The bulk of the cavalry and field artillery of both divisions, together with the divisional troops, were compelled to set out by march-route from Aldershot for the line of defences. The single and all-sufficient reason of this delay in sending out the cavalry and artillery was owing to the totally inadequate accommodation on the railways for the transport of so many horses and guns. The troop-trains, which were of course, necessary to transport the infantry, were not forthcoming in sufficient numbers, this owing to the fact that at several points the lines to London were still interrupted. The orders to the cavalry who went by march-route were to get up to the line proposed to be taken up by the infantry as quickly as possible, and to operate in front of it to the east and north-east in screening and reconnoitring duties. The temporary deficiency of cavalry, who ought, of course, to have been the first to arrive at the scene, was made good as far as possible by the general employment of hordes of motor-cyclists, who scoured the country in large armed groups, in order to ascertain, if possible, the dispositions of the enemy. This they did, and very soon after their arrival reported the result of their investigations to the general officers commanding the 1st and 2nd Divisions. Meanwhile both cavalry and artillery in great bodies, and strings of motor omnibuses filled with troops, were upon the white, dusty roads passing through Staines to Hounslow and Brentford, thence to London, St. Albans, _en route_ to their respective divisions. Roughly, the distance was over fifty miles, therefore those marching were compelled to halt the night on the way, while those in the motor omnibuses got through to their destination. The sight of British troops hurrying to the front swelled the hearts of the villagers and townsfolk with renewed patriotism, and everywhere, through the blazing, dusty day, the men were offered refreshment by even the poorest and humblest cottagers. In Bagshot, in Staines, and in Hounslow the people went frantic with excitement, as squadron after squadron rapidly passed along, with its guns, waggons, and ambulances rumbling noisily over the stones in the rear. Following these came pontoon troops with their long grey waggons and mysterious-looking bridging apparatus, telegraph troops, balloon sections, supply columns, field bakery, and field hospitals, the last-named packed in waggons marked with the well-known red cross of the Geneva Convention. No sooner was Aldershot denuded of its army corps, however, than battalions began to arrive from Portsmouth on their way north, while troops from the great camp on Salisbury Plain were rapidly being pushed to the front, which, roughly speaking, extended through Hitchin, Royston, to Saffron Walden, across to Braintree, and also the high ground commanding the valley of the Colne to Colchester.
