The German Army General Von Markens, who defeated the Russians in a terrible way on the Eastern Front, took action again and served as the commander-in-chief of the Balkan Army Group of the Allies, with the 5th and 14th Army of Austro-Hungary, and was commanded by Austro-Hungary infantry general von Kovis; the 12th Army of Germany, commanded by German artillery general von Galvitz; the 1st Army of Bulgaria, commanded by Bulgarian Lieutenant General Bogadijev.

On October 15, 1915, the Serbia-Black coalition forces finally learned what devastating artillery was. The Allied forces concentrated 1,700 heavy artillery and 72 thunderbolters to cover the positions of the Serbia-Black coalition forces. Under two days of artillery bombardment, 90% of the front-line positions of the Serbia-Black army were destroyed, with extremely heavy casualties.

On October 17, the Austro-Hungarian army first crossed the river in the northern suburbs of Belgrade, which had become ruins, and only suffered slight resistance. The German army then crossed the river and advanced rapidly towards the hinterland of Serbia. General Kovis ordered a army to be left to "clean" the city of Belgrade, and the rest of the troops followed the German army to advance towards the hinterland of Serbia.

But in the city of Belgrade, where rubble was covered with almost ruins, the remaining Serbian troops carried out tenacious resistance. These remnants from almost 27 different units spontaneously organized. With the cut off of support, they engaged in a fierce and arduous street-by-street battle with the Austro-Hungarian army. Every street and every ruin had to lay several layers of corpses and dye them with blood to determine their final ownership.

General Kovis, commander of the 5th Austro-Hungarian Army, once asked Marshal Markens, the commander-in-chief of the Army Group, to transfer another army to Belgrade. Markens rejected this request. He was trying his best to capture the Black field troops. The more troops the better, and he did not want to waste too much field infantry resources for a ruined city. However, those heavy artillery units with inconvenient mobility have not crossed the river, and Belgrade is within range.

On the morning of the 19th, the Austro-Hungarians withdrew from the downtown of Belgrade, and then the carpet bombardment began. After 15 hours, when the Austro-Hungarians entered the downtown of Belgrade again, it was already silent.

The Serbia-Black coalition forces flew south in a swarm. Prime Minister Basic’s only hope now is to escape as many troops as possible, and to retain some seeds for Serbia.

The poor roads in the Balkans restricted the speed of the German and Austrian coalition forces. After several troops stretched out like an octopus, they only surrounded about 150,000 Swiss-Black coalition forces, and the remaining 200,000 Swiss-Black coalition forces rushed towards Thessalonika.

The Allies could not withstand the collapse of the southwestern front. An British and French coalition landed in Thessalonik, responded to the Serbia-Black coalition, and stabilized the front.

The front line temporarily saw the British, French, Serbia and Black coalition forces confronting the German and Austrian coalition forces.

The Allied Allied Forces backed by the sea had sufficient maritime supplies, while the German and Austrian coalitions were unable to launch an attack because the logistics and artillery units had not yet arrived.

During the confrontation between the two sides, Serbia Prime Minister Basic took advantage of the extremely weakening of the "black shadow" to launch a harsh purge on the "black shadow", an extremely nationalist secret organization in the Serbian army.

However, with the inauguration of the German-Austrian coalition heavy artillery units, the Bulgarian army also joined the Serbian front after pacifying Macedonia. The allied German-Austrian-Battle coalition had huge firepower and military strength advantages. Markensen began to launch a fierce attack, and the Allied front was shaky.

The Supreme Command of the British and French, who had no intention of fighting with the Allies in the Balkans, decided to withdraw the troops, and the British and French coalition forces evacuated from the fleet to Egypt. However, due to insufficient ships, the Seychelles-Black coalition forces could only retreat from land to Greece. Under the pursuit of the German and Austrian protection forces, the Seychelles-Black army suffered huge casualties again.

In the end, the Serbian-Black coalition was transported to Corfu by British and French fleets with ships vacated in Greece. The Serbian-Black troops who were able to reach Corfu Island. Including the wounded, there are only 150,000 people left. In the Second Battle of Serbia, the Allied Forces cleared the entire Balkan region and achieved the strategic goal of connecting with Turkey, which greatly promoted the battle on the front line of Turkey.

The German and Austrian coalition swept across the Balkans, and the Austro-Hungarian army successively captured Mende Negro and Albania. The Serbian army on Corfu became the best excuse for Austro-Hungary to attack the island. Although Britain and France quickly used ships to withdraw 150,000 Serbian troops on the island, the Austro-Hungarian army still occupied the island.

Now only Thessalonika is left, where about 120,000 Allied Expeditionary Forces gathered here, nominally commanded by French General Morris Salay.

Theoretically speaking, Greece is still a neutral country, but the pro-Alliance Prime Minister Venizelos has always acquiesced to the Allies to support Serbia through Greek territory, using Greek ports and railways to transport supplies for Serbia, and inciting the Allies to send troops to land and occupy Thessalonika.

King Constantine could not tolerate Venizelos' blatant destruction of Greek neutrality. After the German and Austrian coalition forces marched into Serbia, the king announced the removal of Venizelos's post and arrested him and imprisoned.

But it was too late now. As the German and Austrian army began to siege Thessalonika, the Greeks could only watch from the side. Fortunately, Lee Haydn had no intention of invading south.

The Greeks then lost the Macedonian region that they had taken from the Bulgarians three years ago. Lee Haydn did not mean to give it to the Bulgarians. A Macedonian country that was incorporated into the Austro-Hungarian Empire was a good choice, but now is not the time to do this.

Now the Orient Express Road advocated by the German emperor can finally play its role. The Berlin-Baghdad railway connecting West Asia is now unobstructed. Military aid from Germany can be transported to Turkey in large quantities and exchanged for all kinds of food that are urgently needed.

Italy's defeat has now almost controlled the entire European continent, except for France and the Iberian Peninsula, which greatly enhanced the allies' ability to continue war, thus making the prospects of the Allies look bleak.

With the fall of Thessalonika, the most important port on the Aegean Sea, the British fleet now had to withdraw from this area, and the Austro-Hungarian Navy is now in control of the Aegean Sea.

However, the Austro-Hungarian fleet is currently unable to enter the Black Sea. The Turks and British have laid a large number of mines in the Dardanelles. Without eliminating these hidden dangers, the fleet will be unable to pass through at all.

It can take several months to clear mines from the waterway.

With the arrival of winter, the entire front fell silent again.

1915 was a year of great disaster for the Allies. Now there are only three participating countries left in the Allies: Britain, France and Russia. Of course, their allies from faraway areas are not counted. The Russians have been crippled. On the front line of France, the British and French coalition forces huddled in the trenches are like hedgehogs, making it difficult for the Germans to get out of their mouths.

This year, on the Western Front, the total casualties of the British and French forces were 1.57 million, and the German casualties reached 690,000. The battlefield on the Western Front became a huge meat grinder. Germany and France had almost fallen into a state of blood loss due to huge personnel consumption.

The blood of the Germans and French was achieved by the British.
