Moore, Parker, Nichols, and a few others, at the fort until 4.15 a. m. on the 4th instant, when I superintended personally the destruction of the casemates, commissary, guns, &c., by fire and explosion.

I am, very respectfully, your obedient servant,

GEO. WM. LOGAN,

Lieutenant-Colonel, Commanding Garrison, Fort Beauregard.

Respectfully forwarded. Lieutenant-Colonel Logan, having reached this point, was ordered to send in report direct. It has not passed through Brigadier-General Hebert, and I am therefore not yet aware what orders were issued by that officer.

All the heavy guns and one brass field piece have been left in the fort by the enemy, also caissons and other property, to secure and bring off which steps are now being taken. Having no duty to assign Colonel Logan to, I have ordered him to report to the lieutenant-general commanding.
