In little over three weeks of intensive fighting, which not only witnessed the first British use of poison gas, but also the debut of New Army divisions filled with citizen volunteers, British forces at Loos managed to drive up to two miles into the German positions. However, they were unable to capitalise on their initial gains. After suffering nearly 60,000 casualties (three times the number suffered by their opponents) and being driven from the German lines in disorder, bitter recrimination followed. Nick Lloyd presents a reassessment of the Battle of Loos, arguing that it was vital to the development of new strategies and tactics. He places it within its political and strategic context, as well as discusses command and control and the tactical realities of war on the Western Front during 1915.
