Isle of Hope: Three light batteries. Effective total, 176 men. In addition to their duties attending to their animals and batteries, this force has heavy picket duty to perform, and has charge of two heavy batteries.

Rose Dew: Two companies Cobb Guards (135 effective total) have charge of three heavy batteries, and pickets the coast, &c.

Beaulieu: Hanleiter's light artillery and two companies Twenty-seventh Georgia Battalion. Effective total, 218. This force pickets the coast, has charge of heavy batteries and light artillery company horses.

Fort McAllister: Brooks' light battery and Company A, Twenty-seventh Georgia Battalion. Effective total, 93 men. They have charge of heavy battery, and picket the Ogeechee bridge, 9 miles off, and the coast below the fort. First Georgia Regulars, 238 effective men, are in charge of the Federal officers.

Oglethorpe Barracks: Three companies reserves, 145. This force guards the city and barracks, store-houses; furnishes patrols and train guards.

White Bluff: Guerard's light artillery, 93 effective men. This force, in addition to its battery duties, pickets the river above and below the Water Witch, which it protects, the navy doing nothing toward it.

With this statement you can perceive the very mixed force under my orders guarding the approaches to Savannah and the impossibility of sending any portion away.
