From 8 to 12 December 1915, an Allied military planning conference took place at GQG with the military representatives of the
Allied powers, France, Britain, Russia, Serbia and Italy, to form a common strategy for 1916 against the Central Powers. The British representatives were the BEF Commander-in-Chief Sir John French and
Chief of the Imperial General Staff Sir
Archibald Murray (just before they were superseded by Douglas Haig and Robertson). General
Carlo Porro (it) represented Italy. Joffre proposed and his Allied counterparts concurred that the offensives of the Allied armies on the Western Front should be delivered simultaneously or close enough so that the Central Powers would be unable to transport reserves from one front to another. The coordinated offensives were planned to commence as soon as possible, with local, limited attacks taking place in between, further to enervate the Central Powers, weather permitting. From 12 to 13 March 1916 another meeting at Chantilly endorsed the plan for synchronised attacks, Russia to begin with an offensive at about 15 May and the rest joining in about two weeks later. Serbian troops had been re-equipped and were to be transferred to Salonika, the Italian army in Albania and the Franco-British in Macedonia would indefinitely maintain the threat of an attack. The delegates also agreed that the blockade on the Central Powers should be made more rigorous. ==Third Chantilly Conference==
