Hello Armed Forces experts

Can anyone help me to find out more about the movements of my hubby's 4xg-grandfather, Jethro DOBSON, who was a soldier in the Berkshire Regiment of Fencible Cavalry or 'Windsor Foresters'?
He was born in Clewer in Berkshire, around 1774, and stationed in Montrose, Scotland by 1798 when he married local girl Elizabeth MEARNS (there are loads of other soldiers of the Windsor Foresters on the same page of the parish records). In 1799 they had a son, Jethro, born and baptised in Montrose, and their next child, David, was born in 1801 in 'Jersey Barracks', Jersey, CI (according to census returns). All children thereafter were born back in Clewer, Berks.
I have found a little bit of info online about the Windsor Foresters, who seem to have been sent to Scotland as reinforcements against French invasion etc. during the Napoleonic Wars...does anyone know where I could find out the movements of the regiment, when they were where, etc.?
I'd appreciate your advice

Many thanks
Prue
