'After weeks of weary fighting for the fateful Menin Road, the victors and the vanquished both happy', 1917

Stereoscopic photograph, World War One, Western Front (1914-1918), 1917.

Stereographs consist of two identical photographs paired in such a way that when seen through a special viewing instrument, a stereoscope, they appear as a three-dimensional images. By 1899 the photographs were mounted on thick card that was given a slight curvature to increase the illusion of depth.

A major operation during the Third Battle of Ypres and the drive towards Passchendaele, the Battle of Menin Road (20-25 September 1917) witnessed the first use of General Herbert Plumer's 'bite and hold' strategy. After repeatedly trying to break through on a wide front and being halted by the deep German defence system, Plumer instead selected a small part of the German front line. This would be heavily shelled and then attacked in strength. The advancing troops would stop once they had penetrated 1,500 yards into the German lines. At this point they would dig in, and another wave of attacking troops would pass through them to attack the next objective. The original attackers would then consolidate the ground they had taken, and become the new reserve for future advances.

Using this tactic became possible when more artillery was deployed, thanks partly to the ground drying out between late August and September. Additionally, it was enhanced by using more, better aircraft, carrying out close air support and air defence, contact-patrol, counter-attack patrol, artillery observation and ground-attack. It meant that British soldiers did not move beyond where they could be supported, and consolidated gains made.

This meant that when the German counter-attack was launched, instead of finding a mass of exhausted and disorganised men at the limit of the Allied advance, they would find a well organised defensive line still in range of supporting artillery.

The Menin Road operation was a success with most of Plumer's objectives being captured on the first day. German counter-attacks were repulsed the first and second days of the operation. Three quiet days followed. The battle ended with a final German counter-attack on 25 September, again repulsed without serious problems.
