On August 30, the whole Army having crossed the Oise, the bridges over that river were destroyed, an operation which was performed under a heavy shell-fire, and cost the lives of several sapper officers and men. No words can exaggerate what the Army owed to Wilson's sappers of the 56th and 57th Field Companies and 3rd Signal Company, as also to Tulloch's, of the 17th and 59th Companies and 5th Signal Company, whose work was incessant, fearless, and splendid. The Army continued to fall back on the line of the Aisne, the general direction being almost east and west through Crépy-en-Valois. The aeroplanes, which had conducted a fine service during the whole of the operations, reported that the enemy was still coming rapidly on, and streaming southwards in the Compiégne direction. That they were in touch was shown in dramatic fashion upon the early morning of September 1. The epic in question deserves to be told somewhat fully, as being one of those incidents which are mere details in the history of a campaign, and yet may live as permanent inspirations in the life of an army. [Sidenote: Battery L.] The 1st Cavalry Brigade, greatly exhausted after screening the retreat so long, was encamped near Nery, {128} to the south of Compiégne, the bivouac being a somewhat extended one. Two units were close to each other and to the brigade headquarters of General Briggs. These were the hard-worked 2nd Dragoon Guards (the Bays) and L Battery of Horse Artillery. _Réveillé_ was at four o'clock, and shortly after that hour both troopers and gunners were busy in leading their horses to water. It was a misty morning, and, peering through the haze, an officer perceived that from the top of a low hill about seven hundred yards away three mounted men were looking down upon them. They were the observation officers of three four-gun German batteries. Before the British could realise the situation the guns dashed up and came into action with shrapnel at point-blank range. The whole twelve poured their fire into the disordered bivouac before them. The slaughter and confusion were horrible. Numbers of the horses and men were killed or wounded, and three of the guns were dismounted. It was a most complete surprise, and promised to be an absolute disaster. A body of German cavalry had escorted the guns, and their rifles added to the volume of fire. ------------------------------------------------------------------- {129} [Illustration: "L" Battery Action, Sept. 1st, 1914] -------------------------------------------------------------------
