The fleet flagship and 1st Battlecruiser Squadron, front HMS Lion (fleet flagship) and HMS Tiger, rear HMS Princess Royal (squadron flagship) and HMS Queen Mary.
The 2nd Battlecruiser Squadron flagship, HMS New Zealand
By 1916, the 2nd Battlecruiser Squadron was very much out of place in a fleet action against anything heavier than cruisers. Even the 1st Battlecruiser Squadron was pretty vulnerable when trading salvos with capital ships. The 5th Battle Squadron provided the muscle that the Battlecruiser Fleet so badly needed.
Thanks for looking!
