"Thompson"’s smaller guns also got into the fray. Her 40 mm batteries shredded concealments of shore batteries and sniper nests, working in close conjunction with shore spotting teams who ferreted out the hidden enemy. Among her other targets was a fortified house. Solidly constructed, it had withstood numerous coastal storms. But on 6 June 1944, its solid Norman masonry could not hold up to a few rounds of five-inch (127 mm) high explosives; and down it tumbled, into a pile of rubble.
