The Valley Campaign, Chancellorsville, Fredricksburg, Seven Days Battles.

Do you mean the Seven Days Battles at the end of the Peninsula campaign?

Robert E. Lee

There is no such thing as a W campaign star. I'm assuming you mean with a campaign star. Each star represents a campaign that soldier was a part of for a minimum of 30 consecutive days or (I think) 90 nonconsecutive days. There are seven campaign stars authorized. There will never be any more so it's over. What you have is what you have and you can't get any more.

The seven days battles were a successful campaign by Robert E. Lee to drive the Union army away from Richmond, Virginia in summer 1862.

The Seven Days Battles was the number of battles in the Peninsula campaign under George B McClellan.
