Payment of Wages in the Field

Does anyone know the method by which soldiers were paid in the War of 1812? My understanding is that they were usually paid late through the regimental paymaster but did their sergeants ever touch the money and was the remuneration in coin, gold, army script, or pound notes? Did the money arrive direct from the Royal Mint for British forces or perhaps the Boston Mint for American soldiers? At some point it wound have to have been transported by wagon or perhaps mule to someone who could approve its distribution. Any ideas would be helpful.

Thanks for your assistance,

Tom Taylor
