Fort C.F. Smith (2), Fort Strong (1), Fort Morton, and Fort Woodbury functioned as an outer perimeter of defenses called the Arlington Line that protected the Alexandria Canal and the Potomac River Aqueduct Bridge of the C&O Canal. The Potomac River Aqueduct Bridge connected the C & O Canal on the Washington side of the Potomac River with the Alexandria Canal on the Virginia side of the river. The bridge actually allowed the canal boats to cross the river and travel down the Virginia side to the Port of Alexandria.
