[Original Secret Manuscript First World War Western Front Trench map showing the position at Zero Hour on the First Day of the Battle of the Somme, 1 July 1916. III. Corps sector - La Boiselle]


A rare original manuscript First World War operational trench map showing the British III Corps fire line at Zero Hour (7.30 a.m.) on 1 July 1916, prepared for the opening of the Somme Offensive—the bloodiest day in British military history. The map delineates front, support, reserve, and communication trenches around La Boisselle, including Tara Redoubt, Usna Line, Dundee Avenue, Lochnagar Street, and the Lochnagar mine tunnel and crater. These trench names and features fix compilation to the final week of June 1916, immediately before the assault: Tara and Usna Lines were completed in April; Lochnagar Street and the mine galleries were finalised by late June; and Dundee Avenue was among the new assembly trenches dug for the attack itself. Pencil annotations in a different hand—including “Charing Cross” and the precise alignment of the Lochnagar tunnel and crater—were likely added in the field on or soon after Zero Hour, when the Lochnagar mine was fired beneath German positions. Produced in ink on official linen-backed field map paper by draughtsmen of the Topographical Section, General Staff (Royal Engineers Field Survey Company, III Corps). A primary operational document from the fateful morning of 1 July 1916.

Condition Guide

We assess the condition of each item using three categories: Good, Fair, and Poor. We strive to ensure that any significant flaws are clearly shown in the images provided and detailed in the accompanying condition statement.

Good

The item presents well, with no significant flaws, and is in frameable condition. Minor imperfections—such as light spotting or offsetting, small blemishes, tight margins, neatly repaired tears, or discreet/professionally executed restoration—do not materially detract from its overall appearance.

Fair

The item shows noticeable flaws but remains in frameable condition. Some buyers may feel these imperfections affect its visual appeal. Typical issues may include more prominent spotting, blemishes, bleed-through from the reverse, obvious offsetting, visible or extensive restoration, wear along fold lines or junctures, small wormholes, trimmed or closely cropped edges, or less carefully executed repairs.

Poor

The item has major flaws that significantly impact its presentation and/or suitability for framing. These may include heavy spotting, staining, bleed-through, offsetting, unrepaired damage, or poorly executed repairs such as tears, holes, or areas of paper loss (including within the printed image). The item may also be fragile and prone to further deterioration.
