On the morning of October 4, 1862, five Union warships under Commander William B. Renshaw approached Galveston Harbor with orders from Admiral David Farragut to capture the port if practicable. A single vessel, the sidewheel steamer Harriet Lane, entered Galveston Bay under a white flag to discuss surrender terms. But the Confederate garrison could not find a boat to send a delegation.

What followed was a chain of miscommunications, a warning shot misread as hostility, cannon fire exchanged while truce flags still flew, and a verbal ceasefire agreement that each side interpreted differently. Nobody died. And the Confederates walked out of Galveston with every cannon they could carry.
