Prior to Maxwell's futile attack against Cliveden, Sullivan's division advanced beyond in the fog. Sullivan deployed Brigadier General Thomas Conway's brigade to the right, and Brigadier General Anthony Wayne's brigade to the left before advancing on the British center-left. The 1st and 2nd Maryland Brigades of Sullivan's column paused frequently to fire volleys into the fog. While the tactic was effective in suppressing enemy opposition, his troops rapidly ran low on ammunition. Wayne's brigade to the left of the road moved ahead, and became precariously separated from Sullivan's main line. As the Americans launched their attack on Cliveden, Wayne's brigade heard the disquieting racket from Knox's artillery pieces to their rear. To their right, the firing from Sullivan's men died down as the Marylanders ran low on ammunition. Wayne's men began to panic in their apparent isolation, and so he ordered them to fall back. Sullivan was subsequently forced back, although the regiments fought a stubborn rear-guard action. Since the British units pursuing them were redirected to fight Greene's column, Sullivan's men fell back in good order.
