HMS K1 (Paperback)

High Quality Content by WIKIPEDIA articles! HMS K1 was a First World War steam turbine-propelled K-class submarine of the Royal Navy. She was sunk to prevent her from being captured following a collision with K4 off the Danish coast. She had been patrolling on the surface as part of a flotilla of submarines operating in line ahead. The flotilla was led by the light cruiser Blonde, followed by K1, K3, K4, and K7. Blonde turned sharply to avoid three cruisers which crossed her bows from starboard to port, which caused confusion amongst the following submarines and in the manoeuvring seawater poured into the boiler room through the funnels and put the boiler fires out (a common problem in K-class submarines).
