That's an excellent mod, I've only just bought First Eagles, it definitely makes it more interesting.
The only 2 battles I know of was Cambrai which is slightly East of Arras. This was the first big tank battle of the war. August 1917 was when JG1 received the first of the Triplanes, 2 to start off with, Richtofen and Voss flying them. During September No 43 Squadron had Camels, No 28 had Camels and No 84 had SE5as.
