The French battleship concentrates on the British heavy cruisers because their long-range guns make them the ships most likely to damage it. That choice is judged sensible even though other targets may look larger or more prestigious. The decision ranks threats by their ability to change the current fight. Under fire, the most valuable target is the one that can hurt you now.

A French battleship sensibly directs long-range fire at the heavy cruisers most capable of damaging it, rather than simply shooting at the largest available target.
