The Yost Post · The Lexington Alarm of 1775
On April 19, 1775, the Lexington Alarm brought hundreds of Massachusetts militia companies into motion, including many whose men never reached the fighting.
As warnings spread through the countryside, militia officers summoned their men, minute companies assembled, and communities prepared to respond to the British expedition toward Concord. Some companies marched directly toward the conflict. Others received the news later, assembled at regimental gathering places, or traveled toward Cambridge after the fighting had ended.
This collection examines the towns that mobilized, the companies that answered the alarm, and the surviving records of their service. Its purpose is to document the wider military response rather than recount the battlefield engagements themselves.

1. The Extent of the Mobilization
When news of the British march spread through Massachusetts, the response was not limited to Lexington, Concord, or the towns immediately surrounding them. The alarm reached communities across eastern and central Massachusetts, activating local military organizations that had spent the preceding months preparing for an emergency.
Frank Warren Coburn’s 1912 compilation of militia muster rolls provides an important starting point for identifying the companies associated with April 19. Its index contains 27 town headings, although one heading uses the later name Arlington for Menotomy, then part of Cambridge. The compilation is valuable but does not encompass the entire provincial mobilization.
A broader statewide study published in 1976 identified 440 companies that marched in response to the Lexington Alarm. The figures, reproduced in a later historical report concerning Westborough, demonstrate the scale of the military response beyond the companies involved in the immediate fighting.
Statewide Mobilization440 companies identified as having marched in response to the Lexington Alarm, according to the 1976 statewide study as reported by David A. Nourse.
| Company Classification | Companies |
|---|---|
| Minute companies | 162 |
| Regular militia companies | 111 |
| Alarm-list companies | 11 |
| Classification unspecified | 156 |
| Total | 440 |
Research qualification: The statewide figures are reported in Nourse’s 2021 study. The original 1976 compilation has not yet been directly examined for this directory. The town listings below are therefore an initial research inventory, not a claim that every responding company has been identified.
2. Understanding the Militia Companies
Massachusetts did not depend upon a single type of military company in 1775. Its military establishment included ordinary militia companies, selected minute companies organized for rapid response, and alarm-list organizations drawn from men outside the principal militia establishment.
Minute companies were expected to assemble quickly when summoned. Regular militia companies represented the broader military organization of the towns. Alarm-list companies provided another means of drawing upon available manpower in an emergency. The precise organization and service of any individual company must be established from its own records.
These distinctions matter because the popular term minuteman is often applied loosely to men who answered the Lexington Alarm. Not every responding soldier belonged to a minute company, and the historical record should preserve the difference.
Important DistinctionAnswering the alarm, marching toward the gathering provincial forces, and participating in the fighting were three different experiences. A company’s documented mobilization does not necessarily establish battlefield participation.
3. Town & Militia Company Directory
The following directory reproduces the town and company entries identified in Coburn’s muster-roll index, arranged alphabetically for reference. Company names follow the source’s naming conventions. The entries provide research leads for reconstructing local mobilization and identifying individual officers and soldiers.
Several entries require particular caution. Menotomy was not a separate town in 1775, and Locke’s company appears under both Arlington and Cambridge in the index. Some companies lack complete surviving rolls. These issues must be resolved before a definitive statewide count of distinct companies can be prepared.
A–C: Acton through Concord
| Town | Company Entries |
|---|---|
| Acton | Davis; Hunt; Robins |
| Arlington (Menotomy) | Locke |
| Bedford | Moore; Wilson |
| Beverly | Dodge; Thorndike; Shaw |
| Billerica | Crosby; Farmer; Stickney |
| Brookline | White; Aspinwall; Gardner |
| Cambridge | Locke; Thatcher |
| Chelmsford | Barron; Parker |
| Concord | Brown; Miles; Minot; Barrett |
Historical boundary note: Menotomy was part of Cambridge in 1775. Its later designation as Arlington is retained here only to help modern readers locate the community. Locke’s company is duplicated in Coburn’s index and must not be treated as two separate units.
D–L: Danvers through Lynn
| Town | Company Entries |
|---|---|
| Danvers | Epes; Flint; Hutchinson; Lowe; Page; Prince; Edmund Putnam; John Putnam |
| Dedham | Battle; Bullard; Draper; Ellis; Fairbanks; Fuller; Gould; Guild |
| Dracut | Coburn; Russell |
| Framingham | Edget; Emes; Gleason |
| Lexington | Parker |
| Lincoln | Smith |
| Lynn | Bancroft; Farrington; Mansfield; Newhall; Parker |
Dracut illustrates why the directory must include companies that did not reach the fighting. Captains Peter Coburn and Stephen Russell are associated with the town’s response to the alarm, although their men arrived too late to participate in the engagement. Their mobilization nevertheless formed part of the wider provincial response.
M–R: Malden through Roxbury
| Town | Company Entries |
|---|---|
| Malden | Blaney |
| Medford | Hall |
| Needham | Aaron Smith; Robert Smith; Kingsbery |
| Newton | Cook/Marean; Fuller; Wisswall |
| Reading | Bacheller; Eaton; Flint; Walton |
| Roxbury | Child; Draper; Whiting |
Company identification: The Cook/Marean entry for Newton refers to one company rather than two distinct units. Changes in command or alternative officer names should not automatically be interpreted as evidence of separate companies.
