WW1 British Manuals German INT Captures (G1038)

Rare Matched Pair of WWI British Tactical Manuals – German Intelligence Captured (June 1918)
A fascinating and highly collectible pair of original World War I British military manuals captured and utilized as intelligence assets by the Imperial German Army. Both documents feature matching, identical field inscriptions in period German cursive script: "geh. Romain Juni 18" (Secret – Romain Sector, June 1918). This verified shared provenance confirms they were overrun and processed into German files during the historic 1918 Spring Offensives on the Western Front, later preserved within a Bavarian veteran's estate group.
• Item 1: Notes on Trench Warfare for Infantry Officers: Revised Diagrams (Issued by the General Staff, December 1916; Printed London, 1917). Contains updated schematic blueprints and engineering layouts designed to fortify frontline trenches against artillery. Explicitly marked "For Official Use Only".
• Item 2: The Training and Employment of Platoons, 1918 [S.S. 143] (Issued by the General Staff, February 1918). Rare Theater Printing: Explicitly marked "Printed in France by Army Printing and Stationery Services" for direct distribution to frontline officers. Outlines the ultimate tactical evolution of British small-unit assault doctrine. Features an authentic hand-stamped/inked "O C" (Officer Commanding) marking on the cover.
Condition: Good, authentic battlefield-used condition. The softcover paper wraps show expected age-toning, minor creasing, and typical rust-bleeding from the original binding staples. Text and diagrams remain entirely complete, tight, and fully legible.
