The measures of General Gage had not been shrouded in all the secrecy he imagined. Dr. Joseph Warren, one of the committee of safety, had observed the preparatory disposition of the boats and troops, and surmised some sinister intention. He sent notice of these movements to John Hancock and Samuel Adams, both members of the provincial Congress, but at that time privately sojourning with a friend at Lexington. A design on the magazine at Concord was suspected, and the committee of safety ordered that the cannon collected there should be secreted and part of the stores removed. On the night of the 18th, Dr. Warren sent off two messengers by different routes to give the alarm that the king's troops were actually sallying forth. The messengers got out of Boston just before the order of General Gage went into effect, to prevent any one from leaving the town. About the same time a lantern was hung out of an upper window of the north church, in the direction of Charlestown. This was a preconcerted signal to the patriots of that place who instantly despatched swift messengers to rouse the country.
In the meantime, Colonel Smith set out on his nocturnal march from Lechmere Point by an unfrequented path across marshes, where at times the troops had to wade through water. He had proceeded but a few miles when alarm guns, booming through the night air, and the clang of village bells, showed that the news of his approach was travelling before him, and the people were rising. He now sent back to General Gage for a reinforcement, while Major Pitcairn was detached with six companies to press forward and secure the bridges at Concord.
Pitcairn advanced rapidly, capturing every one that he met or overtook. Within a mile and a half of Lexington, however, a horseman was too quick on the spur for him, and galloping to the village, gave the alarm that the redcoats were coming. Drums were beaten; guns fired. By the time that Pitcairn entered the village about seventy or eighty of the yeomanry, in military array, were mustered on the green near the church. The sound of drum, and the array of men in arms, indicated a hostile determination. Pitcairn halted his men within a short distance of the church, and ordered them to prime and load. They then advanced at double quick time. The major, riding forward ordered the rebels, as he termed them, to disperse. The order was disregarded. A scene of confusion ensued, with firing on both sides; which party commenced it has been a matter of dispute. The firing of the Americans was irregular and without much effect; that of the British was more fatal. Eight of the patriots were killed and ten wounded, and the whole put to flight. Colonel Smith soon arrived with the residue of the detachment, and they all marched on towards Concord, about six miles distant.
The alarm had reached that place in the dead hour of the preceding night. The church bell roused the inhabitants. They gathered together in anxious consultation. The militia and minute men seized their arms and repaired to the parade ground near the church. Exertions were now made to remove and conceal the military stores. A scout, who had been sent out for intelligence, brought word that the British had fired upon the people at Lexington and were advancing upon Concord. There was great excitement and indignation. Part of the militia marched down the Lexington road to meet them, but returned, reporting their force to be three times that of the Americans. The whole of the militia now retired to an eminence about a mile from the centre of the town, and formed themselves into two battalions.
About seven o'clock the British came in sight. They entered in two divisions by different roads. Concord is traversed by a river of the same name, having two bridges, the north and the south. The grenadiers and light infantry took post in the centre of the town, while strong parties of light troops were detached to secure the bridges, and destroy the military stores. Two hours were expended in the work of destruction without much success, so much of the stores having been removed, or concealed. During all this time the yeomanry from the neighboring towns were hurrying in with such weapons as were at hand, and joining the militia on the height, until the little cloud of war gathering there numbered about four hundred and fifty. About ten o'clock, a body of three hundred undertook to dislodge the British from the north bridge. As they approached, the latter fired upon them, killing two, and wounding a third. The patriots returned the fire with spirit and effect. The British retreated to the main body, the Americans pursuing them across the bridge.
By this time all the military stores which could be found had been destroyed; Colonel Smith, therefore, made preparations for a retreat. About noon he commenced his retrograde march for Boston. It was high time. His troops were jaded by the night march and the morning's toils and skirmishings.
The country was thoroughly alarmed. The yeomanry were hurrying from every quarter to the scene of action. As the British began their retreat, the Americans began the work of sore and galling retaliation. Along the open road the former were harassed incessantly by rustic marksmen, who took deliberate aim from behind trees or over stone fences. It was in vain they threw out flankers and endeavored to dislodge their assailants; each pause gave time for other pursuers to come within reach and open attacks from different quarters. For several miles they urged their way along woody defiles, or roads skirted with fences and stone walls, the retreat growing more and more disastrous. Before reaching Lexington, Colonel Smith received a severe wound in the leg, and the situation of the retreating troops was becoming extremely critical, when, about two o'clock, they were met by Lord Percy, with a brigade of one thousand men and two field-pieces. Opening his brigade to the right and left, he received the retreating troops into a hollow square; where, fainting and exhausted, they threw themselves on the ground to rest. His lordship showed no disposition to advance upon their assailants, but contented himself with keeping them at bay with his field-pieces, which opened a vigorous fire from an eminence.
Hitherto the Provincials, being hasty levies, without a leader, had acted from individual impulse, without much concert; but now General Heath was upon the ground. He was one of those authorized to take command when the minute men should be called out. Dr. Warren also arrived on horseback, having spurred from Boston on receiving news of the skirmishing. In the subsequent part of the day he was one of the most active and efficient men in the field. His presence, like that of General Heath, regulated the infuriated ardor of the militia and brought it into system.
Lord Percy, having allowed the troops a short interval for repose and refreshment, continued the retreat toward Boston. As soon as he got under march, the galling assault by the pursuing yeomanry was recommenced in flank and rear. The British soldiery, irritated in turn, acted as if in an enemy's country. Houses and shops were burnt down in Lexington; private dwellings along the road were plundered, and their inhabitants maltreated. Their march became more and more impeded by the number of their wounded. Lord Percy narrowly escaped death from a musket-ball, which struck off a button of his waistcoat. The provincials pressed upon him in rear, others were advancing from Roxbury, Dorchester, and Milton; Colonel Pickering, with the Essex militia, seven hundred strong, was at hand; there was danger of being intercepted in the retreat to Charlestown. The field-pieces were again brought into play to check the ardor of the pursuit; but they were no longer objects of terror. The pursuit terminated a little after sunset at Charlestown Common, where General Heath brought the minute men to a halt.
In this memorable affair the British loss was seventy-three killed, one hundred and seventy-four wounded and twenty-six missing. Among the slain were eighteen officers. The loss of the Americans was forty-nine killed, thirty-nine wounded, and five missing. This was the first blood shed in the revolutionary struggle. The cry went through the land. None felt the appeal more than the old soldiers of the French war. It roused John Stark, of New Hampshire—a trapper and hunter in his youth, a veteran in Indian warfare, a campaigner under Abercrombie and Amherst. Within ten minutes after receiving the alarm, he was spurring towards the sea-coast. Equally alert was
