So far from this, the squadron was not equal, in either number or quality, to the work to be done about Boston; and it was not until October, 1775, that the Admiral was authorized to capture colonial merchant vessels, which therefore went and came unmolested, outside of Boston, carrying often provisions which found their way to Washington's army.
After evacuating Boston, General Howe retired to Halifax, there to await the coming of reinforcements, both military and naval, and of his brother, Vice-Admiral Lord Howe, appointed to command the North American Station.

General Howe was commander-in-chief of the forces throughout the territory extending from Nova Scotia to West Florida; from Halifax to Pensacola.

The first operation of the campaign was to be the reduction of New York.
The British government, however, had several objects in view, and permitted itself to be distracted from the single-minded prosecution of one great undertaking to other subsidiary operations, not always concentric.

Whether the control of the line of the Hudson and Lake Champlain ought to have been sought through operations beginning at both ends, is open to argument; the facts that the Americans were back in Crown Point in the beginning of July, 1776, and that Carleton's 13,000 men got no farther than St.John's that year, suggest that the greater part of the latter force would have been better employed in New York and New Jersey than about Champlain.

However that may be, the diversion to the Carolinas of a third body, respectable in point of numbers, is scarcely to be defended on military grounds.
