About 500 men, according to his dispatch, were detailed for the enterprise, but the number appears to have been larger.[141] It was a mixed body. There was a strong contingent of Germans, chiefly dismounted dragoons, ill suited for a cross-country march, and there were also picked marksmen from the British regiments, Canadians, provincials, and about 100 Indians. Out of compliment to Riedesel, the command was given to Colonel Baum, one of his officers, and in selecting German troops for the expedition, Burgoyne marked his appreciation of the good service which those regiments had rendered in following up the retreat of the Americans from Ticonderoga. The starting-point was the Batten Kill stream, running into the Hudson on its eastern side, ten miles lower down than Fort Edward. From this point to Bennington, by the route which Baum was finally instructed to take, was a distance of under thirty miles. The advance guard of Burgoyne’s army had already been moved down the Hudson to the Batten Kill, and, on the 14th of August, after Baum had started, they were thrown across the main river a little higher up under the command of General Fraser, and moved forward on the western bank as far as Saratoga, with the object of a further advance to Stillwater in the event of Baum’s expedition proving successful. The temporary bridge of rafts, however, by which they had crossed, being carried away, the troops were recalled and passed back in boats to the eastern side.
