The officer who went in command of the companies of Artillery ordered for service in the South was Major Innes, an officer who commenced his career as a matross, and ended it as Commandant of the Invalid Battalion in 1783.

Colonel James commanded the detachments on board the bombs, and was much praised for the accuracy of his fire at the unsuccessful attack on Fort Sullivan, near Charlestown, South Carolina, in June, 1776. He also commenced his career as a matross—in the year 1738—and died as a Colonel Commandant, in 1782.

Several cadets were sent out to fill vacancies as they might occur, instead of promoting non-commissioned officers. While doing duty, awaiting these vacancies, they received pay as Second Lieutenants.

Among the guns sent out for the campaign of 1776 were some light 24-pounders with travelling carriages, some 12-pounders, an immense number of light 3-pounders with Congreve's carriages, and some mortars for pound-shot. It was intended by the English Government, that this campaign should be decisive; and the fleet, army, and Artillery were very powerful. Lord Howe commanded the fleet, and his brother commanded the army; and they had full powers to treat with the rebels with a view to a cessation of hostilities, provided they should submit. The army left Halifax in June, 1776, and landed on Staten Island on the 3rd July; the whole of the Artillery being disembarked by the 7th of the month. Here they were joined by Sir Henry Clinton's forces from the South, and by Lord Howe and his fleet from England. A large force of Hessians and Waldeckers also joined them; and on the 22nd August, the army crossed to Long Island without molestation. The Americans were encamped at the north end of the island, where the city of Brooklyn now stands—protected behind by batteries, on the left by East River, and on the right by a marsh. A range of wooded hills separated the two armies, the passes being in the possession of the rebels. On the 27th, the Battle of Long Island—or Battle of Brooklyn, as it is indifferently called—was fought. The share taken by the Artillery in this victory, was—owing to the nature of the ground, and the hurried retreat of the Americans within their lines—but small. There were forty guns present: six with Lord Cornwallis's brigade; fourteen with General Clinton in the van; ten with the main body under Lord Percy; and four 12-pounders with the 49th Regiment in rear. The loss consisted of but three killed—Lieutenant Lovell, a sergeant, and a bombardier. So difficult were the 3-pounder guns on truck carriages found either to be moved or carried, that Brigadier Cleaveland sent them on board ship, and replaced them with those mounted on Congreve's carriages. From the loyalist farmers on Long Island, an additional hundred horses were bought for the Artillery, and eighty two-horse waggons, with drivers, hired for the conveyance of ammunition and stores.

One of the greatest blots on Sir William Howe's generalship was his omission to follow up the victory he won on Long Island. Had he done so, his troops being flushed with victory, and the enemy being disheartened and disunited, it is possible that he might have put an end to the war. By means of his apathy or neglect, Washington's troops were able to cross over to New York unmolested. Before attacking New York, the English commander considered it desirable to destroy a very strong redoubt, at a place called Hell Gate, mounted with a considerable number of guns to prevent communication, should it be attempted by the British troops, from the East River into the Sound. Four batteries were accordingly erected by the Royal Artillery on the opposite shore, mounting three 24-pounders, three heavy and three medium 12-pounders, and ten small mortars. As it eventually happened, the landing of the British in New York was made at a spot where the Hell Gate redoubt would have been useless; but it was satisfactory to find, on entering it afterwards, the enemy's guns dismounted, and the works so shattered, that the troops might have marched in with little or no impediment. In the Brigadier's report on this occasion, he said, "The distance was near 700 yards, and though the enemy threw a number of shells from six mortars, we had only on this occasion two men killed, and one lost an arm. It is with infinite satisfaction that I can say, that whenever the Artillery is employed, they have not only the approbation of the Commander-in-Chief, but the whole army, for their behaviour."

