This circumstance, that two English frigates had penetrated the very Bay of Mobile five days after, and the news that the detachment of the village had been attacked, moved Dn. Bernardo de Galvez to urge, that although the state of things did not permit a renewal of the expedition from Havana, some troops be given him with which to reinforce the garrisons of Louisiana and Mobile and from there, if a favorable opportunity were found, pledge the inhabitants of those regions to a further effort and fall on Pensacola, or if this could not be, preserve more securely what had been conquered.
