Footnote 1: Sims’ Chief of Staff, Capt. Nathan C. Twining.

Footnote 2: Capt. Bernard de Blanpré, French Naval Attaché in Washington, D.C.

Footnote 3: On 5 October 1917, NAHMA, an armed yacht, was searching for a reported German submarine in the vicinity of Gibraltar when it sighted two submarines trailing a merchant ship. Believing that these submarines were attacking the ship, NAHMA opened fire, only to discover afterwards that the submarines belonged to the Italian Navy. Two Italian sailors on one of the submarines were fatally wounded, and the other Italian submarine narrowly escaped any damage, as the shell that hit it failed to detonate. Despite the fact that the French Naval Ministry did accede to the request Sims made herein, his fears were realized in May 1918, when a French submarine, ignoring warnings to avoid the area, was attacked by a Gibraltar-based American ships escorting a convoy through the Mediterranean; Still, Crisis at Sea, 396.
