Lexington Alarm

The Lexington Alarm announced, throughout the American Colonies, that the Revolutionary War began with the Battle of Lexington and the Siege of Boston on April 19, 1775. The goal was to rally patriots at a grass roots level to fight against the British Redcoats and support the minutemen of the Massachusetts militia.

Committees of correspondence
As the British Crown and Parliament policies created an increasingly greater divide with American colonists, the Sons of Liberty organization was founded. Samuel Adams led the creation of the Committees of correspondence, including the Committee of safety, to uphold the rights of colonists and communicate and respond to noteworthy events. Adams brought the issue before a town meeting in Boston on November 2, 1772. Soon the organization spread to other towns in Massachusetts and like-minded organizations were established by July 1773, in other colonies. A committee for intercolonial correspondence was established by Virginia's House of Burgesses. By 1774, there were committees established in every colony.

The network that was created allowed for planning and execution of activities when the colonial assemblies and the Continental Congress were not in session. Although the committees were not started as revolutionary endeavors, according E. D. Collins' Committees of Correspondence, "Its importance as a piece of revolutionary machinery can hardly be overestimated."

Towns developed the methods that they would use to manage and respond to dispatches, with Boston central to the overall network's operations. There were up to 8,000 delegates, or members, to the committee across the colonies, which became a mechanism for patriots to communicate with other patriots. Loyalists did not have a similar means to communicate throughout the colonies, which impacted the result of the war.

A false alarm was generated when the British removed 250 half-barrels of gun powder from a powder house in Charlestown, Massachusetts on September 1, 1774. Thirteen boats carried 260 British soldiers to carry off with the gun powder. A man warned that British soldiers were headed for Cambridge, initiating the Powder Alarm. At about the same time, a communication was sent of the perceived threat, and a group of men left on horseback to investigate the happenings at the British camp. They reported that there was no movement there. In the meantime, a message that men were shot in Boston by the British was carried through Connecticut to New York by September 5 and the next day to Philadelphia, where the First Continental Congress was held on September 6. The Congress, with Joseph Palmer, planned for a network of couriers to transport messages throughout the colonies. A Committee of safety was formed in October 1774 to evaluate the need for alarms and set them in motion. Its eleven members at the beginning of 1775 were Benjamin Church, Richard Devens, Jabez Fisher, John Hancock, William Heath, Azor Orne, Joseph Palmer, John Pigeon, Joseph Warren, Abraham Watson, and Benjamin White.

Realizing the ramifications of a communication going out that would result in men being mustered and commencing to fight, Joseph Hawley, a member of the Massachusetts Provincial Congress, wrote on February 22, 1775,

Initial rides


At about 10:00 p.m., the night of April 18, 1775, Joseph Warren asked Paul Revere to contact John Hancock and Samuel Adams in Lexington about the movement of British troops. Warren and Hancock were members of the Committee of safety and Revere had been watching the British troops movements as part of a committee of Boston and delivered messages for the Committee of safety. Warren also asked William Dawes to ride to Lexington.

During the nighttime ride to Lexington, Revere ensured that men in Charlestown sent lantern signals to alarm neighboring colonists that the British were coming. He learned from Richard Devens, another safety committee member, that ten British officers had been on the road leaving Lexington. He notified the captain of the militia men at Medford and alarmed others on his way to Lexington.

After meeting with Adams and Hancock, Revere and Dawes set off to warn colonists in Concord. They preceded the British, led by General Thomas Gage, as they marched to Concord to destroy patriots' stores of military weapons and equipment. Responding to the call to arms, colonists went to Concord and fought the British.

Dispatches sent beginning April 19
On April 19, 1775, Joseph Palmer of the Committee of Safety issued a dispatch to be carried by post riders, men who delivered mail throughout the colonies. The purpose of the call to arms was to have militias in five colonies rally to support the minutemen of the Massachusetts militia.



A number of post riders carried the "Lexington Alarm" message throughout a network of mail routes in Massachusetts, Connecticut, Rhode Island, and New Hampshire.

Isaac Bissell delivered the message west of Worcester to Springfield, Massachusetts, south to Hartford, Connecticut and in other areas in the state over six days.

Israel Bissell (no known relationship) conveyed the message to Worcester, Massachusetts, throughout eastern and southern Connecticut to New York City, New Jersey, and Philadelphia. Copies of the manuscript, handbills, and newspapers were circulated to other locations, like Maryland, North Carolina, and other areas.

Postriders rode through bad weather, poor road conditions, and moonless nights, which controlled whether they were able to travel three to five miles an hour.

Continued circulation
A copy reached Baltimore, Maryland, on April 26, where Mary Katherine Goddard printed the verbiage in the Baltimore Adviser and the Maryland Journal. It was printed in the Maryland Gazetter the following day in Annapolis, Maryland. On April 29, Alexander Purdie printed the message in the Virginia Gazette in Williamsburg, Virginia.

Another copy of the dispatch went to New Bern, North Carolina, where it was endorsed, and another to Charleston, South Carolina. The message was spread to other towns in Virginia, North Carolina, and South Carolina in May.

Subsequent messages
Updates provided information about the continuance of fights against the British and related news. New York communicated that martial law was implemented due to riots due to the outbreak of the war. Shipping became unsafe for Baltimore and other areas.
