Siege of Fort Morgan

Granger's soldiers landed at Pilot Town on August 9 and began moving siege artillery within range. The Union fleet also turned their guns on the fort. For the next two weeks Union forces kept up a heavy and consistent artillery fire. On August 16 the Confederates abandoned two batteries of the outer defenses and Granger moved his siege mortars within 500 yards of the fort and his 30-pounder rifled guns to within 1,200 yards.

On August 23, General Page unconditionally surrendered the fort. Indignant, he broke his sword over his knee instead of surrendering it to the Federals. Page's situation was further worsened when he was suspected of destroying munitions and works within the fort after the surrender agreement. For this he was arrested by the Federal authorities and imprisoned.

The fall of Fort Morgan to the Union forces sealed the mouth of Mobile Bay. The city of Mobile, Alabama would fall on April 12, at the end of the Civil War, after the Battle of Fort Blakeley on April 9, 1865.

General Page remained imprisoned until July. A court of inquiry was convened in New Orleans to investigate the charges against Page for violating the laws of war. The court, however, found him "Not Guilty". The court found that much of the destruction of ammunition resulted from a fire in the Citadel and that Confederates had spiked the artillery pieces before they had raised a white flag of surrender.
