The war in the air has been prosecuted with the
utmost vigour during the week. The Royal Flying Corps disturbed the enemy's communications daily and nightly, and fought many duels. Eighty- four enemy machines were destroyed in six days, while twenty- seven of ours failed to return. Our airmen continued their visits to Germany, bombing Zweibrticken last Saturday, Kaiserslautern last Sunday, and Mannheim on Monday, and inflicting serious damage on railways and munition works. All our machines returned safely. On Thursday morning the enemy opened a heavy bom- bardment on the British front from the east of Arras to the south of St. Quentin—a distance of nearly fifty miles. This may or !nay not prove to be the prelude to the long-threatened German offensive.
