Yesterday the Lords Sandwich, Germaine, Howe, and Admiral [John] Montagu, had a very long conference with his Majesty, and finally settled the plan of operations.in America. Admiral Montagu set out immediately for Portsmouth, and is,to sail with his fleet the first fair wind. Lord Howe will follow him as soon as the Eagle is ready to receive him. There is reason to hope that the appeararice of two such experienced and active commanders will soon put an end to the naval equipment of those unhappy deluded people the Americans, without the effusion of much blood.
