move" designed to overextend the Germans. He ordered Haig to prepare for an attack at Aubers Ridge, rather than an attack by Smith-Dorrien at Messines-Wytschaete Ridge, as he had more confidence in both Haig and his troops than he had in Smith-Dorrien. GHQ then learned (16 February) that Joffre wanted de Maud'huy's French Tenth Army to attack at Vimy, with which attack Haig was ordered to co-ordinate his efforts. Joffre wrote a letter of complaint (19 February) that the BEF might not be carrying out Sir John's promise to take over more line; in reply French summoned the liaison officer Victor Huguet to complain of Joffre's claims that the British had demanded French participation in the offensive and that they had more men per mile of trench than the French did (much of the French front, as Sir John pointed out, required smaller garrisons as it was of less tactical importance or rougher terrain). Sir John complained (21 February 1915) that Joffre "treated him like a corporal", although he thought the French "gloriously brave". When he had calmed down he sent Robertson and Wilson to smooth things over with Joffre, writing that Joffre's rude letter had probably been written by "some upstart young French staff officer". Even so, Joffre was angered by French's formal reply (23 February) and thought that he ought to be able to carry out the planned relief as he was receiving the 46th (Territorial) Division. Haig visited de Maud'huy (28 February) and learned that he would be lending only limited artillery support to the offensive. Joffre told GHQ (7 March) that the offensive must be postponed. Millerand wrote to Kitchener to complain, enclosing another letter of complaint from Joffre. Kitchener (3 March) forwarded both letters to Sir John, along with a letter of complaint of his own (which French described as "might be written by an old woman ... silly trash"). Joffre thought French (6 March 1915) a "liar" and "a bad comrade". Neuve Chapelle French genuinely hoped for a breakthrough at Neuve Chapelle (10–12 March 1915) and personally briefed the cavalry commanders Allenby and Rimington beforehand, although, aware of the effect of modern firepower on cavalry, he cautioned Rimington against getting too close to the enemy. He believed that victory would prove to Kitchener that British efforts should be concentrated on the Western Front, and that it would be merely a prelude to a much
