Letter written in code and translated in which Benedict Arnold describes his terms ($20,000) for becoming a traitor and revealing vital information about troops and equipment at West Point, July 15, 1780.
Inclosed in a cover addressed to M[r.] Anderson Two days since I received a letter without date or Signature, informing me that S[ir]. Henry ------ was obliged to me for intelligence communicated, and that he placed a full confidence in the Sincerity of my intentions, etc. etc. On the 13th Instant I addressed a letter to you expressing my Sentiments and expectations, viz, that the following Preliminaries be settled previous to cooperating. - First, that S[ir]. Henry secure to me my property, valued at ten thou- sand pounds Sterling, to be paid to me or my Heirs in case of Loss; and, as soon as that happens [strike out] shall happen, ---- hundred pounds per annum to be secured to me for life, in lieu of the pay and emoluments I give up, for my Services as they shall deserve - If I point out a plan of cooperation by which S[ir}. H[enry]. shall possess himself of West Point, the Garrison, etc. etc. etc. twenty thousand pounds Sterling I think will be a cheap purchase for an object of so much importance. At the same time I request thousand pounds to be paid my Agent - I expect a full and explicit answer - The 20th I set off for West Point. A personal interview with an officer that you can confide in is absolutely necessary to plan matters. In the mean time I shall communicate to our mutual Friend S[tansbur]y all the intelligence in my power, until I have the pleasure of your answer.
Moore July 15th  To the line of my letter of the 13th I did not add seven.
