Colonel Dearborn was born in Hampton, N.H., in March, 1751. He was a captain at Bunker Hill, and accompanied Arnold in the march through the woods against Quebec, in which expedition he was captured. He was exchanged in 1777, and soon after was appointed Major of Scammel's regiment. At Saratoga he commanded a separate battalion under General Gates, and was afterwards at Monmouth, where he distinguished himself and the regiment by a gallant charge. In 1779 Colonel Scammel was acting as Adjutant General of the army, leaving Lieut. Colonel Dearborn in command of the regiment during Sullivan's campaign. He was at the siege of Yorktown in 1781, and afterward on garrison duty at Saratoga and West Point until 1784. He served two terms in Congress, was for eight years secretary of war under Jefferson, and in the war of 1812 was senior Major General of the army. In 1822 he was minister to Portugal, from whence he returned after two years' service, and died in Roxbury, Mass., June 6, 1829. After his death, his son, Henry Alexander Scammel Dearborn, collected and arranged the valuable papers of his father, transcribed the journals, which extended through the entire period of the revolution, and added important historical sketches, the whole making forty-five large volumes handsomely bound in morocco, the exterior approximating in elegance to the inestimable value of the material within. On the death of the son, all of these, excepting seven volumes, were taken apart, and the contents, made up of valuable autograph letters of the revolutionary period, scattered to the four winds by a sale at public auction. The original manuscript Journal of Sullivan's campaign fell into the hands of Dr. John H.S. Fogg, of Boston. The manuscript Orderly Book of Valley Forge, was purchased by John H. Osborne, Esq., of Auburn. The seven volumes, containing no autographs, were reserved at the sale and remain intact In one of these is the Journal kept during Sullivan's campaign, as transcribed by the son, of which the following is an extract: PART OF COLONEL DEARBORN'S JOURNAL, 1779.
