If Hood survived a secondary-magazine explosion

If flooding contained a 4-inch magazine explosion aboard Hood, would Holland have broken off the battle?

Probably: even without catastrophic loss, flooding, turbine and steering damage would likely force Hood out of the battle line while the tactical situation developed.

The scenario assumes water prevents a 4-inch magazine explosion from propagating into Hood's 15-inch magazine, but leaves fire, flooding, turbine damage, and steering problems. Vice-Admiral Holland would likely have to withdraw or at least drop out of the battle line. Hood had several steering positions and auxiliary arrangements, so loss of one system did not automatically mean total loss of control. The decisive questions would be hull damage, flooding, attainable speed, and whether steering could still function reliably. Both fleets would then face choices about continuing the engagement.
