The troops embarked at Hartford on the 10th of May, and sailed down the river to Saybrook. They consisted of ninety Englishmen, and about seventy Mohegans and river Indians. While at Saybrook, forty of the Indians under Mason, being out at some distance from the place, fell in with about forty of the enemy, killed seven and captured one, who was brought to the fort, and executed by the English. Here the little army was joined by Captain Underhill with nineteen men, who had some months before been sent by the governor of Massachusetts to strengthen the garrison at Saybrook. This accession to his forces permitted Mason to send back twenty of his original number for the protection of the infant settlements on the river, which were peculiarly exposed at this crisis. The whole force, including the Indians, was embodied and directed by Mason. After remaining several days at Saybrook to complete his arrangements, he sailed, with his Connecticut forces, for Narraganset bay, where he arrived on the 19th of May. At this place, two hundred of Miantonimoh's warriors were engaged to accompany the English forces on the expedition. Information was now received from Captain Patrick, that he had arrived at Providence with forty Massachusetts' men, under orders to join the troops of Connecticut. For various reasons, but chiefly from an apprehension that the Pequods might gain intelligence of the expedition, Mason commenced his march, without waiting for Patrick's company, and soon reached Nehantick, the seat of the Narraganset sachems. Here he was joined by an additional company of Indians--the whole army, including the English, amounting to more than five hundred. Here they staid over night, and learning that the Pequods held two forts, one at Mystic river and the other about three miles west of that, they resolved, contrary to their original plan of attacking both together, to make a united attack on the Mystic fort, and accordingly commenced their march. After a march of twelve miles, through forests and over hills and morasses, Mason reached the Pawcatuck. The day was very hot, and the men, through the great heat and a scarcity of provisions, began to faint. Here he halted for some time, and refreshed the troops. In the meanwhile, the Indians, who had previously boasted how they would fight, when they learned that the forts were to be actually attacked, and the dreaded Sassacus to be met, were overcome by their fears, and many of them returned home to Narraganset. But the intrepid Mason, resolving to advance, despatched a faithful Indian to reconnoitre the fort, who soon returned with information that the Pequods were unapprised of their danger, and appeared to be resting in entire security. The march was immediately rëcommenced towards Mystic river, and on the night of the 26th, the whole body encamped about three miles from the fort.
