Who would replace an injured battlecruiser commander in 1915?

Who would replace David Beatty if he were too badly injured to command the Royal Navy's battlecruiser force in late 1915?

Doveton Sturdee is the likely replacement because the Sea Lords and Jellicoe would need a senior vice admiral with battlecruiser experience, while Churchill was already out of office.

The discussion rejects the idea that the battlecruiser force could remain without a commander while Beatty recovered. The First Sea Lord and the other Sea Lords would make a quick appointment in consultation with Jellicoe. Doveton Sturdee is identified as the likely senior vice admiral with relevant battlecruiser experience and therefore the strongest available candidate. Churchill would not control the choice because he had resigned as First Lord in November 1915. The closing aside adds that Churchill was in France by 1916 and could meddle only so far in the naval command structure.
