Courts Martial Records

Courts martial are legal bodies convened to determine the guilt or innocence of accused military men and women.

Courts martial had the authority to try a wide range of military offences that resembled civilian crimes like fraud, theft or perjury. Others, like desertion and cowardice were purely military crimes. Military offences are defined in the British Army Act.

A panel of officers sat in judgement at a court-martial, while the accused was represented by an officer who may be a military lawyer.

Punishment for military offences ranged from fines and imprisonment to execution.

Offences, punishment, and instructions on how to run a court martial are explained in the Manual of Military Law, which was distributed to Canadian Expeditionary Force units.

Records of individual courts martial consist of an average of 20 to 25 documents, many of which are standardized forms. These document the trial and the charges under the Army Act.

These records identify the officers who sat in judgement, and the evidence presented in court including statements by the accused and witnesses. In cases of conviction, the records document the sentence. Many records include formal rulings by the Judge Advocate General, who is the senior officer responsible for military justice.

The Search Screen

The search screen contains the following fields:

  • Name
  • Regimental number

Search Tips

  • Be careful when using regimental numbers. For example, if you type 222044, you will obtain only one reference. Officers did not have a regimental number unless they enlisted first as privates or non-commissioned officers.
  • If you did not find the person by name, you can try searching variations of the spelling or combinations of given names and initials (e.g. Simpson, Harold or Simpson, H* or Simpson*).
