He tried to reach the British pickets at Chestnut Hill before daylight; but the roughness of the roads over which his army marehed prevented, and it was almost sunrise when he emerged from the woods on that elevation. His approach had been discovered at early dawn by the British patrols, who gave the alarm. The troops were soon called to arms, and placed in battle order on Mount Airy, about a mile north of Chew's house in Germantown. At seven o'clock Sullivan's advanced party, drawn chiefly from Conway's brigade, and led by that officer, fell upon the British pickets at Allen's house, at Mount Airy, where they had two six-pounders, and drove them back to the main body near, which consisted chiefly of the fortieth regiment and a battalion of light infantry. Sullivan's main body now left the road, moved to the right through the fields, formed in a lane leading from Allen's house toward the Schuylkill, and joined in the attack with so much vigor and such overwhelming numbers, that the enemy, after a sharp engagement of twenty minutes, gave way, and fell back to the village, closely pursued by the victors. Colonel Musgrave, who commanded the British center, thus furiously attacked, threw himself, with five companies of the fortieth regiment, into Judge Chew's large stone house, pictured on page 314, from which such a severe discharge of musketry was poured upon Woodford's brigade, which was * Sparks, v., 78. [[[Scenes at Chew's House.--Remissness of the Militia.--Victory lost to the Americans.]]] {317}pursuing the flying enemy, that their progress was checked. The fire of the small arms of the patriots upon this refuge was quite ineffectual. General Reed, it is said, proposed to continue the pursuit of the remainder of the enemy, who were then in great confusion, and turning their faces toward Philadelphia; but General Knox, of the artillery, opposed the suggestion, as being against all military rule "to leave an enemy in a fort in the rear. "What!" exclaimed Reed, "call this a fort, and lose the happy moment!" They sought for Conway to decide the point, but he was not to be found. Knox's opinion prevailed, and pursuit was abandoned. A flag was now sent by a young man * to demand a formal and immediate surrender. The bearer was slain by a bullet when within musket-shot of the house. Cannons were now brought to bear upon the house by the artillery regiment of Maxwell s brigade; but so strong were the walls and so courageous were the inmates, that it was found impossible to dislodge them. Attempts were made to set the house on fire, but without success. ** Many of the Americans were killed in the assault, while scarcely a man of the garrison was wounded. The attempt to dislodge the enemy caused many of the American troops to halt, and brought back Wayne's division, which had advanced far beyond the house. This totally uncovered Sullivan's left flank, which was advancing toward the enemy's left, and disconcerted all their plans.
