it launched against Germany the chivalry of the world; it created for use against Germany the chivalry of the air; and it left Germany unhonoured in her ultimate downfall. The German plan of campaign, it was rightly believed, was a swift invasion and disablement of France, to be followed by more prolonged operations against Russia. By this plan the German army was to reach Paris on the fortieth day after mobilization. There was no promise that Great Britain would help France, but the attitude of Germany had long been so threatening that the General Staffs of the two countries had taken counsel with each other concerning the best manner of employing the British forces in the event of common resistance to German aggression. It had been provisionally agreed that the British army should be concentrated on the left flank of the French army, in the area between Avesnes and Le Cateau, but this agreement was based on the assumption that the two armies would be mobilized simultaneously. When the principal British Ministers and the leading members of the naval and military staffs assembled at Downing street on the 5th and 6th of August, we were already behindhand, and the whole question of the employment and disposition of the expeditionary force had to be reopened. It was expected by some soldiers and some civilians that the little British army would be landed at a point on the coast of France or Belgium whence it could strike at the flank of the German invaders. The strategic advantages of that idea had to yield to the enormous importance of giving moral and material support to our Allies by fighting at their side; moreover, there could be no assurance that the coast of Belgium would not fall into the hands of the Germans at a very early stage in the campaign. Accordingly, it was agreed to ship our army to France, and to leave the manner of its employment to be settled in concert with the French. The original British Expeditionary Force, under the command of Field-Marshal Sir John French, began to embark on the 9th of August; by the 20th its concentration in a pear-shaped area between Maubeuge and Le Cateau was complete. It consisted of the First Army Corps, under Lieutenant-General Sir Douglas Haig; the Second Army Corps, under Lieutenant-General Sir James Grierson, who died soon after landing in France and was succeeded by General Sir Horace Smith-Dorrien; and the Cavalry Division, under Major-General E. H. H. Allenby. The Germans made no attempt to interfere with the transport of the expeditionary force from England to France. They had many other things to think of, and there is evidence to show that they viewed with satisfaction the placing of that admirable little force in a situation where they hoped that they could cut it off and annihilate it. That they were disappointed in this hope was due not a little to the activity and efficiency of the newest arm, numbering about a thousand, all told, the Royal Flying Corps.
