SIR:--Last evening I received a flag from Major Carleton commanding the British forces at Crown Point, with proposals from General Haldimand, commander-in-chief in Canada, for settling a cartel for the exchange of prisoners. Major Carleton has pledged his faith that no hostilities shall be committed on any posts or scouts within the limits of this state during the negotiation. Lest your state [New York] should suffer an incursion in the interim of time, I have this day dispatched a flag to Major Carleton, requesting that he extend cessation of hostilities on the northern parts and frontiers of New York. You will therefore conduct your affairs as to scouts, &c., only on the defensive until you hear further from me. I am, &c., ETHAN ALLEN. To Colonel Webster. To be communicated to Colonel Williams and the posts on your frontier. He also wrote to Colonel Webster: RUPERT, about break of day of the 31st October, 1780. SIR:--Maj. Ebenezer Allen who commands at Pittsford has sent an express to me at this place, informing me that one of his scouts at 1 or 2 o'clock P.M. on the 29th instant, from Chimney Point, discovered four or five ships and gun-boats and batteaux, the lake covered and black, all making sail to Ticonderoga, skiffs flying to and from the vessels to the batteaux giving orders, and the foregoing quoted from the letter verbatim. But I cannot imagine that Major Carleton will violate his truce. I have sent Major Clarke with a flag to Major Carleton, particularly to confirm the truce on my part, and likewise to intercede in behalf of the frontiers of New York. What the motion of the British may be, or their design, I know not. You must judge for yourself. I send out scouts to further discover the object of the enemy. Maj. [Ebenezer] Allen thinks they have a design against your state. From your humble servant, ETHAN ALLEN. He wrote to the president of Congress: SUNDERLAND, 9 March, 1781.
