The cavalry dismounted for trench warfare.

General French was short of men and munitions and wished to avoid another offensive until the spring of 1916. But the French were eager to attack in Champagne and the British government felt it had to support its allies. The cavalry was mounted in order to exploit gaps and breakthroughs, but although the 20th Hussars were in the saddle almost continuously, no gaps appeared in their area. Both the 10th and 20th Hussars were involved in the Battle of Loos from 25th September to 8th October 1915, which caused huge casualties and achieved nothing. General French was relieved as Commander-in-Chief by Sir Douglas Haig.
