Very impressed with this game, the level of research is excellent particularly as it is a period with less accessible sources than some others.
A couple of quick questions/points.
I notice that all the scenarios have the same dawn/dusk/night times. I was wondering whether the summer situation, in August and September, might be better represented with a shorter night period. Maybe 10pm to 4am with two 3 hour night turns. I have read a little about the earlier campaigns and a number of authors mention the long hot days, and their effect on operations.
I could be accused of being a bit nationalistic but I wonder if the British Territorials are a bit underrated as D's? They were pretty well trained and motivated and had considerable inter-reaction with their Regular counterparts. Some, especially the yeomanry, had also seen service in the Boer War.
I have a couple of connections with this campaign which might be of interest. My father's cousin was an officer in the RA and I have attached a couple of pictures. They are OP panoramas of the Ypres salient. I imagine they were coloured in after the battle when "out of the line".
In the mid-1980's I was the Battery Captain, or second in command, of L "Nery" Battery RHA, which of course won its Battle Honour on the 1st September 1914 winning three VCs in the process. I have attached a photo of a print of the picture the Battery commissioned in 1984 to mark the 70th anniversary of the battle. Incidentally the battery actually owned the three original medals won on that day!
