At Jig, the first wave of infantry (the 1st Dorsetshires and 1st Hampshires of the 231st Infantry Brigade) arrived at 07:25, and immediately came under fire from the casemated 75 mm gun at Le Hamel. Due to navigation errors and the strong current, both groups came ashore well to the east of their intended landing points. The DD tank and Royal Marine Centaur tanks that were supposed to arrive in advance of the landing were delayed by rough seas and did not arrive until 08:00. Many of the tanks got bogged down on the beach or were taken out by enemy fire. The tide came in quicker than expected, before many of the beach obstacles and mines were cleared, and some of the landing craft were damaged as a result.
