Small scale misdemeanours
These crimes included everything from matters of individual presentation such as being unshaven, untidy or losing kit; not saluting or addressing superiors correctly; dirty or incorrect equipment; being late on parade or after curfew, etc. They would be detected and dealt with by the NCOs and officers of a man's own unit. NCOs often gave men extra fatigues or exercise as punishment for small matters. Being confined to barracks or losing a day's pay was a torment too, for men who were eager for rest and amusement.
Moderately serious offences
For moderately serious crimes, a man could elect to be tried by a district court-martial, or be 'convicted' and sentenced by his Commanding Officer. The CO could sanction maximum punishments as follows: detention up to 28 days; field punishment up to 28 days; forfeit of all pay up to 28 days; for drunkenness, a fine up to 10 shillings. The CO could inflict minor punishments, with the offender having no right to a court-martial: confinement to camp for up to 14 days; extra guard duty; reprimand, severe reprimand or admonition.
Serious matters
These were tried by Courts-Martial. Some of these offences were ones that would have been tried by a civilian court if the man had not been on active service e.g. murder or rape. Other offences were purely military in nature, such as desertion.

Notes to this table: (1) offences where cashiering is shown as maximum punishment applied to officers only; (2) in order to enable a court-martial to award a field punishment, it was essential to allege 'when on active service'.
The courts-martial process was meant to be thorough, well-documented and carried out in accordance with law expressed in the Army Act which was subject to annual re-consideration by Parliament. Men on trial were supposed to be represented, and much evidence gathered and considered. In practice, especially at times of stress due to action, both of these principles were ignored or only barely adhered to. Documentation was often scanty, the process quick; men were often not represented, and indeed were often tried by officers of their own regiment or corps.
Officers could only be tried by GCM or FGCM. NCOs above rank of Corporal could not be tried by a court inferior to a DCM
The Outcomes of Courts
Martial
In all, 5,952 officers and 298,310 other ranks
were court-martialled. This amounts to just over 3% of the total of men
who joined the army.
Of those tried, 89% were convicted; 8% acquitted; the rest were either convicted without the conviction being confirmed or with it being subsequently quashed.
Of those convicted, 30% were for absence without leave; 15% for drunkenness;14% for desertion (although only 3% were actually in the field at the time); 11% for insubordination; 11% for loss of army property, and the remaining 19% for various other crimes.
The main punishments applied
were : 3 months detention in a military compound - 24%; Field Punishment
Number 1 - 22%; Fines - 12%; 6 months detention - 10%; reduction in rank
- 10%; Field Punishment Number 2 - 8%.
3.080 men (1.1% of those convicted) were sentenced
to death. Of these, 89% were reprieved and the sentence converted to a
different one. 346 men were executed. Their crimes included desertion -
266; murder - 37; cowardice in the face of the enemy - 18; quitting
their post - 7; striking or showing violence to their superiors - 6;
disobedience - 5; mutiny - 3; sleeping at post - 2; casting away arms -
2. Of the 346, 91 were already under a suspended sentence from an
earlier conviction (40 of these a suspended death sentence).
Field punishments
Field Punishment Number 1
This consisted of the convicted man being shackled in irons and secured to a fixed object, often a gun wheel or similar. He could only be thus fixed for up to 2 hours in 24, and not for more than 3 days in 4, or for more than 21 days in his sentence. This punishment was often known as 'crucifixion' and due to its humiliating nature was viewed by many Tommies as unfair.
Field Punishment Number 2
This
was similar to Field Punishment Number 1 except
the man was shackled but not fixed to anything. Both forms were carried
out by the office of the Provost-Marshal, unless his unit was officially
on the move when it would be carried out regimentally i.e. by his own
unit.
Military Police
Military Police matters came under the office of
the Adjutant-General. On his behalf, the Provost-Marshal supervised
military police duties of the army in the field. At each level of the
army hierarchy, the AG and the PM were represented. Each infantry
Division, for example, had an Assistant Provost-Marshal, who received
orders from the Divisional Assistant Adjutant-General, and who was
responsible for organising the police under his command. The military
police ('redcaps' from the red cover around their service cap) were
responsible for arresting all persons found without passes, plundering,
making unlawful requisitions, or committing offences of any kind. They
were also responsible for collecting stragglers, and for guarding
against spies. In case of emergency they could call upon any troops in
the vicinity to supply guards, sentries or patrols. In the Indian Army,
the Provost-Marshal could order corporal punishment without trial, of up
to 30 lashes.
