Two track plates with a 'grouser' attached, British Mark II tank : Bullecourt

Two track plates to which is bolted a spud or grouser attachment. A pair of track guides are rivetted to the reverse. There is no movement remaining between the track plates. Corroded.

This is part of the remains of one of the dozen or so Mark II British tanks meant to support the Australian infantry (the 4th and 12th Brigades of the 4th Australian Division) at the First Battle of Bullecourt (10-11 April 1917). Their use was seized on by commander of the British 5th Army Sir Hubert Gough, in his rushed planning for the assault, in lieu of artillery. The tanks were meant to lead and protect the infantry in their assault on the heavily fortified village of Bullecourt which formed part of the Hindenburg Line; instead, seven broke down on their way to the starting line and the remainder were quickly knocked out, leaving the Australians exposed, without artillery support and the German wire entanglements unbroken. Despite capturing section of the German lines, they were forced to retire with 3,300 casualties, including over 1,100 taken prisoner.

This pair of track links from a British Mark II tank are fitted with a rare 'spud' or 'grouser' attachment which were designed to widen a tank track's capabilities and provide more bite into the ground. This item was recovered from the Bullecourt area by local residents. The manufacturers for the Mark II series of tanks were either Foster & Co (which built 25 male tanks); or Metropolitan (which built 25 female versions).
