Thayer's Note:

a This glosses over, somewhat inexplicably to my mind, the signal service to the Union for which Slemmer is remembered today: his refusal, despite very unfavorable circumstances, to surrender Ft. Pickens to the Confederacy. The fort, deep in Southern territory, held out for the duration of the war; strategically commanding the Gulf of Mexico. The details are much more interesting than one would expect; see "Civil War Operations in and around Pensacola" (FlaHQ 36:125‑165).
