First Stages of the last Allied Offensive.

This success at the beginning of the last battle of the war was due partly to the brilliant tactical surprise, partly to the high efficiency of the new Tanks, and also in some degree to the evident deterioration in the quality of the German infantry in that part of the front. The enemy machine-gunners did not display their old tenacity. The Allied casualties were extraordinarily small, one Canadian division, which was in the heart of the battle, losing only 100 men. It was very clear that the fortitude of the German line was ebbing, and this more than any other fact disturbed the minds of its commanders. Ludendorff has recorded in his Memoirs that after the battle of 8th August he realized that Germany was beaten.

The Tanks played a brilliant and dramatic part in the day's success. One Tank captured a village single-handed, and its wary commander solemnly demanded a receipt for the village before he handed it over to the Australians. But the chief performance of the day was that of the "whippet" Tank "Musical Box," commanded by Lieutenant C. B. Arnold, and carrying as crew Gunner Ribbans and Driver Carney. This Tank started off at 4.20 a.m. in company with the others, and when she had advanced the better part of 2 miles discovered herself to be the leading machine, all the others having been ditched. She came under direct shell-fire from a German field battery, and turned off to the left, ran diagonally across the front of the battery at a distance of 600 yards, and fired at it with both her guns. The battery replied with eight rounds, fortunately all misses, and the Tank now managed to get to the battery's rear under cover of a belt of trees. The gunners attempted to get away, but "Musical Box" accounted for them all.

If a Tank can be said to go mad, this Tank now performed that feat. She started off due east straight for Germany, shooting down Germans whenever she saw them. The Australian infantry were following her, and for some time she was also in touch with two British cavalry patrols. Seeing a party of the enemy in a field of corn, she charged down upon them, killing three or four. She found a patrol of our cavalry dismounted and in trouble with some Germans on a railway bridge, so she made for the bridge and dispersed the Germans. She moved still farther east, and approached a small valley marked on Lieutenant Arnold's map as containing German hutments. As she entered the valley the Germans were seen packing their kits and beginning to move, and "Musical Box" opened fire. There was a general flight, but this did not prevent her guns from accounting for a considerable number. She now turned a little to the left across open country, firing at retreating German infantry at ranges of from 200 to 600 yards, and being heavily fired on by rifles and machine-guns in reply. Unfortunately she was carrying petrol tins on her roof, and these were perforated by the hail of bullets, so that the petrol ran all over the cab. The great heat from her engines and guns, which had been in action for nine or ten hours, made it necessary at this point for the crew to breathe through their box-respirators.

It was now about 2 o'clock in the afternoon, and "Musical Box" was still moving east, shooting at anything she could see, from motor transport to marching infantry, and getting heavily peppered in return. At last Lieutenant Arnold was compelled to withdraw the forward gun. The fumes and the heat were stifling, but the crew managed to endure it till suddenly the gallant "Musical Box" was struck by two heavy shells following close one upon the other, and the cab burst into flames. Carney and Ribbans reached the door and collapsed. Lieutenant Arnold was almost overcome, but managed to get the door open and fall out upon the ground. He was then able to drag out the other two men. Burning petrol was running on to the ground where they were lying, and the clothing of all three was on fire. They struggled to get away from the petrol, and while doing so Carney received his death wound. The enemy were now approaching from all quarters, and, having been thoroughly scared, they not unnaturally treated the two survivors somewhat roughly.

Lieutenant Arnold and Gunner Ribbans, badly burned, incredibly dirty, half-suffocated, and fainting with fatigue, were led off into captivity, after having completed such an Odyssey of devastation as perhaps befell no other two men in the war.

CHAPTER XIV.

THE AUSTRALIANS AT MONT ST. QUENTIN.

Close to the spot where the South Africans made their great stand in the retreat of March 1918, it fell to the lot of troops from another of our Dominions to perform an almost miraculous exploit in the advance eastward to victory. By 30th August, as we have seen, the tide had fully turned. All the British armies were pressing back the enemy over the old Somme battlefield, and that enemy was struggling desperately to hold on to key positions long enough to enable him to retire in good order to the Hindenburg Line, where he hoped to stand on the defence over the winter. But these key positions were now being rushed too fast to permit of an orderly retreat, and so the Hindenburg defences proved of no avail, and before the end of October the Germans were a defeated army.

Of all the key positions the strongest was that of Mont St. Quentin, which commanded the old town of Péronne on the north. Péronne, as readers of Sir Walter Scott will remember, was the scene of some of the adventures of Quentin Durward. It had fallen into British hands in March 1917, when the Germans first retired to the Hindenburg Line. It had been lost in the great enemy onslaught of the following March. It was a very strong place, defended on the south and west by the links of the marshy Somme, and on the north by the low ridge called Mont St. Quentin, which provided superb gun positions. The place was held by one of the best of the German Divisions brought up from the reserve, the 2nd Prussian Guards. Their orders were to maintain it at all costs, for unless Mont St. Quentin was held, Péronne would fall, and if Péronne fell it would be a very battered remnant that would struggle back to the main Hindenburg Line.
