The 'Boston Daily Bee' spoke of the son of Benedict ARNOLD which take place in London. Lt. James Roberston ARNOLD was the oldest of four children which Arnold's second wife, Miss SHIPPEN of Philadelphia bore him, viz. James Robertson, Edward, George and Sophia. His first wife bore him three sons viz., Benedict Richard and Henry. Benedict, the oldest was an officer of artillery in the British Army and, it is believed, was compelled to quit service. He died young in the West Indies. Henry ARNOLD entered the King's Service after his father's defection and was Lt. of Cavalry in the American Legion. He accompanied his father to St. John and was employed in his business. He slept in the warehouse near Lower Cove and lodged there the night the building was burned. He lived afterwards at Troy, N.Y. with his aunt Hannah and was engaged in mercantile pursuits. At a subsequent period he moved to Canada where he is now a man of property. He received half pay and a grant of lands from the British Gov't. In 1783 Richard ARNOLD was a Lt. of calvalry in the American Legion commanded by his father. In most every particular his history is identical with that of his brother Henry. Persons are still living at Saint John who resided there when Arnold's store was burned. The impression was, and still is, the fire was caused by design for the purpose of defrauding a company in England that had underwritten the merchandise it contained to an amount far exceeding its worth. James Robertson ARNOLD was the only one of the four children born in America. At the time of the treason he was a child and had just reached West Point from Philadelphia with his mother. He entered the British Army in 1798 and rose to the rank of Colonel of Engineers. He was stationed at Bermuda from 1816 to 1818 and from last named year to 1823 was at Halifax, the commanding officer of engineers of N.S. and N.B. While thus in command, he was in Saint John and on going into a house built by his father in King St. (stillstanding, Bragg's Bldg.) he wept like a child Since the accession of Queens Victoria he has been an Aide de Camp. In 1841 he was transferred from Engineer Corps and appointed Major General and Knight of the Royal Hanoverian Guelphic Order. Edward ARNOLD, the next son was some years ago in a banking house in England. George ARNOLD in 1816 was an officer of the Dragoons. Of the fate of Sophia ARNOLD nothing is known. It may be added that Benedict Arnold's mother had six children of whom he and his sister alone lived to maturity. The sister adhered to her brother through out his eventful and guilty career. She died at Montague, Upper Canada in 1803.