The British landed on Manhattan Island, under the fire of the ships; and in the precipitate retreat to the heights of Haarlem, the Americans lost their artillery, and many stores, and Washington nearly despaired of ever succeeding with such troops as he had under his command. But it was not enough to obtain possession of New York, unless the rebel forces could be dislodged from the powerful position they occupied in the north of the island; and to do this, an engagement on no small scale was necessary, and was commenced on the 27th October, 1776. Its opening was called the Battle of the White Plains; and viewing it from the Artillery point of view, it may be described as follows (bearing in mind that it was only the opening scene of a series of engagements, all intimately connected, and resulting in the scattering of Washington's forces, their expulsion from New York Island, and almost from the Jerseys; the capture of Forts Washington and Lee, and the complete command of the Lower Hudson):—The attack of the 27th October on the White Plains commenced with a cannonade on the enemy's left wing, with nearly thirty guns, manned by the Royal Artillery. On the 28th, the attack of the Hessian troops was covered by six light 12-pounders; and General Knyphausen publicly thanked the officers and men who were attached to them. In the attack on Fort Washington in the beginning of November, the Royal Artillery had thirty-four guns in action to cover the troops. The Guards and Light Infantry who were engaged in the attack crossed the East River in boats under the protection of batteries erected for the purpose. The hill they had to ascend from their landing was exceedingly rugged and steep, and the boats in which they crossed were exposed to the fire of two of the American batteries. To silence these, the batteries above-mentioned were built, and armed with four medium 12-pounders, fourteen light 6-pounders, four howitzers, and two mortars. With this armament, the rebel fire was soon silenced, with the exception of one 3-pounder, which was sheltered by a rock, and which did considerable damage. A battalion of the rebel forces which was marching for the defence of the hill was also entirely broken and dispersed by the well-directed fire of the Royal Artillery, under which the Guards and Light Infantry landed, and gained the hill without losing a man. The 42nd Regiment, which landed at another place, was covered by four 6-pounders; and six guns advanced with Lord Percy, from the lines at New York, and gained the heights of Haarlem, every gun being engaged. In this attack, the Artillery is described as having been powerful and well-served; officers and men received public acknowledgment in General Orders, and from the Master-General; and in answering the latter's commendations, Brigadier Cleaveland felt justified in saying: "The officers and men under my command have shown an unwearied application to the service, and deserve everything I can say in their favour.... The good opinion your Lordship is pleased to form of the conduct and superior abilities of the British Artillery when engaged, does them the highest honour, and I have the pleasure to inform your Lordship, that both officers and men have been emulous during the course of the campaign in deserving it."

The attack on the fort was too powerful to be resisted; so it capitulated. Lord Cornwallis, with a large body of men immediately crossed the North River, to attack Fort Lee, but it was abandoned by its garrison on the 18th November, and all the guns and stores fell into the hands of the English.

The English now overran the Jerseys, and the following guns were present with the Royal Artillery during the raid: four light 12-pounders, fourteen 6-pounders, eight 3-pounders, and two 5½-inch howitzers. This was a very critical period for the American cause, almost as much so as after the Battle of Long Island. "During these operations, the New York Convention was greatly alarmed lest the numerous forces (i.e. loyalists) of the State should rise in arms, and openly join the British forces. Often obliged by the movements of the armies to change its locality, that body sat successively at Haarlem, King's Bridge, Philip's Manor, Croton River, and Fishkill; some of the time, to guard against surprise, with arms in their hands. A committee was appointed for inquiring into, detecting, and defeating conspiracies. That committee had funds at its disposal, a special armed force, and unlimited powers. Many Tories were seized by its orders and sent into Connecticut for safe-keeping, their personal property being forfeited to the use of the State.... Some of the New York Militia (in Washington's camp) refused to do duty. They were offered—they said—peace, liberty, and safety, and what more could they ask."[[35]] While not underrating the energy of a people who could attain their end in spite of such difficulties, it is healthy reading occasionally, in the midst of flabby orations as to the uprising of a united people, to examine passages like that just quoted. A large substratum of loyalty existed yet, which had to be kept down by a sort of reign of terror; and although, as we shall see, the loyal diminished greatly in numbers as the war went on, the fact remains that the rebellion was not a national conception, but a party manœuvre, which secured by dexterous management the assistance of many pure and noble men, and ultimately—assisted by war—received the co-operation of the mass of the people. The war bound the people together by an instinct of self-defence, apart from the reasons which had brought it about; and once committed to a cause, men are as ingenious in inventing, often unconsciously, arguments in its favour, as they are enthusiastic in defending their opinions.

The gloom of the American cause in the end of 1776 was brightened by a surprise of some German troops at Trenton, by Washington, who took the whole prisoners, to the number of about 1000. This success did much to re-animate the rebels, and gave a new life to their prosecution of the war.

The year 1777 was destined to be the most eventful year of the whole campaign. The British had formed a plan, whose aim was as good as its execution was foolish. Prior, however, to its commencement, Washington made an attack on two regiments, the 17th and 55th, near Princeton, which is described in Brigadier Cleaveland's despatch to the Board of Ordnance in the following words:—"The most particular action that has happened since Washington's recrossing the Delaware, was an attack made by him with 4000 men, upon the Battalion of the 17th Regiment at Princeton, in which action the 17th has gained great honour, and their Lieutenant-Colonel, Mawhood, great reputation. The heavy fire of the enemy at the first of the attack obliged the Regiment to retire, under cover of four 6-pounders advantageously posted. Here the Regiment formed, and made a general charge upon the enemy, whom they forced wherever they advanced, leaving a piece of cannon behind them. Colonel Mawhood observing the enemy increasing greatly in their numbers, thought proper to march from Princeton, where we were obliged to leave two 6-pounders, all the horses belonging to the guns being shot, and the axletree of the other carriage broke by firing." At this affair, Lieutenant Desaguliers, and nine men of the Royal Artillery were killed. These active movements of Washington had the effect of making both General Howe and Lord Cornwallis withdraw their forces from Trenton and Princeton, and spend the rest of the winter near New York,—on Long Island, and in the neighbouring parts of New Jersey.
