The Austrian artillery arm didn't perform very well in the War of the Austrian Succession, and that lead to wholesale redesign of the ordnance to produce lighter guns that would be more maneuverable on the Field of Battle. In the Seven Years War, the new Austrian pieces were so admired that most other powers in Europe copied their designs; even Gribeauval had served with the Austrian artillery in the 7 years war, and was probably heavily influenced by the experience. Austrian artillerists received several years of training, and better pay than their infantry and cavalry brethren, at the price of a longer term of enlistment (14 years). By 1809, though, the once cutting edge Austrian guns had fallen somewhat behind the rest of Europe, especially the French.
Austrian artillery companies (batteries) came in five types by 1809 (not including siege units). The old 3 pounder regimental guns were discontinued, but the light guns still saw some use as 3 pounder Brigade batteries, usually of eight 3 pounder guns each. In addition, Grenz units sometimes retained their attached 3 pounder guns. There were three kinds of 6 pounder batteries. First were the 6 pounder Brigade batteries, which again had eight 6 pounder guns, and were generally assigned to Infantry Brigades. Second were the 6 pounder Position (or Support) batteries, which had four guns and two 7 pound Howitzers, and were generally assigned at the Divisional level. Third were the Cavalry Batteries, newly established in 1778, which also had four 6 pounder guns (of different and lighter design) and two 7 pound howitzers. They were generally assigned to cavalry Brigades or Divisions. Finally, each Corps generally had two or three 12 pounder Position (or Support) batteries, each of four guns and two howitzers, There was no Army Artillery Reserve, as there was in the French army.
With that background, we're going to proceed on a tour of the artillery and related support units of my miniature Austrian army.
Finallly, the pontooniers wore a medium to dark blue uniform (this time including the pants as well) with red facings, and once again the corsehut. There was also a battalion of Danube boat handlers raised from among the Grenz; by 1809 they wore a plain shako and a medium to dark blue jacket with red facings (pointed "Hungarian" cuffs with the "bear's paw" lace) and light blue Hungarian pants, complete with the yellow/black braid and knots.
A few more parting shots of some of my Austrian artillery... the lone officer is supposed to be Oberst Smola, "Father of the Austrian Artillery" of this era.
