Montauban. Parts of Sheets 57D S.E., 57C S.W., 62D N.E., 62C N.W. Trenches corrected to 2-6-16. Scale 1:20,000 [cover panel: Trench Map — Secret — Montauban. Scale 1:20,000.]


A British trench map marked up with artillery targets for the first night of the Somme's preliminary bombardment, 24–25 June 1916. Stamped SECRET and numbered Copy No. 5, its cover is inscribed 'Night U/V No. 5' above 'Barrage Points'. U and V denote 24 and 25 June: contemporary artillery orders and a dated diary corroborate this interpretation. The coloured manuscript marks allocate German positions and approaches to British and French weapons, explained by a handwritten key at upper right: heavy howitzers in red on Pommiers Redoubt and the Montauban defences; French 220 mm howitzers in black on the village and Glatz Redoubt; French 75s in blue; 60-pounders and 4.5-inch howitzers in green across Bernafay and Trônes Woods; 4.7-inch guns in yellow on Longueval and Guillemont; and 6-inch Mark VII guns in orange on Ginchy and, off the sheet, Combles. These marks identify targets, rather than the locations of the guns. The geography and Anglo-French artillery scheme are consistent with the XIII Corps sector. The cover's night designation links this copy to the opening bombardment a week before the infantry assault on 1 July. Montauban special sheet, G.S.G.S. 3188, at 1:20,000; trenches corrected to 2 June 1916. Folding and linen-backed.

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.
