Eventual Fate
–
Jutland result
Around 18:20 when the Grand Fleet was deploying, the BCF was roughly 9,000 yards from Hipper's SG. Indominatable hit Derfflinger three times, Seydlitz once. About 20:19, Inflexible and Indomitable spotted the SG around 10,000 yards off as the sun was setting. Seydlitz was hit 5 times before Mauve's pre-dreadnoughts joined. Three of his ships were then hit when the two British battle-cruisers shifted fire to the larger and new threat.
