Guillaume-Mathieu Dumas (1753-1837) French general. Dumas was aide-de-camp to Rochambeau in the American Revolutionary War. He had a share in all the principal engagements that occurred during a period of nearly two years.

He again had to flee until Napoleon Bonaparte became First Consul in 1799, and returned to organize the army. He helped with administration of the army under Louis XVIII, but at first did not offer his expertise to Napoleon when he returned from Elba, although later he helped to organize the National Guard. 8 ¼” x 12 ½” document signed, “Cte.
