At this time, Dr. Warren and General Heath were active in the field, directing and encouraging the militia. General Heath was one of the generals who were authorized to take the command when the minute-men should be called out. On his way to the scene of action he ordered the militia of Cambridge to make a barricade of the planks of the bridge, take post there, and oppose the retreat of the British in that direction from Boston. At Lexington, when the minute-men were somewhat checked and scattered by Percy's field-pieces, he labored to form them into military order. Dr. Warren, about ten o'clock, rode on horseback through Charlestown. He had received by express intelligence of the events of the morning, and told the citizens of Charlestown that the news of the firing was true. Among others he met Dr. Welsh, who said, "Well, they are gone out." "Yes," replied the doctor, "and we'll be up with them before night."
Lord Percy had now under his command about eighteen hundred troops of undoubted bravery and of veteran discipline. He evinced no disposition, however, to turn upon his assailants and make good the insulting boasts of his associates. After a short interval of rest and refreshment the British recommenced their retreat. Then the Provincials renewed their attack. In West Cambridge the skirmishing again became sharp and bloody and the troops increased their atrocities. Jason Russell, an invalid and a noncombatant, was barbarously butchered in his own house. In this town a mother was killed while nursing her child. Others were driven from their dwellings, and their dwellings were pillaged. Here the Danvers company, which marched in advance of the Essex regiment, met the enemy. Some took post in a walled enclosure, and made a breastwork of bundles of shingles; others planted themselves behind trees on the side of the hill west of the meeting-house. The British came along in solid column on their right, while a large flank guard came up on their left. The Danvers men were surrounded, and many were killed and wounded. Here Samuel Whittemore was shot and bayoneted, and left for dead. Here Dr. Eliphalet Downer, in single combat with a soldier, killed him with a bayonet. Here a musket-ball struck a pin out of the hair of Dr. Warren's earlock.
The wanton destruction of life and property that marked the course of the invaders added revenge to the natural bravery of the minute-men. "Indignation and outraged humanity struggled on the one hand; veteran discipline and desperation on the other." The British had many struck in West Cambridge, and left an officer wounded in the house still standing at the rail-road depot. The British troops took the road that winds round Prospect hill. When they entered this part of Charlestown their situation was critical. The large numbers of the wounded proved a distressing obstruction to their progress, while they had but few rounds of ammunition left. Their field-pieces had lost their terror. The main body of the Provincials hung closely on their rear; a strong force was advancing upon them from Roxbury, Dorchester, and Milton; while Colonel Pickering, with the Essex militia, seven hundred strong, threatened to cut off their retreat to Charlestown.
Near Prospect hill the fire again became sharp and the British again had recourse to their field-pieces. James Miller, of Charlestown, was killed here. Along its base, Lord Percy, it is stated, received the hottest fire he had during his retreat. General Gage, about sunset, might have beheld his harassed troops, almost on the run, coming down the old Cambridge road to Charlestown Neck, anxious to get under the protection of the guns of the ships-of-war. The minute-men closely followed, but, when they reached the Charlestown Common, General Heath ordered them to stop the pursuit.
Charlestown, throughout the day, presented a scene of intense excitement and great confusion. It was known early in the morning that the regulars were out. Rumors soon arrived of the events that had occurred at Lexington. The schools were dismissed, and citizens gathered in groups in the streets. After Dr. Warren rode through the town, and gave the certain intelligence of the slaughter at Lexington, a large number went out to the field, and the greater part who remained were women and children. Hon. James Russell received, in the afternoon, a note from General Gage to the effect that he had been informed that citizens had gone out armed to oppose his majesty's troops, and that if a single man more went out armed the most disagreeable consequences might be expected. It was next reported, and correctly, that Cambridge bridge had been taken up, and that hence the regulars would be obliged to return to Boston through the town. Many then prepared to leave, and every vehicle was employed to carry away their most valuable effects. Others, however, still believing the troops would return the way they went out, determined to remain, and in either event to abide the worst. Just before sunset the noise of distant firing was heard, and soon the British troops were seen in the Cambridge road.
The inhabitants then rushed toward the neck. Some crossed Mystic River, at Penny Ferry. Some ran along the marsh, toward Medford. The troops, however, soon approached the town, firing as they came along. A lad, Edward Barber, was killed on the neck. The inhabitants then turned back into the town panic-stricken.
Word ran through the crowd that "the British were massacring the women and children!" Some remained in the streets, speechless with terror; some ran to the clay-pits, back of Breed's Hill, where they passed the night. The troops, however, offered no injury to the inhabitants. Their officers directed the women and children, half-distracted with fright, to go into their houses, and they would be safe, but requested them to hand out drink to the troops. The main body occupied Bunker Hill, and formed a line opposite the neck. Additional troops also were sent over from Boston. The officers flocked to the tavern in the square, where the cry was for drink. Guards were stationed in various parts of the town. One was placed at the neck, with orders to permit no one to go out. Everything, during the night, was quiet. Some of the wounded were carried over immediately, in the boats of the Somerset, to Boston. General Pigot had the command in Charlestown the next day, when the troops all returned to their quarters.
The Americans lost forty-nine killed, thirty-nine wounded, and five missing. A committee of the Provincial Congress estimated the value of the property destroyed by the ravages of the troops to be: In Lexington, £1761 15s. 5d.; in Concord, £274 16s. 7d.; in Cambridge, £1202 8s. 7d. Many petitions of persons who engaged the enemy on this day are on file. They lost guns or horses or suffered other damage. The General Court indemnified such losses.
The British lost seventy-three killed, one hundred seventy-four wounded, and twenty-six missing—the most of whom were taken prisoners. Of these, eighteen were officers, ten sergeants, two drummers, and two hundred forty were rank and file. Lieutenant Hall, wounded at the North bridge, was taken prisoner on the retreat, and died the next day. His remains were delivered to General Gage. Lieutenant Gould was wounded at the bridge, and taken prisoner, and was exchanged, May 28th, for Josiah Breed, of Lynn. He had a fortune of one thousand nine hundred pounds a year, and is said to have offered two thousand pounds for his ransom. The prisoners were treated with great humanity, and General Gage was notified that his own surgeons, if he desired it, might dress the wounded.
