The British front was now in the icy grip of winter. Snow-drifts made the roads impassable for motor cars. The Germans, however, were not deterred by unfavorable weather conditions from making sporadic raids on British positions. On January 5, 1918, they had some success at Bullecourt, where they captured a British advance post--a dearly bought operation that cost them a heavy toll in casualties. In the afternoon the British came back in force, and, after a tense, close struggle, drove out the Germans and reoccupied the position. On the French front, where a blizzard had been raging and the heaviest snowstorm in years made military operations on any large scale impossible, the Germans continued to be active, and the French were kept busy defending their costly won positions. On January 8, 1918, French troops carried out an extensive and successful raid which was intrusted to foreign legionaries and sharpshooters. The attack was delivered along a front of a mile and to a depth of half a mile in front of Flirey and westward toward St. Mihiel. The French completely cleaned out the German defenses, capturing 178 men and officers and numbers of machine guns and trench mortars. The Germans were so completely taken by surprise that their artillery did not get into action until the French had finished the job. The attack was carried out with such dispatch and in so thorough a manner that the French suffered not more than a dozen casualties, while the German dead lay thick about the field and the snow was streaked with ominous stains. On the same date (January 8) the spell of silence which had brooded for some days on the British front was broken by a hostile attack made by the Germans east of Bullecourt. In the early dawn the British lines were bombarded with high explosives and gas, and about 6.35 three parties of Bavarian troops, who had been lying concealed during the night in no-man's-land, made a quick rush for the British defenses. The front line attacked had been weakened by the recent withdrawal of troops, as an enemy attack was not expected in a sector considered "quiet." Two of the parties of Bavarians carried flame throwers of the most approved type, which darted a jet of fire thirty feet, and literally wiped out with a touch a man's life. This engine of destruction had a terrifying effect on troops who saw it in operation for the first time, but the British soldiers defending the trenches at Bullecourt were seasoned fighters and well acquainted with every type of German frightfulness.
