April 19, 1775, is memorable in American history as the day on which occurred the first bloodshed of the Revolution. The two combats of the day—that at Lexington and that at Concord—really constituted one action, which ended in a long running fight. As a single action, it is usually called the Battle of Lexington. The engagement at Concord, separately considered, is called the Battle of Concord, or the Concord Fight.
At both places, on that fateful day, "the embattled farmers" faced the troops of their own sovereign, to resist what was felt to be an unwarranted and menacing invasion of American liberties. While the soldiers of King George were doing their own loyal duty, the New England yeomen who "fired the shot heard round the world" obeyed a conviction still more compelling. Hence came the first physical struggle in what was already an "irrepressible conflict" of principle between Englishmen and their kinsmen on the American continent.
The Revolutionary War was begun on the part of the Americans for the redress of grievances for which they had exhausted all peaceable endeavors to secure a remedy. It was afterward successfully waged for independence. Repressive measures of Great Britain in the colonies began with the issuance by colonial courts of "writs of assistance." These writs authorized officers to summon assistance in searching certain premises under certain laws. In the first attempt to enforce such a writ—in Massachusetts, 1761—the policy was defeated through popular opposition, brilliantly led by James Otis, who by a single speech produced such an effect that John Adams said of the occasion: "Then and there was the first scene of the first act of opposition to the arbitrary claims of Great Britain. Then and there the child Independence was born."
Later grievances were those of the Stamp Act (1765), taxes on paints, glass, etc. (1767), and the Boston Port Bill (1774), ordering the closing of the port on account of the rebellious acts of the citizens, especially in the "tea-party" of December 16, 1773, when they threw into the waters of the harbor from English ships tea valued at eighteen thousand pounds. As early as 1770 had occurred the "Boston Massacre," a collision between citizens and British soldiers, which added to earlier discontents and increased the sensitiveness to later irritations.
The first Continental Congress, in 1774, though strongly pacific, favored resistance to aggressions of the Crown. During this year and the next two Provincial Congresses met in Massachusetts, the collection of military stores was authorized, a committee of safety was created, and the "minute-men" were organized.
General Gage, the British commander in Boston, denounced these proceedings as treasonable. Parliament vainly sought to adjust the difficulties and enforce its authority. Conciliatory efforts on both sides failing, it soon became evident that a conflict of arms was at hand. By April 4, 1775, it was known in Boston that reënforcements were on their way to General Gage. Soon after their arrival he was ready for the movement with which the narrative of Frothingham, a high authority on these events, begins.
General Gage had, in the middle of April, 1775, about four thousand men in Boston. He resolved, by a secret expedition, to destroy the magazines collected at Concord. This measure was neither advised by his council nor by his officers. It was said that he was worried into it by the importunities of the Tories; but it was undoubtedly caused by the energetic measures of the Whigs. His own subsequent justification was that when he saw an assembly of men, unknown to the Constitution, wresting from him the public moneys and collecting warlike stores, it was alike his duty and the dictate of humanity to prevent the calamity of civil war by destroying these magazines. His previous belief was that should the Government show a respectable force in the field, seize the most obnoxious patriot leaders, and proclaim a pardon for others, it would come off victorious.
On April 15th the grenadiers and light infantry, on the pretence of learning a new military exercise, were relieved from duty; and at night the boats of the transport ships which had been hauled up to be repaired were launched and moored under the sterns of the men-of-war. These movements looked suspicious to the vigilant patriots, and Dr. Joseph Warren sent intelligence of them to Hancock and Adams, who were in Lexington. It was this timely notice that induced the committee of safety to take additional measures for the security of the stores in Concord, and to order (on the 17th) cannon to be secreted, and a part of the stores to be removed to Sudbury and Groton.
On Tuesday, April 18th, General Gage directed several officers to station themselves on the roads leading out of Boston, and prevent any intelligence of his intended expedition that night from reaching the country. A party of them, on that day, dined at Cambridge. The committees of safety and supplies, which usually held their sessions together, also met that day, at Wetherby's Tavern, in Menotomy, now West Cambridge. Elbridge Gerry and Colonels Orne and Lee, of the members, remained to pass the night. Richard Devens and Abraham Watson rode in a chaise toward Charlestown, but, soon meeting a number of British officers on horseback, they returned to inform their friends at the tavern, waited there until the officers rode by, and then rode to Charlestown. Gerry immediately sent an express to Hancock and Adams, that "eight or nine officers were out, suspected of some evil design," which caused precautionary measures to be adopted at Lexington.
Richard Devens, an efficient member of the committee of safety, soon received intelligence that the British troops were in motion in Boston, and were certainly preparing to go into the country. Shortly after, the signal agreed upon in this event was given, namely, a lantern hung out from the North Church steeple in Boston, when Devens immediately despatched an express with this intelligence to Menotomy and Lexington. All this while General Gage supposed his movements were a profound secret, and as such in the evening communicated them in confidence to Lord Percy. But as this nobleman was crossing the Common on his way to his quarters he joined a group of men engaged in conversation, when one said, "The British troops have marched, but will miss their aim!"
