Most of the German brigade comprised three Hessian regiments: those of Rall, von Lossberg, and von Knyphausen. The remainder of the brigade consisted of artillery corps attached to each regiment, a detachment of Jäger, and a small company of British dragoons. The attacking American army consisted of units from the Continental Army, including companies of its artillery, and a few companies of militia. Additional units were intended to also participate either in the attack, or in diversions to draw attention from the main thrust; these units failed to cross the icy Delaware River and did not participate in the action.
