Retreat and Rearguard Somme 1918: The Fifth Army Retreat

This is about Kaiserschlact, but specifically about the Fifth Army's retreat back across the old Somme battlefields in late March 1918. The area the subject of this book is from St. Leger in the north to La Fere in the south. The author describes individual battles in some detail, and he also examines the invaluable work performed by the Royal Engineers in blowing bridges and disrupting the lines of communications for the Germans.
