Hipper's battlecruisers were away and the "Invincible"s almost immediately opened fire on Hipper's flagship and . "Indomitable" hit "Derfflinger" three times and "Seydlitz" once, while the "Lützow" quickly took 10 hits from , "Inflexible" and "Invincible", including two hits below the waterline forward by "Invincible" that would ultimately doom her. At 18:30 "Invincible" abruptly appeared as a clear target before "Lützow" and "Derfflinger". The two German ships then fired three salvoes each at "Invincible" and sank her in 90 seconds. At least one 305 mm (12-inch) shell from the third salvo struck her midships 'Q' turret. The shell penetrated the front of 'Q' turret, blew off the roof and detonated the midships magazines, which blew the ship in half. The explosion possibly ignited 'A' and 'X' magazines. Of her complement, 1026 officers and men were killed, including Rear-Admiral Hood. There were only six survivors picked up by . Five of the six were stationed in the fire-control top located on the tripod foremast; the other man was stationed in 'Q' turret itself. When the magazine exploded he was somehow thrown clear of the ship.
