One of the few aspects of Fort Warren into which I did not have time to slither was Battery Lowell, named for Brigadier General Charles William Lowell, who was mortally wounded in the Shenandoah Valley in August of 1864 during, you guessed it, the US Civil War. This may have been the actual reason the US declared war on Spain in 1898: They needed more American dudes to die heroically (and recently) so the US Army could name stuff after them.

This battery mounted three 3" "Masking Parapet" guns from 1900 to 1920, when they were transferred to Watervliet Arsenal. These relatively small guns were intended to dissuade smaller enemy naval vessels from interfering with electrically-fired minefields, which would have been sprinkled delicately through strategic waterways.

This battery was built atop the ruins of Fort Warren's ravelin, which originally jutted menacingly out in front to the south of the fort, and which was cruelly bulldozed to make way for this Endicottian ugliness.
