I just finished reading my newly arrived copy of “Fortifications of the Western Front 1914-1918” by Osprey, part of their Fortress series. This one got into the detail I was really looking for as far as how and why trenches were constructed and what their role on the battlefield was during this period. Well written and with pictures, original diagrams and drawings this one will give me a good start on building trench terrain for my foray into the Great War period. If you are giving thought on building a trench system for any period from WWI up this is an excellent resource.
Life is short, break the rules. Forgive quickly, kiss slowly. Love truly, laugh uncontrollably and never regret anything that makes you smile. - Samuel Longhorne Clemens (Mark Twain)
