Okay, don't want to tantalise you (and myself) any longer: Hereby I proudly present my version of the Hessen-Kassel Jäger in British service.
The Jäger (litterally: huntsmen) were originally formed from actual hunters and woodsmen as units of skirmishing marksmen, able to fight in open order and on broken ground. As such the Jäger corps were regarded as elite troops, and became quite common among German principalities after the Seven Years' War. Of special fame are the "Hessian Jaegers" due to their employment by the British in the American War of Independence. Actually there were several Jäger Korps, 'lend' from several German (not only Hessian) princes. Best known are the "Greencoats" from the landgraviate of Hessen-Kassel, since one of their captains, Johann Ewald (1744-1813), wrote a personal account of the warfare in Amercia.
Also the Perrys portrayed Ewald as a captain in their "Hesse-Kassel Jaeger command" blister, readily identifiable by his eyepatch (Ewald lost an eye in a duel in 1770). I think it's one of the most characterful miniatures Alan has ever designed!
Accordingly, I painted the soldiers as members of the 1st company (white/red pompons). The green waistcoats made of wool were part of their 'official' uniform, and were worn mainly - and understandably - in cold weather. 'Summer dress' had a lighter waistcoat of buff or off-white colour.
Most of the miniatures are modelled wearing rather irregular (gaiter) trousers. Officially the Hessen-Kassel Jäger were equipped with (off-)white breeches, stockings and gaiters. Mounted Jäger substituted boots for the gaiters. (Here's my source.) So only the Ewald figure is clad 'by the book'. I painted some of the men's trousers with stripes. Admittedly, I have no evidence for that fashion among the Jäger other than an illustration by G. Embleton in R. May's "The British Army in North America"; and it's not even very likely. So, please take it as artistic license. ;)
All Jäger units were equipped with rifled guns, enabling them to take aimed shots. There were attempts to introduce such weapons (and according fighting techniques) to the British army as well. However, these trials were abandoned shortly after the American war, not to rise again until the Napoleonic Wars.
By talking to an experienced shooter I've been told that I painted the aiming figures with the wrong (the right) eye closed. Anyway, I don't want to alter that now, because I'm happy with my total inexperience in wielding guns.
Now I feel the strong need to paint a unit of the line again - too many elite troops around so far. Though, I've to admit, it's a great relief having to paint only two miniatures per base. To date I'm not sure what AWI stuff will be next - but if you have any suggestions or wishes, you're welcome to post them here.
