Here are my French Line Artillery, along with various parts of the logistic train, including bridges, supply wagons and ambulances. Not all of this is complete (the guns need a bit more work), but you get the picture.
What is interesting is to note just how much space artillery took up on the battlefield, once limbers and caissons are taken into account. Some have six horses, others only four, which by all accounts was the case in 1815.
The figures are converted Hat with Airfix heads, Hinton Hunt and Alberken, Art Miniaturen, Zvezda and the old Airfix figures, which stand the test of time even if the guns and limbers don't.
I have cheated a bit by including my Guard Train but not the Guard Artillery, which I will keep for another day.
