s and eventually
K14s helm was freed and she tried to return to her position in the line. The next submarine in line, K22 had lost sight of the rest of the flotilla in the mist and veered off the line with the result that she hit K14. Both submarines stopped whilst the rest of the flotilla, unaware of what had happened continued out to sea. K22 radioed in code to the cruiser leading the flotilla to say that she could reach port but that K14 was crippled and sinking.

About fifteen minutes later, the 2nd Battlecruiser Squadron passed the island and the two submarines, but the battlecruiser
Inflexible hit K22 causing further damage. The battlecruiser bent the first 30 feet of K22s bows at right angles, and wrecked the ballast and fuel tanks. She settled by the bow until only the conning tower

As the submarines behind her turned to follow her, the 2nd Battle Squadron passed through the line, and it was only through emergency turns by both groups of vessels that further accidents were narrowly avoided.

As the 13th Flotilla reached the Isle of May, they encountered the outbound 12th Submarine Flotilla. The leader of the 12th Flotilla, Fearless loomed out of the mist and collided with K17 which sank within a few minutes, although most of her crew were able to jump overboard.

, the battlecruiser Australia narrowly missed K12 which turned to get out of the way, putting her on a collision path with K6. K6 tried to avoid her but in doing so hit K4, nearly cutting the latter in half. The seriously damaged K4 sank with all of her crew, during which she was hit by K7.

At this point the 5th Battle Squadron of three battleships and their destroyers passed through the area unaware of what had happened, some of the destroyers cutting down the survivors of K17 struggling in the water. Only nine of the 56 men originally on board the submarine survived and one of these died of his injuries shortly afterwards.

Within 75 minutes, the submarines K17 and K4 had been sunk, and K6, K7, K14, K22 and Fearless had been damaged and over a hundred people killed on the night, with a total loss of 270 persons altogether, including those later dying of wounds.