S–W: Stow through Woburn
| Town | Company Entries |
|---|---|
| Stow | Whitcom |
| Sudbury | Cudworth; Haynes; Locker; Nixon; Smith; Stone |
| Watertown | Barnard |
| Westford | Bates; Minot; Parker |
| Woburn | Belknap; Fox; Walker |
Stow and Westford, like Dracut, demonstrate the difference between answering the alarm and reaching the fighting in time. Their companies belong in a study of militia mobilization even where the surviving accounts place their arrival after the engagement.
4. Westborough: Three Companies Answer the Alarm
Documented MobilizationWestborough, Worcester County — three companies comprising 101 men marched toward Cambridge in response to the Lexington Alarm.
Westborough provides a particularly useful example of the militia response beyond the battlefield. The town’s surviving military records establish that three companies answered the alarm and marched toward Cambridge, approximately thirty miles away.
Historian David A. Nourse’s 2021 report identifies one minute company and two regular militia companies. Together they comprised 101 men. Their service is supported by muster and pay rolls preserved in the Massachusetts Archives.
| Commanding Officer | Company | Men |
|---|---|---|
| Captain Edmund Brigham | Minute company | 46 |
| Captain Seth Morse | Militia company | 34 |
| Captain George Baker | Militia company | 21 |
| Total | Three companies | 101 |
These companies did not participate in the fighting at Lexington and Concord, but their response demonstrates how communities farther from the immediate crisis committed men to the provincial military effort. The Westborough example also illustrates why a directory limited to battlefield participants would overlook an important part of the historical record.
5. Additional Communities Under Investigation
The town directory above is only an initial inventory. Other communities appear in local histories, accounts of the alarm’s transmission, and descriptions of militia orders. Some are associated with named companies, while others are known primarily as places where warnings arrived or troops were directed to assemble.
The following entries are research leads. They should not be treated as fully verified company musters until supporting military records have been examined.
| Community | Present Evidence or Research Lead |
|---|---|
| Harvard | Local historical accounts associate Captain Jonathan Davis’s minute company with a march toward Cambridge. Original muster verification remains necessary. |
| Sutton | Captain Daniel Bucknam Jr.’s company is associated with the response to the alarm. Its classification and service records require examination. |
| Tewksbury | Coburn describes the alarm reaching the community and continuing toward Dracut. The town’s company muster remains to be established. |
| Pepperell | Companies were reportedly ordered toward Groton for regimental assembly. Their identities and service must be verified. |
| Groton | Appears as an assembly destination. The town’s own militia response must be distinguished from its role as a gathering place. |
| Littleton | The alarm reportedly reached the town during the morning of April 19. The organized militia response requires further documentation. |
| Hollis, New Hampshire | Appears in accounts of orders to assemble at Groton. Its response belongs to a separate study of communities outside Massachusetts. |
Research status: Receiving the alarm, assembling militia, and marching toward a destination are separate historical claims. Where the available source establishes only the receipt of a warning or an order to assemble, this directory does not assume that a particular company completed a march.
6. What the Muster Rolls Can Reveal
Muster and pay rolls are among the most important surviving records for reconstructing the Lexington Alarm. They may identify a commanding officer, enlisted men, dates of service, travel allowances, and the compensation claimed for military duty.
Yet these records must be interpreted with care. Some were prepared after the events of April 19, often for administrative or financial purposes. A roll documenting a period of service does not necessarily establish the precise number of men standing at the original assembly point, nor does it prove that every listed soldier reached a particular location at the same time.
The most reliable reconstruction combines military records with town meeting proceedings, contemporary correspondence, officers’ accounts, and other documents that help establish when a community received the alarm and how its men responded.
Questions for Each TownWhen did the alarm arrive? Which companies assembled? Who commanded them? How many men are documented? Where were they ordered to march? What evidence survives of their subsequent service?
7. Researching an Ancestor Who Answered the Alarm
For family historians, the Lexington Alarm offers an opportunity to investigate military service at the community level. An ancestor may have belonged to a minute company, served in the regular militia, answered an alarm-list summons, or assisted a town’s preparations without taking part in the fighting.
The first task is to establish the ancestor’s residence and identify the military companies organized in that community. From there, surviving muster and pay rolls can be examined for the individual’s name, commanding officer, and recorded period of service. Town histories may provide useful leads, but claims of personal participation should ultimately be connected to identifiable evidence.
The statewide compilation Massachusetts Soldiers and Sailors of the Revolutionary War is another useful research tool. Its entries can help connect individual soldiers with officers and military service, although those entries must still be interpreted in relation to the particular alarm and company under investigation.
A note for family researchers: Residence in a town that mobilized does not prove that an ancestor answered the Lexington Alarm. Likewise, service in a company during the Revolutionary War does not automatically establish participation on April 19, 1775. Each conclusion should be supported by records appropriate to the specific claim.

Historical and Genealogical Research Note: This article is an original historical synthesis based on published muster-roll compilations, local historical research, and references to surviving military records. It is not a complete statewide roster of the Lexington Alarm. The initial town directory reflects Coburn’s indexed entries, while Westborough and the additional research leads demonstrate the broader scope of the mobilization. Duplicate company entries, incomplete rolls, historical town boundaries, and differences between documented assembly and actual military service require continuing investigation. Inclusion in this collection does not establish that a company or individual participated in the fighting at Lexington and Concord.
