This is battlemap that was used to set up the table. The map was created from original trench maps, supplemented by information from British and German primary sources. The red dotted line marked the British front line trenches; blue dotted line for the German equivalent. Despite the name, Layes Brook is actually quite deep and requires one turn for stands to cross. Details of the scenario, including the TO&Es, are available on the Great War Spearhead Yahoo Group here.
