The German garrison on this front did not occupy any definite trench system, but occupied scattered rifle pits and rifle trenches just large enough to afford shelter for small groups and machine-gun crews. These hornets' nests were dangerous things to tackle, but the Australians had dealt with such conditions before and went about their work in a cool and businesslike manner. With bombs and bayonets the Germans were killed or driven out of their holes, and as they were all picked men selected for their courage and long experience in warfare they made a gallant resistance. The Australian generally fights better when he has a desperate opponent, and the struggle became intense and at close quarters. In the end the men from overseas crushed all opposition, killing over 150 Germans and taking about 200 prisoners. The success of this minor operation was of some importance, as it enabled the Allies to advance their line 500 yards. At this time, in the course of the offensive, the Germans introduced, as a new form of "frightfulness," a sneezing powder, that was fired by high explosive shells. The sneezing powder sifts down through the gas masks and causes sneezing when the wearer is forced to take off his mask and receives the full effect of the lethal gases which the Germans had spread abroad. Preparations were now under way for a new offensive. It was known to the Allies that Ludendorff had already massed 70 divisions and that reenforcements of men and guns were daily brought into the fighting area. The Germans now sought for a basis for a new drive, feeling their way by making thrusts here and there on the Allies' front. On May 8, 1918, they made a drive at the British lines in the battle area north of Kemmel in the Lys salient, penetrating trenches between La Clytie and Voormezeele. About 25,000 German troops took part in this attack. In the night General Haig's men came back in force and drove them out, but the Germans contested the field again and again during the following day. They won a little ground here and there, but were eventually thrown back and the British remained in sole possession of the terrain. North of Albert the Germans captured a small but important strip of trenches on high ground. Their temporary success was dearly won, for they suffered terrible slaughter from the rifle and machine-gun fire which poured into their ranks as they advanced up the slopes. By a brilliant counterassault the Germans were driven out of the position won before they could organize the defenses. East of Bouzincourt, where the British occupied positions on high ground, the enemy followed much the same tactics, but they were unable to gain even temporary foothold in the British defenses. The graycoats advanced, shouting in English "retire," in the hopes of confusing the British. The response of the defenders was such a fierce fire that the Germans acted on their cry and fell back in disorganized masses, leaving hosts of dead on the field.
