Private Cromwell served in several
companies of the
2nd New Jersey Regiment between 1777 and 1783, seeing action at the battles of
Trenton (1776),
Princeton (1777),
Short Hills (1777),
Brandywine (1777),
Monmouth (1778), and at the final
siege of Yorktown (1781). After Yorktown, Cromwell left the army. Commander-in-Chief
George Washington personally signed Cromwell's discharge papers and also awarded him with the Badge of Merit. Some years after retirement, Cromwell applied for a veteran's pension. Although he was unable to read or write, local lawyers, judges, and politicians came to his aid, and he was granted a pension of $96 a year. He purchased a 100-acre farm outside Burlington, fathered 15 children, then spent his later years at his home at 114 East Union Street in Burlington. ==Death==
