Would High Seas Fleet ships strike their colours?

Could any High Seas Fleet ships strike their colours during the alternate battle?

Possibly, but probably few; a confused close-range fleet action would destroy many ships before an orderly surrender could be made.

The projected close-range breakout would leave little time or safety for an orderly surrender. German ships might try to strike their colours, but the fighting would be confused and their losses would come quickly. The possibility cannot be excluded, though most disabled ships would probably be destroyed before their crews could surrender. This remains a conditional outcome of the imagined battle rather than a claim about the historical High Seas Fleet.
