"To the uninitiated-as were we in those days when we returned to the Somme, too late to see the tanks make their first dramatic entrance-the name conjures up a picture of an iron monster, breathing fire and exhaling bullets and shells, hurling itself against the enemy, unassailable by man and impervious to the most deadly engines of war; sublime, indeed, in its expression of indomitable power and resolution.
