MSA SC 3520-17732
Patrick Costigin enlisted as a private in the Eighth Company of the First Maryland Regiment on January 23, 1776. The regiment was Maryland's first contingent of full-time, professional soldiers raised to be part of the Continental Army. The Eighth Company, commanded by Captain Samuel Smith, formed in Baltimore in early 1776, and it trained there that spring and summer. Two other companies from the regiment were located in Baltimore as well, while the rest were stationed in Annapolis. In July, the regiment was ordered to march north to New York, to protect the city from invasion by the British. The Eighth Company lost four men who deserted along the march, a problem which plagued the regiment that summer. 
On August 27, 1776, the Americans faced the British Army at the Battle of Brooklyn (sometimes called the Battle of Long Island), the first full-scale engagement of the war. The battle was a rout: the British were able to sneak around the American lines, and the outflanked Americans fled in disarray. As the Maryland troops fought their way towards the American fortifications, they were forced to stop at the swampy Gowanus Creek. Half the regiment, including the Eighth, was able to cross the creek and escape the battle. However, the rest were unable to do so before they were attacked by the British. Facing down a much larger, better-trained force, this group of soldiers, today called the "Maryland 400," mounted a series of daring charges. They held the British at bay for some time before being overrun, at the cost of many lives, losing 256 men killed or captured. Because the Eighth was able to escape the battle early, it lost only about six men. 
Costigin's fate at the battle is not known, and nothing else definite can be learned about his life.
