Thomas Stafford, first duke of Buckingham was a loyal servant to the Lancastrian government of Henry VI. He had been prominent in the French wars of Henry VI's reign, defending the English possessions in Normandy. He had fought for the King at the first battle of St Albans in 1455; trying to mediate before the battle and being wounded as the Yorkist lords broke through the town defences (possibly whilst he was still arming). At Northampton he probably commanded the main battle and was killed in the fighting that ensued once Warwick had been allowed into the royal encampment following Ruthin's treachery.
Buckingham's figure is a slightly altered Perry metal commander - Henry Tudor - with a plastic sallet added and then metal plumes added to that. I have tried to give him a dark burnished harness with gold edging, to befit his status as the Lancastrian leader. The standard bearer on foot is an old Citadel Alcatini 'dogs of War' figure with a plastic helm added - these are useful figures as they're broadly based on late fifteenth centry armour, except for the helms, which can now be easily swopped for plastic Perry spares! You can usually pick them, as I did, on flea-bay.
Livery colours for Buckingham were black and red and his livery badges seem to have included a flaming wheel, white swan and stafford knot and so I have included elements of all of these in the command base, either on flags, standards or livery coats, just for good measure. Flags by Freezywater.
Now to make the short trip west - to complete Shrewsbury...
