Retreat and Rearguard, Somme 1918 [PDF ebook] 
The Fifth Army Retreat

The German Spring offensive or Kaiserschlacht was a period of great danger for the Allies. Both sides were exhausted after years of bitter fighting and huge losses. While eventually catastrophically unsuccessful and the prelude to their final defeat, the Germans forced the Allies back over hard-won ground until the tide turned.Historian Jerry Murland has researched and visited the scenes of desperate actions during late March 1918. He describes in graphic detail the battles fought by British, Irish and South African regiments in the area from St Leger in the North to La Fere in the South. He unearths the extraordinary stories of unit and individual courage. He also examines the work of the Royal Engineers who blew bridges and disrupted lines of communication. This original approach covers battles that in many cases have only been described briefly in official histories. The book is a useful companion for any battlefield visitor.
