About Thomas Lancaster Lansdale

Major Thomas Lancaster Lansdale (1748-1803) was an original member of the Maryland chapter of the Society of the Cincinnati.

Military service

He served in the Continental Army from 1776 through 1783 as an officer in the 3rd Maryland Continental Infantry.

On January 25, 1783, Lansdale was berated in writing by George Washington for the shabby appearance of the troops under his command while encamped on the banks of the Hudson River. Lansdale redeemed himself two weeks later with Washington who then wrote:

"“It gave me very sensible pleasure to observe at the Review yesterday the very great alteration for the better in the appearance of the Maryland Detachment ... I anticipate the day when this Detachment will rival if not surpass in excellence the oldest & best Troops in the American Service.”


Outside of military service, he was a merchant with the firm of Lansdale and Claggett in the port town of Queen Anne[1] and owned a sizeable tobacco plantation in Prince George's County. He made his home at Hazelwood, overlooking Queen Anne.


His father was Isaac Lansdale who died in 1777. His wife was Cornelia Van Horn Lansdale. His grave in Collington, Maryland (now Bowie) is marked by a municipal park and a boulevard named in his honor.
