[Together, two volumes.] London: Thomas Nelson & Sons, n.d. [1916 & 1917]. Original paper-covered boards and original wrappers, respectively.
First Editions of Buchan's account of the war effort. Buchan had joined the Nelson publishing firm as literary adviser in 1905 (due in large part to his friendship with Oxford classmate Tommy Nelson -- killed in action in April 1917). These volumes are filled with maps and also with photographs of the Somme battle sites, including a number of action ones showing British soldiers "crossing the parapets," tanks overrunning obstacles, mines exploding, etc.
The first volume was bound in paper-covered heavy boards; the second was available (without priority) in either paper-covered thin boards or, as here, heavy wrappers. These are very good copies, with some edge-wear as would be expected on these fragile volumes; typically, both volumes are found with most of their spine paper lacking, but here most of it is present. Blanchard A40 & A41. Item #14129
