Hazen and part of the regiment participated in a raid on January 22 led by Lieutenant Colonel William Hull. Hull raided a position held by a Loyalist corps under Lieutenant Colonel Oliver De Lancey Sr. that was at Morrisania (in the present-day Bronx). The Americans burned the enemy's barracks, captured 52 prisoners, and took large supplies of ammunition and forage. Hazen's men were assigned to cover their retreat. About 1,000 British troops pursued Hull's men beyond a point where Hazen and his men were concealed. A skirmish took place, with British losing about 35 men.
