Gallipoli might have developed differently if troops and monitors had been available from the outset. Even then, success could have required accepting heavier losses and modifying pre-dreadnoughts with bulges, sealed compartments, or added buoyancy so they could survive mine damage. The broader conclusion is that armies and navies can achieve more when they work to one strategy, while either service acting alone can become trapped by problems it cannot solve. The monitors themselves performed their assigned work, but histories focused on the campaign's failed passages and insufficiently prepared landings can hide that limited operational success.
