He [Capt. Francis Dease] figured at the capture of Prairie du Chien. He was rather a young appearing man in 1814... . He may have commanded at Prairie du Chien under orders of Col. Dickson in April 1814 before the arrival of Americans... .
Capt. Francis Michael Dease, as I learn from his nephew, John Dease, of Pembina Co., Dakota, was born at Niagara, Aug. 10th, 1786. He seems to have taken part in the capture of Mackinaw from the Americans in 1812; probably served with Col. Robert Dickson on the Maumee in 1813; and shared in the capture of Prairie de Chien in 1814.
He was never married, and died on Red River, now Manitoba, Aug. 15th, 1865, at the age of seventy-nine years.
