- Diagram Showing Adaptation to the 'Large-Wheeled Tractor' Idea
The genesis of the “large-wheeled tractor” was as follows: Trenches with a parados and parapet about 4 ft. high were being constructed by the enemy in Flanders. The engineers consulted by the Land Ship Committee gave it as their considered opinion that if these obstacles were to be crossed, a wheel of not less than 15 ft. diameter would be necessary. Machines with these gigantic wheels were actually ordered, but the wooden model that was knocked together as a preliminary at once convinced even its best friends that the design was fantastic, and that any machine of the kind would be little better than useless on account of its conspicuousness and vulnerability. However, the “big wheel” idea did not utterly die, for in the upturned snout of the Mark I. Tank we have, as it were, its “toe” preserved, the track turning sharply back at about axle level, instead of mounting uselessly skyward, as would have been the case had not the old wheel idea been supplanted by that of the sliding track. - Map of Tank Operations, August–November, 1918

Doubtless on the coasts of Scandinavia and North Germany, the chief home of these composite crossbows after the time of the Crusades, whalebone was easily obtainable, whilst in other parts of the Continent, the pieces which formed the heart of the bow, were made from the straightened horn of an animal. This ancient form of crossbow with a composite bow, survived in an improved form in Scandinavia and in the north of Europe, as a weapon of sport and war, till about 1460, or for nearly a hundred years after the far superior crossbow with a thick steel bow and a windlass had been in use in France, Spain and Italy. Some of these later weapons were made so strong in the fifteenth century, that after the invention of the powerful cranequin for bending steel bows, this apparatus was also employed for bending the composite bow - Crossbowmen killing Deer and Wild Boars
From MS. Gaston Phosbus. Fourteenth century - Mounted Crossbowman
A troop of mounted crossbowmen, of special skill and courage, usually formed the bodyguard of the king, and attended him in battle. Mounted crossbowmen were largely employed on the Continent in the fourteenth, and first half of the fifteenth century, and these men were usually allowed one and sometimes even two horses apiece, besides being supplied, when on the march, with carts to carry their crossbows and quarrels - Crossbowmen practising at the target
Their dogs are retrieving the arrows, and were trained to do this without injuring the feathers of the missiles. From a translation into Italian of 'A History of the Peoples of the North,' by Olaus Magnus, Archbishop of Upsala. Printed at Venice, 1565. - Archer and Crossbowman of about 1370
The kneeling figure is fitting his belt-claw to the string of his crossbow, preparatory to bending its bow. From Manuscript No. 2813 in the National Library, Paris, reproduced by J. Quicherat in his ' History of Costume in France,' 1875. - Shooting rabbits with the crossbow
Joannes Stradanus, born at Bruges 1536, died at Florence 1605, a Flemish historical painter who delighted in portraying all kinds of sport, such as shooting, hunting, fishing and coursing, which he did with wonderful skill and in most realistic fashion. This picture is reduced from ' Venationes Ferarum,' a work consisting of 105 large plates of sporting scenes, dated 1578. The hunters carry stonebows, and the rabbits are being driven from their burrows by smoke and fire. Purse nets and stop nets may also be seen in use. - Crossbowmen
The centre figure may be seen bending his crossbow with a windlass, with his foot in the stirrup of the weapon. From Manuscript, Froissart's ' Chronicles. - Different forms of crossbow bolts
I, 2, 3, 4, 5, 6, 7, military bolts ; 6, bolt with tow soaked in oil for firing ships and houses ; 7, bolt for a slur bow ; 8, bolt for killing deer ; 9, 10, bolts for killing large birds ; 11, 12, bolts for killing game birds. The latter had not metal heads, and were blunt, so as not to damage the game. - A store of crossbow bolts, shafts and heads
The crossbowman is aiming at a target to the left of the picture. From a catalogue of the Arsenal of the Emperor Maximilian I. (6. 1459, d. 1519). - Crossbowman approaching game

Of this plate Valturius quaintly writes: ' When everything is cleared for navigation before the charge is made upon the enemy, it is well that those who are about to engage the foe should first practise in port, and grow accustomed to turn the tiller in calm water, to get ready the iron grapples and hooked poles, and sharpen the axes and scythes at their ends. The soldiers should learn to stand firm upon the decks and keep their footing, so that what they learn in sham fight they may not shrink from in real action. - Crossbowman, about 1430
