As with the previous Swabian Circle Infantry Regiment flags I posted, I have absolutely no information on the operational use of these troops in the War of the Spanish Succession and the little uniform information I have seems fairly confusing, so all I can offer here is this sheet of flags; they are attractive flags, anyway!
The Brandenburg Onolzbach battalion flag was captured by the French at Friedlingen in 1702, which is why we know its design. Oddly I cannot find it in the Triomphes Louis XIV MS which I have (as a PDF from a French official source), despite that MS recording some flags captured at Friedlingen. I suspect there may be two different versions of the Triomphes as I have seen for sale a version online that appears to have different flags. As so often in this subject, there are frequently more questions than answers!
