At 18:21, with both Beatty and the Grand Fleet converging on him, Hood turned south to lead Beatty's battlecruisers. Hipper's battlecruisers were away and the "Invincible"s almost immediately opened fire on Hipper's flagship, , and . "Lützow" quickly took ten hits from , "Inflexible" and "Invincible", including two hits below the waterline forward by "Invincible" that would ultimately doom her. But 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. A 305 mm (12-inch) shell from the third salvo struck the roof of "Invincible"s midships 'Q' turret, flash detonated the magazines below, and the ship blew up and broke in two, killing all but six of her crew of 1,032 officers and men, including Rear-Admiral Hood.
