Major Willard soon left the region of Brookfield, and marched the principal part of his forces to Hadley, for the protection of the settlements in that quarter. When he had completed his business, he returned to Boston, leaving Lathrop and Beers at Hadley. A considerable number of christianized Indians, belonging to the neighborhood of Hadley, occupied a small fort about a mile above Hatfield. On the occurrence of the difficulties in that region, these, as all other Indians, were watched and suspected of conniving with Philip. To put their fidelity to a test, Captains Lathrop and Beers, with a force of one hundred and eighty men, ordered these Indians to surrender their arms. They hesitated to do so then, but promised a speedy compliance. Yet, on the following night, August 25th, they left their fort, and fled up the river towards Deerfield to join Philip. The English captains commenced a pursuit early the next morning, and came up with them at a swamp, opposite to the present town of Sunderland, where a warm contest ensued. The Indians fought bravely, but were finally routed, with a loss of twenty-six of their number. The whites lost ten men. The Indians, who escaped, joined Philip's forces, and Lathrop and Beers returned to their station in Hadley. [Illustration: Battle of Muddy Brook.] Near the middle of September, Captain Lathrop was sent from Hadley, with eighty-eight men, to bring away some corn, grain, and other valuable articles from Deerfield. It was at that very time that the company under Captain Mosely, then quartered at Deerfield, intended to pursue the enemy. But upon the 10th of the month, "that most fatal day, the saddest that ever befel New England," Lathrop's company was attacked by the Indians, who had selected a place very advantageous to their purpose, knowing that the English with their teams would pass the road at the spot. The place was at the village now called Muddy Brook, in the southerly part of Deerfield, where the road crossed a small stream (as it now does), bordered by a narrow morass. Here the Indians, in great force, had planted themselves in ambuscade; and no sooner had Lathrop arrived at the spot, than the Indians poured a heavy and destructive fire upon the columns, and then rushed furiously to close engagement. The English ranks were broken, and the scattered troops were every where attacked. Those who survived, after the first onset, met the foe individually, and endeavored to sell their lives as dearly as possible. Seeking the covert of a tree, each one selected an object of attack, and the awful conflict now became a trial of skill in sharp shooting, on the issues of which life or death was suspended. But the overwhelming superiority of the Indians, as to numbers, left no room for hope on the part of the English. They were cut down every instant from behind their retreats, until nearly the whole number were destroyed. The dead, the dying, the wounded, strewed the ground in every direction.
