A temporary truce between the two opposing sides was established, and despite still being outnumbered, the Confederate forces sent over an officer to negotiate terms of surrender of the Union fleet.

Union troops on shore were convinced that their own ships were surrendering and, therefore, laid down their arms. The remaining U.S. ships did not surrender and succeeded in retreating to Union-controlled
New Orleans. ==Aftermath==
