The Second Army has been called the Cinderella of our forces. Not only was it holding a long line lightly, and with few reserves, but the main flow of ammunition and material passed it by and went down to the Somme, where the British were creeping forward in desperate fighting to Bapaume. There were weeks in August and September when the allowance of shells dropped to two and even one round per 18-pounder a day, with heavier calibres proportionately rationed.[26] The Germans were in this respect similarly situated. Their ammunition also was wanted on the Somme to put down those eternal barrages with which they opposed our assaults. When the Division first arrived in Flanders the artillery shell-fire was very light indeed. That of the trench mortars did a good deal to replace it. The Germans had concentrated on these weapons as their chief means of offence, and, possessing the advantage of the ground, they used them cleverly and with great effect. With that curious regularity that appeared to form part of the German mentality their bombardments generally took place almost precisely at 3-30 p.m. They were particularly severe in the neighbourhood of the Spanbroek salient.[27] "In this sector," writes a machine-gun officer, "I have seen five or six large 'minnies' in the air at one time--really fearsome things. You could see the fuses of the bombs alight in the air and follow their flight most of the way, only to lose it when straight overhead; and then there was nothing to do but wonder where it would fall!" These long aerial torpedoes exploded with shattering effect and made huge craters. It is useless to disguise the fact that, during the first few weeks of the Division's acquaintance with these trenches, the enemy had an ascendancy in trench-mortar warfare. That ascendancy had to be fought down. In the first place the German mortars, or rather their emplacements, were carefully marked down from observations taken in the line, and by the study of aeroplane photographs. Maps were then issued by the staff, upon which each active emplacement was shown by name. The names began with the letter of the map square; all in the "S" squares with S, and in the "U" squares with U. The names chosen were generally feminine--doubtless without ironic intention. A certain number of the emplacements were allotted to each howitzer battery of the Divisional Artillery, and also to such 6-inch howitzer batteries of the Corps Heavy Artillery as were available. When the mortar opened fire, all that was necessary was for the words "Susie active," or "Ursula active," to be wired back to the batteries. Susie, or Ursula, as the case might be, was instantly engaged, while any machine-guns that could be brought to bear upon her neighbourhood also took a hand in the game. By this means it was generally found possible to silence any individual mortar in about a quarter of an hour at most, and to prevent it from getting the exact range, and
