Treaty of Westminster 1674

 In the interest of finding out what occurred 350 years ago in the Franco-Dutch war we are now in the post Treaty of Westminster which ended British involvement in the war. Except it didn't. Some came back but some regiments like the Ryal English stayed in the French army and were still recruiting in Britain and Ireland. See more

Cavalry officer 1680

 Anyone know what regiment he was in?

Thomas Lucy (1655–1684).
Artist:  Godfrey Kneller.
Year 1680

From the National Trust

Oil painting on canvas, Captain Thomas Lucy (c.1655-1684) and an unidentified enslaved groom by Godfrey Kneller (Lubeck 1646/9 – London 1723), signed and dated G. Kneller (GK in monogram) f.1680. A full-length portrait with Captain Thomas Lucy positioned slightly to the left and a black groom to the right. Lucy is wearing long buff-coloured jerkin with blue and gold embroidered cuffs, white and orange silk fringed sash, lace jabot and hat held in left hand. The groom, controlling a horse, has a metal collar around his neck and is dressed in blue and scarlet. A troop of cavalry can be discerned in the background. Captain Thomas Lucy (c.1655–84) inherited Charlecote in 1677 and served as Captain of the Household Guards during the Dutch Wars of the 1670s. Note on the unidentified groom: The unidentified groom wears a conspicuous metal collar, indicative of enslavement. It is not known if Kneller painted this unidentified figure from a model or if it is a portrait of a real groom in Captain Lucy's household.

 Biog

On 10 feb 1673 a composite troop of cavalry was taken from the three troops of the Life Guards and sent to France under the command of Louis de Duras, Marquis de Blanquefort. This special troop remained in France until 1674, although Duras stayed in France to command the English Brigade after that date. From here

 While on the subject of Restoration cavalry it would be churlish not to mention the Troop flying the flag for Baroque cavalry. Facebook page
