About eleven o'clock on the morning of the 19th, Burgoyne's army advanced in three columns. He, in person, in command of the centre column, moved towards Freeman's Farm, opposite to the American left; Riedesel and Phillips with a large train of artillery, forming the left column, followed the river road, and, after the attack had begun, turned westward to support and prolong the line of battle of the deployed centre; while, by a circuitous march, Fraser, with Breyman's German riflemen, having his flanks covered by Canadians, loyalists, and Indians, moved with the right column, taking post westward of the centre, thus greatly overlapping the American left, which it was designed to turn and rout.
Gates, called by Burgoyne "an old midwife", impassively looked on, giving no orders and evincing no desire to fight, while the impatient Arnold, foreseeing the enemy's movement to turn his left, sent Morgan's riflemen and some of Dearborn's light infantry to check it. They rushed upon the enemy, and dispersed the Canadians and Indians; but following up their success too eagerly, they soon encountered the British line of battle, and were overpowered by superior numbers. This being reported to Gates, the Continental troops were sent to support Morgan, but the entire force proved insufficient to cope with and counteract Fraser's movement. Arnold, undismayed, then changed his direction, and fell suddenly upon the enemy's centre with a view of separating Burgoyne from Fraser. The battle was waged with great fury by both antagonists, and as each received reinforcements the conflict deepened, and, with varying success, became more and more stubborn. Burgoyne finally escaped defeat by the timely coming up of Riedesel with Pausch's artillery. After this death-struggle of four hours' duration, darkness terminated the contest. The Americans fell back in good order to their intrenchments, while the Anglo-German army, lying on their arms, retained the barren field of their foiled efforts to advance. Though both sides claimed the victory, neither had triumphed at "Freeman's Farm." It was in reality a drawn battle. The forces engaged in the conflict were nearly equal, the Americans having about 3,000 and the enemy nearly 3,500 of their best troops. The loss of the former was 65 killed, 218 wounded, and 38 missing; while that of the latter, according to their own authorities, was about 600 killed and wounded. British bayonets and abundant artillery were fully matched by American rifles, without a single piece of ordnance. Had Arnold been properly reinforced by Gates, he might have broken the enemy's line and have gained a complete victory.
