Ranging Board - German, Messines, World War I, 1917 Reg. No: ST 041645
- Alternative Name(s): Range Board, Artillery Board, Battery Board, Artillery Map Board
Quadrant of wood with map of Messines area, World War I. Used by a German officer in charge of a Heavy Mortar Battery against 2nd Anzac Corps at Messines. Inscribed on reverse with words including 'Ansbach' (a city in Bavaria) and 'Kartenstelle III' (a German military division), a possible reference to the division that used the board and its place of origin.
Ranging boards were used by artillery units to show the range of a gun in a placement overlooking the enemy trenches. They also detailed the position of the gun itself and the enemy trenches, entanglements and other features. In this instance the board depicts the area around 'Wulverghem' (today 'Wulvergem') in Belgium before the Battle of Messines in 1917.
The board appears to have been created for a 'Minenwerfer' - 'mine-thrower' or short-ranger mortar. The exact type of Minenwerfer remains unknown as all three calibres of Minenwerfer had a similar range. The location of the Minenwerfer is shown on the board by a red circle near the top right corner, next to arrows indicating geographic and magnetic north. The magnetic variance between the two north points is 13°21'; magnetic north would have been the point from which 0° was calculated.
The board uses angular mils, a form of measurement whereby 6400 mils = a circle for its bearings and the outer bearing arc is graduated at 5 mil intervals. Possibly due to the Minenwerfer's dual sights, the bearings have been marked using the centre of the board itself rather than a direct bearing.
Contemporary photographs indicate that a range arm would have been attached to the board by a pin at the Minenwerfer's position; however, this board does not have an arm.
According to accounts of the Battle of Messines, the Minenwerfer's position would have been overrun by the afternoon of 7 June 1917. An inscription on the back indicates that the board eventually passed into the possession of a 'Lieutenant Stuart' of the 2nd Australian Topographical Section. Subsequent research has shown that Lieutenant's surname has been spelt incorrectly that the inscription actually refers to William Alexander Stewart.
William enlisted in November 1914 with the 1st Divisional Supply Column before transferring to the 2nd Australian Topographical Section in February 1917. He eventually returned to Australian in January 1919 and was reunited with his wife, Marion, and their two children, Judith and Kenneth. William died in October 1949.
