GOOD CONDUCT PAY
The following information is quoted from Grierson (1899):
"For good conduct, which means, that the soldier has never been punished, he receives further extra pay (Good Conduct Pay). The daily rate amounts to 1d. The recipient wears a badge in the shape of a ^, pointing upwards, on the lower sleeve of the left arm. The first of these badges is awarded after 2, the second after 6, and the third up to the sixth respectively after 12, 18, 23, and 28 years of service. Every badge brings an extra penny a day. In case of punishment the soldier forfeits this extra pay or a part of it, but can recover it by good conduct. These extra payments and badges are only awarded to men from the corporal downward."
Over the years during the Victorian period there were several sets of rules governing the award of Good Conduct badges as shown below:
