Here is  a copy of a letter sent home by Pte 112296 James Malarkie Tank Corps and his tank called Newtongrange

He describes it in a very matter of fact manner, but this is  his part in the Battle of Amiens, which started on 8th August 1918. The battle was launched with the aid of over 400 tanks. It petered out after a few days but was the start of the final 100 days advance of the allied armies.

For the action described Pte. James, William Malarkie (No.112296) was awarded the Military Medal.

"For gallantry, determination, and devotion to duty during the advance from Villers-Bretonneux to Meharicourt on August 8 and 9. This man drove with great coolness and skill throughout these days.

Though suffering severely from cramp he refused to be relieved. In the action of the 9th he showed much skill and judgement in manoeuvring his tank so as to enable the crew to fire at the different targets. He also kept the crew informed of the position of our infantry, and set a splendid example of determination and devotion to duty."

The citation gives his battalion as being No.14. The battalions were all identified by a sequential letter of the alphabet prior to the end of 1917 and, because of this, generally named their tanks with a name that started with their battalion letter. This practice continued after the battalions were numbered and the name "Newtongrange" fits in nicely with this convention

I am obliged to Ian Verrinder of the Great War Forun for assisting  with information.
