The Battles of Lexington and Concord was the first major military campaign of the American Revolutionary War, resulting in an American victory and outpouring of militia support for the anti-British cause.[9] The battles were fought on April 19, 1775, in Middlesex County, Province of Massachusetts Bay, within the towns of Lexington, Concord, Lincoln, Menotomy (present-day Arlington), and Cambridge. They marked the outbreak of armed conflict between the Kingdom of Great Britain and Patriot militias from America's thirteen colonies.
In late 1774, Colonial leaders adopted the Suffolk Resolves in resistance to the alterations made to the Massachusetts colonial government by the British parliament following the Boston Tea Party. The colonial assembly responded by forming a Patriot provisional government known as the Massachusetts Provincial Congress and calling for local militias to train for possible hostilities. The Colonial government effectively controlled the colony outside of British-controlled Boston. In response, the British government in February 1775 declared Massachusetts to be in a state of rebellion.
About 700 British Army regulars in Boston, under Lieutenant Colonel Francis Smith, were given secret orders to capture and destroy Colonial military supplies reportedly stored by the Massachusetts militia at Concord. Through effective intelligence gathering, Patriot leaders had received word weeks before the expedition that their supplies might be at risk and had moved most of them to other locations. On the night before the battle, warning of the British expedition had been rapidly sent from Boston to militias in the area by several riders, including Paul Revere and Samuel Prescott, with information about British plans. The initial mode of the Army's arrival by water was signaled from the Old North Church in Boston to Charlestown using lanterns to communicate "one if by land, two if by sea".
The first shots were fired just as the sun was rising at Lexington. Eight militiamen were killed, including Ensign Robert Munroe, their third in command.[10] The British suffered only one casualty. The militia was outnumbered and fell back, and the regulars proceeded on to Concord, where they broke apart into companies to search for the supplies. At the North Bridge in Concord, approximately 400 militiamen engaged 100 regulars from three companies of the King's troops at about 11:00 am, resulting in casualties on both sides. The outnumbered regulars fell back from the bridge and rejoined the main body of British forces in Concord.
The British forces began their return march to Boston after completing their search for military supplies, and more militiamen continued to arrive from the neighboring towns. Gunfire erupted again between the two sides and continued throughout the day as the regulars marched back towards Boston. Upon returning to Lexington, Lt. Col. Smith's expedition was rescued by reinforcements under Brigadier General Earl Percy. The combined force of about 1,700 men marched back to Boston under heavy fire in a tactical withdrawal and eventually reached the safety of Charlestown. The accumulated militias then blockaded the narrow land accesses to Charlestown and Boston, starting the siege of Boston.
Ralph Waldo Emerson describes the first shot fired by the Patriots at the North Bridge in his "Concord Hymn" as the "shot heard round the world".[11]
The British Army's infantry were nicknamed "redcoats" and sometimes "devils" by the colonists. They had occupied Boston since 1768 and had been augmented by naval forces and marines to enforce what the colonists called The Intolerable Acts of 1774, which had been passed by the British Parliament to punish the Province of Massachusetts Bay for the Boston Tea Party and other acts of protest.
General Thomas Gage was the military governor of Massachusetts and commander-in-chief of the roughly 3,000 British military forces garrisoned in Boston. He had no control over Massachusetts outside of Boston, however, where the implementation of the Acts had increased tensions between the Patriot Whig majority and the pro-British Tory minority. Gage's plan was to avoid conflict by removing military supplies from Whig militias using small, secret, and rapid strikes. This struggle for supplies led to one British success and several Patriot successes in a series of nearly bloodless conflicts known as the Powder Alarms. Gage considered himself to be a friend of liberty and attempted to separate his duties as governor of the colony and as general of an occupying force. Edmund Burke described Gage's conflicted relationship with Massachusetts by saying in Parliament, "An Englishman is the unfittest person on Earth to argue another Englishman into slavery."[12]
The colonists had been forming militias since the very beginnings of Colonial settlement for the purpose of defense against Indian attacks. These forces also saw action in the French and Indian War between 1754 and 1763 when they fought alongside British regulars. Under the laws of each New England colony, all towns were obligated to form militia companies composed of all males 16 years of age and older (there were exemptions for some categories) and to ensure that the members were properly armed. The Massachusetts militias were formally under the jurisdiction of the provincial government, but militia companies throughout New England elected their own officers.[13] Gage effectively dissolved the provincial government under the terms of the Massachusetts Government Act, and these existing connections were employed by the colonists under the Massachusetts Provincial Congress for the purpose of resistance to the military threat from Britain.[14]
A February 1775 address to King George III, by both houses of Parliament, declared that a state of rebellion existed:
