Thanks for all your help guys.
My only photo was of the reverse. Now knowing that LEE'S FARM is on the front and that the front is the same as the reverse, I am confident with this on the front and matching the same on the reverse.
SOUTH MOUNTAIN.......top
SHARPSBURG.............left
LEE'S FARM................right
FREDERICKSBURG......bottom
I have a jpeg image of what it will look like but see I can only post images here that are on the internet.
Without your help, this flag would have ended up differant, not knowing about LEE'S FARM, I would have guessed COLD HARBOR. If I had chose WILLIAMSBURG for the bottom instead of FREDERICKSBURG I may have even added SEVEN PINES to the top. This being because the top is completed missing and because of all the other Flags with that pattern, SEVEN PINES and WILLIAMSBURG.
Of course, having the top completed missing, we will never know what, if anything was on the top. I will leave the top empty.
Thanks to all of you again!
