During the German offensive of March-July, 1918, "even two or three well-trained cavalry divisions might have driven a wedge between the French and British Armies. Their presence could not have failed to have added greatly to the difficulties of our task" (Sir D. Haig's Dispatches). During the _Battle of Cambrai_ (November 20, 1917) a squadron of the Fort Garry Horse crossed the Scheldt Canal, and after capturing a German battery and dispersing a large body of infantry, maintained itself by rifle fire in a sunken road until nightfall, when it withdrew to the British lines with its prisoners. During the _Battle of Amiens_ (August 8-18, 1918) the cavalry were concentrated behind the battle front by a series of night marches, and on the first day of the battle they advanced 23 miles from their position of assembly. Throughout the battle they rendered most gallant and valuable service. During the Second _Battle of Le Cateau_ (October 6-12, 1918) cavalry were instrumental in harassing the enemy in his retreat and preventing him from completing the destruction of the railway, and when the infantry were held up by heavy machine-gun fire from Cattigny Wood and Clary "a dashing charge by the Fort Garry Horse gained a footing in Cattigny Wood and assisted our infantry to press forward. Further east, Dragoon Guards and Canadian Cavalry were instrumental in the capture of Hennechy, Reumont, and Troisvilles" (Sir D. Haig's Dispatches). In the early stages of the campaign in _North Russia_ (August-September, 1918) a handful of cavalry on either bank of the North Dwina River could have kept the Bolshevik forces constantly on the run, and could have prevented the successive reorganisation of their demoralised forces, which the slower progress of the pursuing infantry was unable to accomplish. A few squadrons of cavalry could have dispersed the whole { 67} Bolshevik force in the Archangel Province. Tanks are usefully employed in the pursuit, as artillery, the only effective enemy of the tank, is unlikely to remain in action with the rearward troops of a disorganised enemy; and a new terror has been added to the pursuit by the advent of self-propelled, man-carrying Aircraft, armed with machine guns and bombs, and possibly even with light quick-firing artillery. During the final stages of the victorious _Allied Advance_ in November, 1918, the retreating German Armies were continuously harassed from the air. "Throughout the day (November 5, 1918) the roads, packed with the enemy's troops and transport, afforded excellent targets to our airmen, who took full advantage of their opportunities, despite the unfavourable weather. Over 30 guns, which bombs and machine-gun fire from the air had forced the enemy to abandon, were captured by a battalion of the 25th Division in the field near Le Presau" (Sir D. Haig's Dispatches).
