skins were to follow them and swing west. Zero hour was to be first light on the 17th. Each battalion had its squadron of tanks and normal supporting arms. The whole move was designed to outflank the town of Argenta on the east and then cut Route 16 north of it. The plan, if successful, would seal off the town and open a way through the gap. The Argenta Gap was no ordinary problem. It was flanked on the left by the river Reno and on the right by flooded low lying country and the Comacchio lake. The enemy was determined to prevent all attempts to break through this Gap of a little over 4,000 yards wide. Another gap in the floods about 1,000 yards wide existed further east by the Strada dell Pioppi and, in that area, 56th Division were smashing their way through against stubborn resistance..."
