HMS H47, a small British submarine on a routine exercise, was running on the surface when the larger HMS L12 — also British, also on exercise — came round on her starboard side and struck her amidships. H47 began to flood at once. Twenty-one of her twenty-two crew were trapped below as she went down. Only three men reached the surface alive, and one of those did not survive his injuries.

Each disaster — H47 in 1929, M2 in 1932, Thetis in 1939 — forced the Royal Navy to redesign hatches, develop escape apparatus, change exercise procedures. After H47, surface-to-surface signalling protocols between exercising submarines ...

The waters where she lies are unmarked at the surface. Fishing boats and ferries pass over the wreck regularly without knowing it is there.
