This Union vessel issued a warning that all women and children were to be taken away from the city for an attack would occur in 24 hours. The Confederate soldiers that made up the Key West Avengers and the Osceola Rangers cheered at the prospect of a fight....that never took place as promised. No further Union incursion would take place for a few months. All the while the Union blockade became tighter and tighter.
On June 30th, the Union gunboat, the USS Sagamore was seen two miles offshore. The gunboat promptly began shelling the town before launching a smaller vessel with a flag of truce to meet with the city's commanding officer. The officer of the Sagamore ordered the city to surrender, to which the CSA officer responded that they would not and sent the Union representatives back. For the rest of the day, into the night and in the morning of July 1, both sides fired on each other. In the afternoon of July 1, the Sagamore left. Neither side suffered any known casualties.
A year later, Tampa would be attacked again when Union vessels and a landing party attacked Fort Brooke located in Tampa itself and destroyed several blockade runners hidden along Hillsborough River.
