A new weapon does not remain an exclusive advantage when an opponent can adopt it too. Larger ships could mount rapid-firing guns while carrying armour against shell damage. Their greater displacement made that protection easier to accommodate. A mixed force could combine the potential range and steadiness of large gun platforms with its own smaller vessels, confronting the French flotilla with capabilities that a force of small ships alone lacked.

Shared weapons undercut the small-ship advantage
New weapons did not belong exclusively to France: larger ships could acquire rapid-fire guns, armour, and the means to counter flotillas.
