on the right, 5th battalion wiltshire regiment began crossing at 19.00 on 25 august in eight storm boats manned by 583 field company, but they grounded before reaching the far side, and were raked by machine gun fire, incurring heavy casualties among boat crews and passengers. by the end of an hour only one boat remained. only about a company had got across, and they were overrun during the night. three of the four available dukws also grounded, the survivor ferrying across the rest of 5th wiltshire in the dark. on the left, 4th battalion somerset light infantry got across in the storm boats relatively easily, but found that their bridgehead was on an island, and they were still cut off from the east bank.
