“For aged folks on crutches, And women great with child, And mothers sobbing over babes That clung to them and smiled, And sick men borne in litters High on the necks of slaves, And troops of sun-burned husbandmen With reaping-hooks and staves. “And droves of mules and asses Laden with skins of wine, And endless flocks of goats and sheep, And endless herds of kine, And endless trains of waggons That creaked beneath the weight Of corn-sacks and of household goods, Choked every roaring gate. “Now, from the rock Tarpeian, Could the wan burghers spy The line of blazing villages Red in the midnight sky. The Fathers of the City, They sat all night and day, For every hour some horseman came With tidings of dismay.” LORD MACAULAY. I About March 14 the 3rd and 5th Armies were warned by their aerial reconnaissance that a new and ominous concentration was taking place behind the enemy’s lines. These two Armies, to which the 2nd, 3rd, and 4th Tank Brigades were, it will be remembered, attached, held the line which lay between Bullecourt to the north and St. Quentin to the south. Behind them lay the old Somme battlefields, and about them was a dry, rather bare, downland country with few woods and divided up by broad valleys that ran east and west across it. It was a part of the line upon which we had long considered the blow might probably fall. The 3rd and 5th Armies, now on the alert, immediately set about raiding the enemy and, having captured the desired prisoners and examined them, were consistently told the same story. Thursday, March 21, was to be the day of attack. The weather, which had been clear and bright for a week or two, broke on Tuesday, the 19th, and all day it rained heavily. On the night of the 20th a thick mist came up and lay densely over the downs. Such weather conditions only made an attack the more certain, and all along the line Tanks were moved forward into their allotted positions. At two o’clock in the morning of the 21st the British line was warned to expect an attack. The forward zone was already fully manned, but at 4.30 an order was sent out to man the battle zone. Nor was the order premature. The mist still lay heavily over the lines, and under its cover the Germans had secretly pushed up their troops until all along the front between Bullecourt and La Fère, they had massed thirty-seven divisions on a line little more than a mile from our outposts. The drama was about to begin. At a quarter to five every German battery from the Marne to Dunkirk opened fire. Such a bombardment had never been known before, and it reached its zenith on the fronts of the 3rd and 5th Armies.
