I recently came across this plan of the Casualty Clearing Station at Lillers in France, some fifteen miles behind the front lines, and thought it worth sharing. The lists at the bottom suggest that by late 1917 there had been a huge increase in casualties from illness and self-inflicted wounds, and you will also note a whole row of tents reserved for those requiring dental treatment. Army rations had much to answer for.
Happy Christmas all. See you in 2013.
