 After the breakout from the Normandy beachhead, 43rd (W) Division was sent ahead to make an assault crossing of the River Seine at Vernon.US troops had already reached the west bank of the Seine, so the convoys of assault troops and bridging material moving eastwards had to be carefully coordinated to cross with US convoys repositioning to the south.130 Brigade was in Group 3, a convoy of just over 1000 vehicles including 15th (Kent) GHQ Troops Royal Engineers who were to operate tank rafts and build a heavy Bailey Bridge.
