the Forwarding of Salonique is an offensive carried out by the allied armies installed to Salonique during First World War. It was held 1915 with 1918.

Following the attacks Austro-Allemandes and Bulgarian against the Serbia, the allies installed in Salonique a base of supply and support for the Serb army.

The French troops (under commandemant of the general Maurice Paul Emmanuel Sarrail) unloaded as of on October 5th, 1915, thus violating the neutrality of Greece in the conflict. But they could not prevent the crushing of the Serbe army which took refuge in Thessalonique, where it could be reconstituted thereafter. Thessalonique became thus a city - refuge. Transformed into fortified camp, it accommodated nearly a half-million men: French, British, Serb, Russian who constituted the allied force.

In spite of considerable military manpower, the face of Salonique played only one minor part in this conflict. The allies did not record any victory over the Bulgarian ones, except that of Monastir, city which they took again at Bulgarian the in November 1916. It is only in September 1918 that the French troops (more known under the name of Armée with the East under the orders of Louis Franchet d' Espérey), the English and Serb armies, took again the offensive and could reconquer the Serbia. This date marks the collapse of the Bulgaria.
