The opening conflict between Great Britain and her North American Colonies teaches clearly the necessity, too rarely recognised in practice, that when a State has decided to use force, the force provided should be adequate from the first. This applies with equal weight to national policies when it is the intention of the nation to maintain them at all costs. The Monroe Doctrine for instance is such a policy; but unless constant adequate preparation is maintained also, the policy itself is but a vain form of words. It is in preparation beforehand, chiefly if not uniformly, that the United States has failed. It is better to be much too strong than a little too weak. Seeing the evident temper of the Massachusetts Colonists, force would be needed to execute the Boston Port Bill and its companion measures of 1774; for the Port Bill especially, naval force. The supplies for 1775 granted only 18,000 seamen—2000 less than for the previous year. For 1776, 28,000 seamen were voted, and the total appropriations rose from £5,556,000 to £10,154,000; but it was then too late. Boston was evacuated by the British army, 8000 strong on the 17th of March, 1776; but already, for more than half a year, the spreading spirit of revolt in the thirteen Colonies had been encouraged by the sight of the British army cooped up in the town, suffering from want of necessaries, while the colonial army blockading it was able to maintain its position, because ships laden with stores for the one were captured, and the cargoes diverted to the use of the other. To secure free and ample communications for one's self, and to interrupt those of the opponent, are among the first requirements of war. To carry out the measures of the British government a naval force was needed, which not only should protect the approach of its own transports to Boston Bay, but should prevent access to all coast ports whence supplies could be carried to the blockading army. 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. The government was induced to it by the expectation of local support from royalists. That there were many of these in both Carolinas is certain; but while military operations must take account of political conditions, the latter should not be allowed to overbalance elementary principles of the military art. It is said that General Howe disapproved of this ex-centric movement.

The force destined for the Southern coasts assembled at Cork towards the end of 1775, and sailed thence in January, 1776. The troops were commanded by Lord Cornwallis, the squadron by Nelson's early patron, Commodore Sir Peter Parker, whose broad pennant was hoisted on board the Bristol, 50. After a boisterous passage, the expedition arrived in May off Cape Fear in North Carolina, where it was joined by two thousand men under Sir Henry Clinton, Cornwallis's senior, whom Howe by the government's orders had detached to the southward in January. Upon Clinton's appearance, the royalists in North Carolina had risen, headed by the husband of Flora Macdonald, whose name thirty years before had been associated romantically with the escape of the young Pretender from Scotland. She had afterwards emigrated to America. The rising, however, had been put down, and Clinton had not thought it expedient to try a serious invasion, in face of the large force assembled to resist him. Upon Parker's coming, it was decided to make an attempt upon Charleston, South Carolina. The fleet therefore sailed from Cape Fear on the 1st of June, and on the 4th anchored off Charleston Bar.

Charleston Harbour opens between two of the sea-islands which fringe the coasts of South Carolina and Georgia. On the north is Sullivan's Island, on the south James Island. The bar of the main entrance was not abreast the mouth of the port, but some distance south of it. Inside the bar, the channel turned to the northward, and thence led near Sullivan's Island, the southern end of which was therefore chosen as the site of the rude fort hastily thrown up to meet this attack, and afterwards called Fort Moultrie, from the name of the commander. From these conditions, a southerly wind was needed to bring ships into action. After sounding and buoying the bar, the transports and frigates crossed on the 7th and anchored inside; but as it was necessary to remove some of the Bristol's guns, she could not follow until the 10th. On the 9th Clinton had landed in person with five hundred men, and by the 15th all the troops had disembarked upon Long Island, next north of Sullivan's. It was understood that the inlet between the two was fordable, allowing the troops to coöperate with the naval attack, by diversion or otherwise; but this proved to be a mistake. The passage was seven feet deep at low water, and there were no means for crossing; consequently a small American detachment in the scrub wood of the island sufficed to check any movement in that quarter. The fighting therefore was confined to the cannonading of the fort by the ships.

Circumstances not fully explained caused the attack to be fixed for the 23d; an inopportune delay, during which Americans were strengthening their still very imperfect defences. On the 23d the wind was unfavourable. On the 25th the Experiment, 50, arrived, crossed the bar, and, after taking in her guns again, was ready to join in the assault. On the 27th, at 10 A.m., the ships got under way with a south-east breeze, but this shifted soon afterwards to north-west, and they had to anchor again, about a mile nearer to Sullivan's Island. On the following day the wind served, and the attack was made.

In plan, Fort Moultrie was square, with a bastion at each angle. In construction, the sides were palmetto logs, dovetailed and bolted together, laid in parallel rows, sixteen feet apart; the interspace being filled with sand. At the time of the engagement, the south and west fronts were finished; the other fronts were only seven feet high, but surmounted by thick planks, to be tenable against escalade. Thirty-one guns were in place, 18 and 9-pounders, of which twenty-one were on the south face, commanding the channel. Within was a traverse running east and west, protecting the gunners from shots from the rear; but there was no such cover against enfilading fire, in case an enemy's ship passed the fort and anchored above it. "The general opinion before the action," Moultrie says, "and especially among sailors, was that two frigates would be sufficient to knock the town about our ears, notwithstanding our batteries." Parker may have shared this impression, and it may account for his leisureliness. When the action began, the garrison had but twenty-eight rounds for each of twenty-six cannon, but this deficiency was unknown to the British.
