Several men of war and two or three transports, sailed last week from Boston, where they were bound was not certainly known, but it is conjectured they are gone in search of fresh provisions.

Last Sunday [July 30] an express arrived from Suffolk County, on Long-Island with information that a number of transports, with a considerable body of troops from Boston, under convoy of five ships of war, had appeared off Montock Point; that an officer landed, and requested to purchase a number of cattle and sheep, which was refused.

By a return express who left the Camp at Cambridge, last Friday evening [July 28], we are informed that 6 sail of transports sailed from Boston, under convoy of a man of war, some time ago, for the Eastward of Casco-Bay, for forage; that they landed a number of men for that purpose: ー That while the men from the ships were landed, a number of men from the shore possessed themselves of 5 of the ships, made the seamen and soldiers prisoners, and secured the ships out of reach of the man of war.
