Lieutenant-Colonel Stirling, from the moment of landing, was active in drilling the 42d in the methods of fighting practiced in the French and Indian war, in which he was well versed. The Highlanders made rapid progress in this discipline, being, in general, excellent marksmen.
It was about this time that the broadswords and pistols received at Glasgow were laid aside. The pistols were considered unnecessary, except in the field. The broadswords retarded the men when marching by getting entangled in the brushwood.
The reserve of Howe's army was landed first at Gravesend Bay, and being moved immediately forward to Flat Bush, the Highlanders and a corps of Hessians were detached to a little distance, where they encamped. The whole army encamped in front of the villages of Gravesend and Utrecht. A woody range of hills, which intersected the country from east to west, divided the opposing armies.
General Howe resolved to bring on a general action and make the attack in three divisions. The right wing under General Clinton seized, on the night of August 26th, a pass on the heights, about three miles from Bedford. The main body pushed into the level country which lay between the hills and the lines of General Israel Putnam. Whilst these movements were in process, Major-General Grant of Ballindalloch, with his brigade, supported by the Royal Highlanders from the reserve, was directed to march from the left along the coast to the Narrows, and make an attack in that quarter. At nine o'clock, on the morning of the 22nd, the right wing having reached Bedford, attacked the left of the American army, which, after a short resistance, quitted the woody grounds, and in confusion retired to their lines, pursued by the British troops, Colonel Stuart leading with his battalion of Highland grenadiers. When the firing at Bedford was heard at Flat Bush, the Hessians advanced, and, attacking the center of the American army, drove them through the woods, capturing three cannon. Previously, General Grant, with the left of the army, commenced the attack with a cannonade against the Americans under lord Stirling. The object of lord Stirling was to defend the pass and keep General Grant in check. He was in the British parliament when Grant made his speech against the Americans, and addressing his soldiers said, in allusion to the boasting Grant that he would "undertake to march from one end of the continent to the other, with five thousand men." "He may have his five thousand men with him now—we are not so many—but I think we are enough to prevent his advancing further on his march over the continent, than that mill-pond," pointing to the head of Gowanus bay. This little speech had a powerful effect, and in the action showed how keenly they felt the insult. General Grant had been instructed not to press an attack until informed by signal-guns from the right wing. These signals were not given until eleven o'clock, at which time lord Stirling was hemmed in. When the truth flashed upon him he hurled a few of his men against lord Cornwallis, in order to keep him at bay while a part of his army might escape. Lord Cornwallis yielded, and when on the point or retreating received large reinforcements which turned the fortunes of the day against the Americans. General Grant drove the remains of lord Stirling's army before him, which escaped across Gowanus creek, by wading and swimming.
The victorious troops, made hot and sanguinary by the fatigues and triumphs of the morning, rushed upon the American lines, eager to carry them by storm. But the day was not wholly lost. Behind the entrenchments were three thousand determined men who met the advancing British army by a severe cannonade and volleys of musketry. Preferring to win the remainder of the conquest with less bloodshed, General Howe called back his troops to a secure place in front of the American lines, beyond musket shot, and encamped for the night.
During the action Washington hastened over from New York to Brooklyn and galloped up to the works. He arrived there in time to witness the catastrophe. All night he was engaged in strengthening his position; and troops were ordered from New York. When the morning dawned heavy masses of vapor rolled in from the sea. At ten o'clock the British opened a cannonade on the American works, with frequent skirmishes throughout the day. Rain fell copiously all the afternoon and the main body of the British kept their tents, but when the storm abated towards evening, they commenced regular approaches within five hundred yards of the American works. That night Washington drew off his army of nine thousand men, with their munitions of war, transported them over a broad ferry to New York, using such consummate skill that the British were not aware of his intention until next morning, when the last boats of the rear guard were seen out of danger.
The American loss in the battle of Long Island did not exceed sixteen hundred and fifty, of whom eleven hundred were prisoners. General Howe stated his own loss to have been, in killed, wounded, and prisoners, three hundred and sixty-seven. The loss of the Highlanders was, Lieutenant Crammond and nine rank and file wounded, of the 42d; and three rank and filed killed, and two sergeants and nine rank and file wounded, of the 71st regiment.
In a letter to lord George Germaine, under date of September 4, 1776, lord Dunmore says:
"I was with the Highlanders and Hessians the whole day, and it is with the utmost pleasure I can assure your lordship that the ardour of both these corps on that day must have exceeded his Majesty's most sanguine wish."[163]
Active operations were not resumed until September 15th, when the British reserve, which the Royal Highlanders had rejoined after the action at Brooklyn, crossed the river in flat boats from Newtown creek, and landed at Kip's bay covered by a severe cannonade from the ships-of-war, whose guns played briskly upon the American batteries. Washington, hearing the firing, rode with speed towards the scene of action. To him a most alarming spectacle was presented. The militia had fled, and the Connecticut troops had caught the panic, and ran without firing a gun, when only fifty of the British had landed. Meeting the fugitives he used every endeavor to stop their flight. In vain their generals tried to rally them; but they continued to flee in the greatest confusion, leaving Washington alone within eighty yards of the foe. So incensed was he at their conduct that he cast his chapeau to the ground, snapped his pistols at several of the fugitives, and threatened others with his sword. So utterly unconscious was he of danger, that he probably would have fallen had not his attendants seized the bridle of his horse and hurried him away to a place of safety. Immediately he took measures to protect his imperilled army. He retreated to Harlem heights, and sent an order to General Putnam to evacuate the city instantly. This was fortunately accomplished, through the connivance of Mrs. Robert Murray. General Sir William Howe, instead of pushing forward and capturing the four thousand troops under General Putnam, immediately took up his quarters with his general officers at the mansion of Robert Murray, and sat down for refreshments and rest. Mrs. Murray knowing the value of time to the veteran Putnam, now in jeopardy, used all her art to detain her uninvited guests. With smiles and pleasant conversation, and a profusion of cakes and wine, she regaled them for almost two hours. General Putnam meanwhile receiving his orders, immediately obeyed, and a greater portion of his troops, concealed by the woods, escaped along the Bloomingdale road, and before being discovered had passed the encampment upon the Ineleberg. The rear-guard was attacked by the Highlanders and Hessians, just as a heavy rain began to fall; and the drenched army, after losing fifteen men killed, and three hundred made prisoners, reached Harlem heights.
