FRANCE: The officer in the photograph is trawling his way through knee-deep, wet mud, buried up to the top of his boots and half-way up his cane. MUDDY Hell: Shocking 100-year-old pictures show the quagmires which British troops in the First World War had to fight, live, and march through. Sobering images from the Great War show soldiers battling free a car entrenched in deep mud; a smiling trooper putting on a brave face as he examines his flooded dugout on the Front Line; and an exhausted mule presumably drawing its last breaths as French soldiers desperately try and pull the doomed beast out of a deluged shell hole. Another brutal shot, part of the National Library of Scotland???s online collection, shows a struggling soldier attempting to drag a large gun along a sodden railway track surrounded by bog.
