As they neared Fort Gibson, a Confederate artillery battery guarding the Sabine Pass, Crocker ordered his fleet of two schooners and a steamship to begin an artillery bombardment of the enemy position. Confederate forces numbering 30 infantry and artillerists, additionally supported by 30 cavalrymen, were unable to return fire as the outdated garrison's batteries were unable to reach the Union fleet. The commanding officer, Major J. S. Irvine, ordered his artillery spiked and then retreated during the night. Without a significant military presence, the town of Sabine Pass, Texas, surrendered the following day.
