Great uniform and order-of-battle analysis there, Flambeau. Thank you!

Large-scale paintings of battles in the first half of the C18th were often allegorical and painted to a commission, so the depiction of Blenheim here needs to bear in mind the questions (a) who was Wootton trying to impress/please and (b) who paid him to carry out this work? Candidates would clearly include the Georgian Royal Household and leading noblemen, including the House of the Duke of Marlborough.

Whatever the case, I'm now working out which unit of yellow-coated French dragoons will feature in my French WoSS armies!

Thank you, Minuteman.
That is indeed the crucial question with regard to most paintings. We have to keep in mind that these were commercial products, executed to please the client. So there's always the danger of something fanciful being added to the painting. That said, they remain a valuable source of information.
As to yellow dragoons: Lesparre were present at Oudenaarde, Listenois at Blenheim and Malplaquet, and Mestre de Camp Général at all four of Marlborough's major battles (if we assume they retained their old uniforms). Some time ago I made a list of all regiments that participated in these battles from the available orders of battle to see which ones I might paint, comes in handy :slightly_smiling_face:.
Letrun's book on the French dragoons (Vol. 1, 1669-1749) is a good source of information and well worth buying.
For anyone interested in something else here's a link to the order of battle of Almanza

Thank you Flambeau. I have literally, in the last couple of days, taken delivery of the Letrun book on French dragoons, and it is a gold-mine of information.

All we need now are some sets of Strelets French dragoons to purchase and paint!
