09-07-1929 : HMS L12 was at sea with an Officer Training Class; at the same time H47 was on independent exercises in the Irish Sea. At 0800 both submarines were off the Pembrokeshire coast with L12 ahead of H47. L12 suddenly altered course to starboard. H47 at once went full astern and to collision stations. The two submarines crashed together with L21 bow penetrating about 2 feet. In only 15 seconds H47 began to sink. L12 also began to take in water but her crew managed to control the flood.
