The second battalion of La Reine in Canada carried the battalion colours (the upper colour) from 1755 until the 8th September 1760 "when General Levis ordered the colours to be burnt following the British refusal to grant the Honours of War as part of the terms of capitulation" (René Chartrand, "The French Soldier in Colonial America"). Dashed unsporting and ungentlemanly! (Of the British, that is... ;-))
Apparently only the single battalion regiment Angoumois carried its white colonel's colour in North America during the Seven Years War; the rest of the regular infantry carried only the regimental or battalion colours (
drapeaux d'ordonnance).
Unfortunately the blog does not allow me to post these flags as a vector file, which would be both a smaller file size and much more crisp and detailed.