We ... find that a part of your Majesty' s subjects, in the Province of the Massachusetts Bay, have proceeded so far to resist the authority of the supreme Legislature, that a rebellion at this time actually exists within the said Province; and we see, with the utmost concern, that they have been countenanced and encouraged by unlawful combinations and engagements entered into by your Majesty's subjects in several of the other Colonies, to the injury and oppression of many of their innocent fellow-subjects, resident within the Kingdom of Great Britain, and the rest of your Majesty' s Dominions ... We ... shall ... pay attention and regard to any real grievances ... laid before us; and whenever any of the Colonies shall make a proper application to us, we shall be ready to afford them every just and reasonable indulgence. At the same time we ... beseech your Majesty that you will ... enforce due obedience to the laws and authority of the supreme Legislature; and ... it is our fixed resolution, at the hazard of our lives and properties, to stand by your Majesty against all rebellious attempts in the maintenance of the just rights of your Majesty, and the two Houses of Parliament.[15]
On April 14, 1775, Gage received instructions from Secretary of State William Legge, Earl of Dartmouth, to disarm the rebels and to imprison the rebellion's leaders, but Dartmouth gave Gage considerable discretion in his commands.[16] Gage's decision to act promptly may have been influenced by the information he received on April 15, from a spy within the Provincial Congress, telling him that although the Congress was still divided on the need for armed resistance, delegates were being sent to the other New England colonies to see if they would cooperate in raising a New England army of 18,000 colonial soldiers.[17]
On the morning of April 18, Gage ordered a mounted patrol of about 20 men under the command of Major Mitchell of the 5th Regiment of Foot into the surrounding country to intercept messengers who might be out on horseback.[18] This patrol behaved differently from patrols sent out from Boston in the past, staying out after dark and asking travelers about the location of Samuel Adams and John Hancock. This had the unintended effect of alarming many residents and increasing their preparedness. The Lexington militia, in particular, began to muster early that evening, hours before receiving any word from Boston. A well-known story alleges that after nightfall one farmer, Josiah Nelson, mistook the British patrol for the colonists and asked them, "Have you heard anything about when the regulars are coming out?" upon which he was slashed on his scalp with a sword. However, the story of this incident was not published until over a century later, which suggests that it may be a family myth.[19]
Lieutenant Colonel Francis Smith received orders from Gage on the afternoon of April 18 with instructions that he was not to read them until his troops were underway. He was to proceed from Boston "with utmost expedition and secrecy to Concord, where you will seize and destroy ... all Military stores ... But you will take care that the soldiers do not plunder the inhabitants or hurt private property." Gage used his discretion and did not issue written orders for the arrest of rebel leaders, as he feared doing so might spark an uprising.[20]
On March 30, 1775, the Massachusetts Provincial Congress issued the following resolution:
Whenever the army under command of General Gage, or any part thereof to the number of five hundred, shall march out of the town of Boston, with artillery and baggage, it ought to be deemed a design to carry into execution by force the late acts of Parliament, the attempting of which, by the resolve of the late honourable Continental Congress, ought to be opposed; and therefore the military force of the Province ought to be assembled, and an army of observation immediately formed, to act solely on the defensive so long as it can be justified on the principles of reason and self-preservation.[22]
The rebellion's leaders—with the exception of Paul Revere and Joseph Warren—had all left Boston by April 8. They had received word of Dartmouth's secret instructions to General Gage from sources in London well before they reached Gage himself.[23] Adams and Hancock had fled Boston to the home of one of Hancock's relatives, Jonas Clarke, where they thought they would be safe from the immediate threat of arrest.[24]
The Massachusetts militias had indeed been gathering a stock of weapons, powder, and supplies at Concord and much further west in Worcester.[25] An expedition from Boston to Concord was widely anticipated. After a large contingent of regulars alarmed the countryside by an expedition from Boston to Watertown on March 30, The Pennsylvania Journal, a newspaper in Philadelphia, reported, "It was supposed they were going to Concord, where the Provincial Congress is now sitting. A quantity of provisions and warlike stores are lodged there. ... It is ... said they are intending to go out again soon."[26]
On April 18, Paul Revere began the "midnight ride" to Concord to warn the inhabitants that the British appeared to be planning an expedition. The ride was finished by Samuel Prescott. Upon hearing Prescott's news, the townspeople decided to remove the stores and distribute them among other towns nearby.[27]
The colonists were also aware that April 19 would be the date of the expedition, despite Gage's efforts to keep the details hidden from all the British rank and file and even from the officers who would command the mission. There is reasonable speculation that the confidential source of this intelligence was Margaret Gage, General Gage's New Jersey-born wife, who had sympathies with the Colonial cause and a friendly relationship with Warren.[28]
Between 9 and 10 pm on the night of April 18, 1775, Joseph Warren told Revere and William Dawes that the British troops were about to embark in boats from Boston bound for Cambridge and the road to Lexington and Concord. Warren's intelligence suggested that the most likely objectives of the regulars' movements later that night would be the capture of Adams and Hancock. They did not worry about the possibility of regulars marching to Concord, since the supplies at Concord were safe, but they did think their leaders in Lexington were unaware of the potential danger that night. Revere and Dawes were sent out to warn them and to alert colonial militias in nearby towns.[29]
