The Light-cruiser HMS Blonde was leading K1, K3, K4 and K7 in line ahead when she was forced to turn sharply to port to avoid three cruisers, that crossed her bows from starboard to port. The abrupt change of course took the submarines by surprise and K1 and K4 collided. K1 had lost way due to salt-water, instead of fuel, coming through the sprayers and extinguishing the boilers. K3 passed close on the port side. K4, following K3, suddenly observed the red light of K1, and, although taking avoiding action, struck K1 a glancing blow abreast the conning tower. Water poured into the control room. Within minutes, chlorine gas was being released from the batteries. Blonde was signalled that K1 was sinking, and the cruiser closed, lowering two cutters. The rescue boats made five trips and transferred all 56 members of the crew to Blonde. A discussion was then held as to whether K1 could be saved, and it was decided to sink her.
