The European Front Soviet troops continued their push on Serbia, capturing Nish in early February. The Soviet 5th Army from Greece met with the Romanian First and the Bulgarian Second at Nish in late February. The huge armies were ready to push on Belgrade. By March, the Soivet armies were around Belgrade, ready for the order to march into the Serbian capital. Petr I of Serbia fled to Vienna. Finally, in June 1919, Belgrade fell. The Soviet armies continued across the border into Austria-Hungary, destroying towns on their way to Vienna. The Austro-Hungarian High Command decided to retreat toward the Adriatic Coast. The Soviet forces continued into Budapest, which was captured in August. Meanwhile, the Austro-Hungarian Army had completed their retreat into the mountains. With it, the Austrians took all the food stocks from Hungary and Austria and destroyed all strategic installations. The Soviet troops began starving and were unable to cross the Danube to Budapest. Lacking naval power, the Soviet army was stuck in Budapest.
The Arabian Front The British Foreign Office in Cairo had been neglected since a long time, and the armed strength was, minimal. As a result, the Bedouin tribes fighting in the DRA Army had been able to capture the Sinai and the Suez Canal very early in the war. By August, fresh British troops arrived in Alexandria to strengthen the colonial army. Forming a line of defense along the Nile, the British troops were able to push back the DRA troops, and causing the Bedouin army a severe defeat. With this defeat, the various tribes deserted the army and left the DRA Army stripped of 90% of its troops.
The Asian Front The Japanese army in Taiwan invaded French Indochina, with support from Thai soldiers. The Japanese army met heavy resistance in Tonkin, suffering numerous blows on its invasion force. However, helped by anti-French Communist troops, the Japanese army captured the capital, Hanoi in March, and Hue in June. Meanwhile, Thai troops entered Laos and Cambodia, crushing minor French resistance. In Paris, Napoleon IV decided to give up Indochina and surrendered the colony to the Japanese in August. The Japanese and Thai army, joined by various “Free Vietnam” groups marched south on British Malaya, almost unopposed. Kuala Lumpur fell in September, Singapore in October, Sarawak, and Sabah in November. The Japanese army had captured most of South East Asia, with the exception of neutral Dutch East Indies.
