Mr. Smith, I appreciate your help. But first: I read in the forum instructions that you are not supposed to put illustrations in your post. How were you able to do this? Here is a link that I found in black and white. http://www.xenophon-mil.org/rusarmy/alex1/alexander%20army.htm.
I guess my bottom line question is that if I found an illustration of a flag for a grenadier or line (Musketeer) regiment, I could assume that at least one of the grenadier battalions would be carrying one like it. I am not looking at the white flags. Not only guard regiments.
If you don't mind, how am I able to look at the illustrations that are referenced in the link you put in your reply?
Again, thank you for the trouble you took to answer my question.
PS Also, do all (most) Russian infantry grenadiers battalions wear the shako with the "bottle brush" plumes?
PPS Please do not do very much research on this. I know that your time is valuable. I wish that I knew enough to actually contribute to this forum.
