"Royal Oak" quickly listed to 15°, sufficient to push the open starboard-side portholes below the waterline. She soon rolled further onto her side to 45°, hanging there for several minutes before disappearing beneath the surface at 01:29, 13 minutes after Prien's second strike. 835 men died with the ship or died later of their wounds. The dead included Rear-Admiral Henry Blagrove, commander of the Second Battle Squadron. 134 of the dead were boy seamen, not yet 18 years old, the largest ever such loss in a single Royal Navy action. The admiral's wooden gig, moored alongside, was dragged down with "Royal Oak". The tender "Daisy 2", skippered by John Gatt, had been tied up for the night to "Royal Oak"s port side. As the sinking battleship began to list to starboard, Gatt ordered "Daisy 2" to be cut loose, his vessel becoming briefly caught on "Royal Oak"s rising anti-torpedo bulge and lifted from the sea before freeing herself. Many of "Royal Oak"s crew who had managed to jump from the sinking ship were dressed in little more than their nightclothes and were unprepared for the chilling water. A thick layer of fuel oil coated the surface, filling men's lungs and stomachs and hampering their efforts to swim. Of those who attempted the half-mile (800 m) swim to the nearest shore, only a handful survived. "Royal Oak"s port side pinnace was manoeuvred away from the sinking ship and paddled away using wooden boards as there had been insufficient time to raise steam. The boat became overladen and capsized 300 metres from "Royal Oak", throwing those on deck into the water and trapping those below. Gatt switched the lights of "Daisy 2" on and he and his crew managed to pull 386 men from the water, including "Royal Oak"s commander, Captain William Benn. The rescue efforts continued for another two and a half hours until nearly 4:00 am, when Gatt abandoned the search for more survivors and took those he had to "Pegasus". Aided by boats from "Pegasus" and the harbour, he was responsible for rescuing almost all the survivors, an act for which he was awarded the Distinguished Service Cross, the only military award made by the British in connection with the disaster. "Pegasus" had sent a message by signal lamp to the port signal station about five minutes after the sinking, saying "General.
