On 5 January 1916, the Austro-Hungarian Army attacked Serbia's ally Montenegro. The small Montenegrin army offered strong resistance in the Battle of Mojkovac, which greatly helped the withdrawal of the Serbian Army, but soon faced impossible odds and was compelled to surrender on 25 January. The Austro-Hungarians advanced down the coast of the Adriatic Sea into Italian-controlled Albania. By the end of the winter, the small Italian army in Albania had been forced out of nearly the whole country. At this point, with the war in the Balkans almost lost, the British General Staff wanted to withdraw all British troops from Greece, but the French government protested strongly and the troops remained. The Allied armies entrenched around Thessaloniki, which became a huge fortified camp, earning themselves the mocking nickname "the Gardeners of Salonika". The Serbian Army (now under the command of General Petar Bojović), after rest and refit on Corfu, was transported by the French to the Macedonian front.
