Since ours to you, by return of the packet from New Hampshire, and duplicates by Mr McCreary, from Maryland, we have not written, nor have we received any of your favors during the last two months, except a letter of old date, (April 19th) signed by Messrs Deane and Lee. Captain Hammond being not yet arrived, although he sailed in April, it is too probable that he has fallen into the enemy's hands, or miscarried at sea. Two reasons have prevented us from writing hitherto; because from your assurances we had cause to expect a monthly packet, and because the progressive state of the war gave us reason to look for some more decisive event daily, than had happened, and which might warrant the expense of sending a particular packet, as the casual conveyance by merchant vessels is almost entirely stopped by the number and vigilance of the enemy's cruisers. We shall now give you an accurate detail of the war in the northern and middle departments, where alone it has raged since our last. You were before apprized of the evacuation of Ticonderoga, and of the retreat of our army from thence towards Albany. General Burgoyne was rapid in pursuit of his successes, and pressed quickly on towards fort Edward, upon Hudson's river, about twenty miles above Albany. Here his progress was interrupted by the American army, being halted and reinforced a little below him. This circumstance, with the following events, have continued that interruption, and bid fair to render abortive, at least, the great advantages expected by our enemies from their first successes on the lakes.
