In this chapter we shall endeavour to gain a superficial view of the general course of events upon the whole front of the Fifth Army upon the fateful March 21. We shall then be in a position to appreciate the situation as it was in the evening and to understand those decisions on the part of General Gough and his subordinates which influenced the subsequent operations. The front of the Fifth Army extended from its junction with the Third Army in the neighbourhood of La Vacquerie to Barisis, a village some miles south of the Oise, the total frontage being nearly forty miles. This was occupied by four corps. The northern was the Seventh, under General Congreve, a well-known soldier, whose V.C. and shattered arm proclaimed his past services to the Empire. This corps covered the southern part of the dangerous Cambrai salient and extended to the region of Ronssoy. From this point to Maissemy the line was held by General Watts with the Nineteenth Corps. Upon his right, extending as far as north of Essigny, {81} was General Maxse with the Eighteenth Corps. From thence to Barisis lay the Third Corps under General Butler. All four were soldiers of wide experience, their leader, General Gough, had never failed in any task to which he had laid his hand, and the troops in the line comprised some of the flower of the British army, so that in spite of all disparity of numbers there was a reasonable hope for success. Arrangements had been made by which the French or British could send lateral help to each other; but it must be admitted that the liaison work proved to be defective, and that the succours were slower in arriving, and less equipped for immediate action, than had been expected.
