Schaumburg was sent with despatches to Donop, who, however, had been killed before the arrival of his young aide-de-camp. Learning for the first time of the righteousness of the American cause, he gallantly offered his services to the commander-in-chief of the American forces. He fought valiantly all through the war, and at its close accepted a commission in the standing army organized by the new government. At the Cotton Centennial held at New Orleans in 1884, his commissions signed by Washington were exhibited and were objects of much interest. He took part in many of the early Indian wars, and was appointed quartermaster-general in the war of 1812. [Illustration: Emilie Schaumburg (Mrs. Hughes-Hallett) From portrait by Waugh] His home was at New Orleans. His eldest daughter, at the time of General Lafayette's visit to that city, was one of the twelve young girls selected on account of their beauty from its most distinguished families to crown America's friend. She lived to an advanced age, surviving her eleven companions of that memorable occasion and retaining much of her beauty till the close of her life. The site of the city of Cincinnati was indirectly chosen by Colonel Schaumburg when he selected the spot where it later sprung up for the establishment of a fort, which he called, in honor of his first American friend, Fort Washington. He was an accomplished artillerist, and under his direction was cast the first cannon made in the United States. While stationed in Carlisle, Pennsylvania, upon military duty, he met the lady whom he afterwards married, and who had not long previously arrived in America, whither she had come with her parents to trace a recent acquisition of land. She was a lineal descendant of the principal Indian chief, Secaneh, of the Lenape tribe, who signed the treaty of 1683 with William Penn, selling him the large tract of land on which Philadelphia is built. The Princess Susahena, the daughter of Secaneh, had been married to Thomas Holme McFarlane, a nephew of Thomas Holme, who was the first Surveyor-General of Pennsylvania. Three years after their marriage they sailed for Dublin, but ocean voyages in those days were trials to the stoutest constitutions, and the poor princess died before reaching the other side. Her child, a daughter, lived, and it was the great-granddaughter of this child who became the wife of Colonel Schaumburg, so that Emilie Schaumburg is the seventh generation in lineal descent from the aboriginal princess, and attained her remarkable social queenship on the native heath of her royal ancestors.
