However, bringing the Spanish ships into the bay turned out to be difficult, just as it had been the previous year at the capture of Mobile. Supplies were offloaded onto Santa Rosa Island to raise the draft of some of the ships, but Calvo, the fleet commander, refused to send any more ships through the channel after the lead ship, the 64-cannon "San Ramon", grounded in its attempt. Furthermore, some British guns seemed to have the range to fire on the bay's entrance.
