Secretary of the Navy John D. Long to Rear Admiral William T. Sampson, Commander, North Atlantic Fleet
Washington, May 3, 1898.
Sampson, Key West, Fla.:
No large army movement can take place for a fortnight, and no small one will until after we know the whereabouts of the four Spanish armored cruisers and destroyers. If their objective is Porto Rico they should arrive about May 8, and immediate action against them and San Juan is then authorized. In such case the Flying Squadron would reinforce you.
