Thomas Dwyer
MSA SC 3520-17581


Thomas Dwyer enlisted as a sergeant in the Sixth Company of the First Maryland Regiment, led by Captain Peter Adams, on January 30, 1776. [1]

The Sixth Company was recruited primarily from the Eastern Shore, but traveled to Annapolis  in the spring of 1776 to complete six months of training.  They then moved north, making it to Philadelphia by mid-July 1776 and to New York by August 14.  They positioned themselves, along with the rest of the First Maryland Regiment, about one mile outside of New York, with orders to prepare for battle.

The Marylanders met the British at the Battle of Brooklyn (sometimes called the Battle of Long Island) on August 27, 1776, where the Continental Army, led by General George Washington, fought to defend New York. The  American troops were severely outnumbered and surrounded when they were ordered to retreat.  Half the regiment was able to escape the battle, however the other half, including most of the Sixth Company, was trapped by the swampy Gowanus Creek.  They turned back to face the British, holding their position long enough for the rest of the Marylanders to return to safety.  This heroic stand earned them the honorable name of the “Maryland 400.” [2]

The First Maryland Regiment suffered major losses. The Sixth Company alone lost 58 men, or 80 percent. By the end of the battle, Maryland losses totalled 256 men killed or captured.  Despite the heroic actions of the Maryland 400, the battle was a defeat for the Americans. [3]

Thomas Dwyer’s fate at the battle is unknown, however the Sixth Company had no sergeants present after the battle, so it is likely that he was killed or possibly captured.  A man named Thomas Dwyer enlisted in the Fourth Maryland Regiment in 1778, although there is no evidence linking this man with the Dwyer who fought at the Battle of Brooklyn.
