Not that this should be viewed as gospel and things may change, but here are MY plans for the Jacobite foot...
Irish Foot Guards (2 battalions)
Rear pike stands (total 4 stands each), models advancing
Earl of Clanrickarde
Central pike stand (total 3 stands), models shooting, apostles
Earl of Antrim
All musket (total 3 stands), models shooting, apostles
Marquis de Boisseleau (2 battalions)
Rear pike stands (total 4 stands each), models at rest
Irish Militia
All pikes (total 3 stands), models at rest
The last unit is partially because I want to paint a rabble unit. Some reports on the Boyne say there were seven Jacobite battalions, but I've only ever seen six named. Anyone else read that? Did Antrim or Clanrickard have two battalions? Anyway my seventh battalion is going to be a mob of pikes...
