Goodrich’s Brigade was detached from its Division, when east of Joseph Poffenberger’s, and ordered to the assistance of Doubleday’s Division. It crossed the Hagerstwon Pike near Miller’s, formed in the north part of the West Woods and on the open ground east of them and, supported by Patrick’s Brigade, advanced in the direction of the Dunkard Church. When nearing this point it was stubbornly resisted by the enemy posted in the woods immediately southwest of this, and Colonel Goodrich was mortally wounded. The loss in the Brigade was heavy and it was obliged to retire.
