Driven to the necessity of defensive warfare, those in command on the river determined to establish a magazine and garrison at Hadley. Captain Lathrop, who had been despatched from the eastward to the assistance of the river towns, was sent with eighty men, the flower of the youth of Essex county, to guard the wagons intended to convey to Hadley three thousand bushels of unthreshed wheat, the produce of the fertile Deerfield meadows. Just before arriving at Deerfield, near a small stream still known as Bloody Brook, under the shadow of the abrupt conical Sugar Loaf, the southern termination of the Deerfield Mountain, Lathrop fell into an ambush, and, after a brave resistance, perished there with all his company. Captain Moseley, stationed at Deerfield, marched to his assistance, but arrived too late to help him. Deerfield was abandoned, and burned by the Indians. Springfield, about the same time, was set on fire, but was partially saved by the arrival, with troops from Connecticut, of Major Treat, successor to the lately deceased Mason in the chief command of the Connecticut forces. An attack on Hatfield was vigorously repelled by the garrison. Meanwhile, hostilities were spreading; the Indians on the Merrimac began to attack the towns in their vicinity; and the whole of Massachusetts was soon in the utmost alarm. Except in the immediate neighborhood of Boston, the country still remained an immense forest, dotted by a few openings. The frontier settlements could not be defended against a foe familiar with localities, scattered in small parties, skilful in concealment, and watching with patience for some unguarded or favorable moment. Those settlements were mostly broken up, and the inhabitants, retiring toward Boston, spread everywhere dread and intense hatred of "the bloody heathen." Even the praying Indians and the small dependent and tributary tribes became objects of suspicion and terror. They had been employed at first as scouts and auxiliaries, and to good advantage; but some few, less confirmed in the faith, having deserted to the enemy, the whole body of them were denounced as traitors. Eliot the apostle, and Gookin, superintendent of the subject Indians, exposed themselves to insults, and even to danger, by their efforts to stem this headlong fury, to which several of the magistrates opposed but a feeble resistance. Troops were sent to break up the praying villages at Mendon, Grafton, and others in that quarter. The Natick Indians, "those poor despised sheep of Christ," as Gookin affectionately calls them, were hurried off to Deer Island, in Boston harbor, where they suffered excessively from a severe winter. A part of the praying Indians of Plymouth colony were confined, in like manner, on the islands in Plymouth harbor.
