As the number of Union wounded and ill mounted, Alexandria's public building, churches, and even private homes were pressed into service as military hospitals. At least twenty of Alexandria's largest buildings were transformed into hospitals during the war. In January 1861, the U.S. Government took possession of Alexandria's Methodist Episcopal South church on Washington Street for use as a hospital. Like most other Alexandria churches, the Southern Methodist congregation was considered to be "secesh," so Union authorities had no qualms about seizing it.
