My casualties are as follows: April 5.--One private of the Seventh Maine, and one of the Forty-ninth New-York killed, and two privates of the Seventh Maine, and one of the Forty-ninth New-York wounded. April 6.--Three privates of the Forty-ninth New-York wounded severely; one officer, Lieut. George Gale, of the Thirty-third New-York, seriously wounded; one of the Seventy-seventh seriously wounded. April 7.--One private of the Seventh Maine seriously wounded; one of the Seventy-seventh seriously wounded. April 8.--One private wounded, Thirty-third New-York volunteers. April 11.--One corporal, Seventh Maine, killed, and one private wounded. The Forty-ninth regiment and a company of the Thirty-third New-York, the latter under command of Lieut.-Col. Corning, were much exposed to the fire of the enemy's rifle-pits while we lay in position. I regret to state that Lieut. Swan, company A, and Bugler Brown, company D, Seventh Maine volunteers, were captured by the enemy on the fifth inst., being separated from their command by a swamp while skirmishing. I desire to bring specially to the notice of the General the cheerfulness, obedience, and fortitude of the regiments of my brigade, lying as they did for fifty-four hours under the close artillery-fire of the enemy, two nights exposed to a violent storm, without an opportunity of exchanging a shot, except from light field-pieces, and bearing — some regiments of it-thirty--six hours duty as skirmishers to the front, and willing for more. I think the general commanding the division may well be proud of them, as I am, and trust to the successful exhibition of their other soldierly qualities when we meet the enemy closer. I have no distinction to make among the regiments of my brigade. The duties of some were necessarily more arduous than those of others, and led them into more exposed positions; but when all behaved alike with the greatest coolness, gallantry, obedience, and fortitude, they are all equally deserving of my warmest gratitude and confidence, and I desire so to present them to the commanding general. I am, Sir, your obedient servant,
J. W. Davidson, Brigadier-General.
