The preceding is endorsed, in the handwriting of General Montgomery, on the back of Mr. Duane's letter.
The laxity of the discipline which pervaded the camp at Cambridge, the inexperience of the officers, and the contests and petty squabbles about rank, all tended to excite great jealousy and discontent in the army. As yet, Burr was attached to no particular corps. He mingled indiscriminately with conflicting factions, until, disgusted with the scene which he daily witnessed, he was violently attacked with a nervous fever, by which he was confined to his bed.
One day he heard Ogden and some young men of the army conversing, in an apartment adjoining that in which he was lying, on the subject of an expedition. He called Ogden to his bedside, and inquired what was the nature of the expedition of which they were speaking. Ogden informed him that Colonel Arnold, with a detachment of ten or twelve hundred men, was about to proceed through the wilderness for the purpose of attacking Quebec. Burr instantly raised himself up in the bed, and declared that he would accompany them; and, so pertinacious was he on this point, that he immediately, although much enfeebled, commenced dressing himself. Ogden expostulated, and spoke of his debilitated state--referred to the hardships and privations that he must necessarily endure on such a march, &c. But all was unavailing. Young Burr was determined, and was immoveable. He forthwith selected four or five hale, hearty fellows, to whom he proposed that they should form a mess, and unite their destiny on the expedition through the wilderness. To this arrangement they cheerfully acceded. His friend Ogden, and others of his acquaintance, were conveyed in carriages from Cambridge to Newburyport, distant about sixty miles; but Burr, with his new associates in arms, on the 14th of September, 1775, shouldered their muskets, took their knapsacks upon their backs, and marched to the place of embarcation.
I was infinitely surprised to hear from you in the army. I can hardly tell you what sensations I did not feel at the time. Shall not attempt to describe them, though they deprived me of a night's sleep. But that was not spent altogether unhappily. My busybody, _Fancy_, led me a most romantic chase; in which, you may be sure, I visited your tent; beheld you (unnoticed) musing on your present circumstances, apparently agitated by every emotion which would naturally fill the heart of one who has come to the resolution to risk his life for his country's freedom. You will excuse my mentioning, that from a deep, absent meditation, partly expressed by half-pronounced soliloquies, I beheld you start up, clap your hand upon your sword, and look so fiercely, that it almost frightened me. The scene, on your discovering me, immediately changed to something more tender; but I won't waste paper.
