The Battle of the Trench (Ghazwat al-Khandaq) also known as the Battle of the Confederates (Ghazwat al-Ahzab), was a 30-day-long siege of Yathrib (now Medina) by Arab and Jewish tribes. The strength of the confederate armies is estimated around 10,000 men with six hundred horses and some camels, while the Medinan defenders numbered 3,000. The largely outnumbered defenders of Medina, mainly Muslims led by Islamic prophet Muhammad, dug a trench on the suggestion of Salman Farsi, which together with Medina's natural fortifications, rendered the confederate cavalry (consisting of horses and camels) useless, locking the two sides in a stalemate. Hoping to make several attacks at once, the confederates persuaded the Muslim-allied Medinan Jews, Banu Qurayza, to attack the city from the south. However, Muhammad's diplomacy derailed the negotiations, and broke up the confederacy against him. The well-organised defenders, the sinking of confederate morale, and poor weather conditions caused the siege to end in a fiasco. The siege was a "battle of wits", in which the Muslims tactically overcame their opponents while suffering very few casualties. Efforts to defeat the Muslims failed, and Islam became influential in the region. As a consequence, the Muslim army besieged the area of the Banu Qurayza tribe, leading to their surrender and enslavement or execution. The defeat caused the Meccans to lose their trade and much of their prestige.

The Chauchat was the standard light machine gun or "machine rifle" of the French Army during World War I (1914–18). Its official designation was "Fusil Mitrailleur Modele 1915 CSRG" ("Machine Rifle Model 1915 CSRG"). Beginning in June 1916, it was placed into regular service with French infantry, where the troops called it the FM Chauchat, after Colonel Louis Chauchat, the main contributor to its design. The Chauchat in 8mm Lebel was also extensively used in 1917–18 by the American Expeditionary Forces (A.E.F), where it was officially designated as the "Automatic Rifle, Model 1915 (Chauchat)". A total of 262,000 Chauchats were manufactured between December 1915 and November 1918, including 244,000 chambered for the 8mm Lebel service cartridge, making it the most widely manufactured automatic weapon of World War I. The armies of eight other nations – Belgium, Finland, Greece, Italy, Poland, Romania, Russia, and Serbia – also used the Chauchat machine rifle in fairly large numbers during and after World War I. The Chauchat was one of the first light, automatic rifle-caliber weapons designed to be carried and fired by a single operator and an assistant, without a heavy tripod or a team of gunners. It set a precedent for several subsequent 20th-century firearm projects, being a portable, yet full-power automatic weapon built inexpensively and in very large numbers. The Chauchat combined a pistol grip, an in-line stock, a detachable magazine, and a selective fire capability in a compact package of manageable weight (20 pounds) for a single soldier. Furthermore, it could be routinely fired from the hip and while walking (marching fire). The muddy trenches of northern France exposed a number of weaknesses in the Chauchat's design. Construction had been simplified to facilitate mass production, resulting in low quality of many metal parts. The magazines in particular were the cause of about 75% of the stoppages or cessations of fire; they were made of thin metal and open on one side, allowing for the entry of mud and dust. The weapon also ceased to function when overheated, the barrel sleeve remaining in the retracted position until the gun had cooled off. Consequently, in September 1918, barely two months before the Armistice of November 11, the A.E.F. in France had already initiated the process of replacing the Chauchat with the M1918 Browning Automatic Rifle. Shortly after World War I, the French army replaced the Chauchat with the new gas-operated Mle 1924 light machine gun. It was mass manufactured during World War I by two reconverted civilian plants: "Gladiator" and "Sidarme". Besides the 8mm Lebel version, the Chauchat machine rifle was also manufactured in U.S..30-06 Springfield and in 7.65×53mm Argentine Mauser caliber to arm the American Expeditionary Forces (A.E.F.) and the Belgian Army, respectively. The Belgian military did not experience difficulties with their Chauchats in 7.65mm Mauser and kept them in service into the early 1930s. Conversely, the Chauchat version in U.S..30-06 made by "Gladiator" for the A.E.F., the Model 1918, proved to be fundamentally defective and had to be withdrawn from service. The Chauchat is the only full-automatic weapon actuated by long recoil, a Browning-designed system already applied in 1906 to the Remington Model 8 semi-automatic rifle: extraction and ejection of the empties takes place when the barrel returns forward, while the bolt is retained in the rear position. The failure of its limited version in U.S. 30-06 (the Mle 1918) have led some modern experts to assess it as the "worst machine gun" ever fielded in the history of warfare. However the weapon did remain in active service for over two years during the First World War, was the most widely issued fully automatic light machine gun of that conflict and remained in service after the war ended with several armies.
Chemical warfare (CW) involves using the toxic properties of chemical substances as weapons.

The Eastern Front or Eastern Theater of World War I (Восточный фронт, Vostochnıy front, sometimes called the Second Fatherland War or Second Patriotic War (Вторая Отечественная война, Vtoraya Otechestvennaya voyna) in Russian sources) was a theatre of operations that encompassed at its greatest extent the entire frontier between the Russian Empire and Romania on one side and the Austro-Hungarian Empire, Bulgaria, the Ottoman Empire and the German Empire on the other. It stretched from the Baltic Sea in the north to the Black Sea in the south, included most of Eastern Europe and stretched deep into Central Europe as well. The term contrasts with "Western Front", which was being fought in Belgium and France. During 1910, Russian General Yuri Danilov developed "Plan 19" under which four armies would invade East Prussia. This plan was criticised as Austria-Hungary could be a greater threat than the German Empire. So instead of four armies invading East Prussia, the Russians planned to send two armies to East Prussia, and two Armies to defend against Austro-Hungarian forces invading from Galicia. In the opening months of the war, the Imperial Russian Army attempted an invasion of eastern Prussia in the northwestern theater, only to be beaten back by the Germans after some initial success. At the same time, in the south, they successfully invaded Galicia, defeating the Austro-Hungarian forces there. In Russian Poland, the Germans failed to take Warsaw. But by 1915, the German and Austro-Hungarian armies were on the advance, dealing the Russians heavy casualties in Galicia and in Poland, forcing it to retreat. Grand Duke Nicholas was sacked from his position as the commander-in-chief and replaced by the Tsar himself. Several offensives against the Germans in 1916 failed, including Lake Naroch Offensive and the Baranovichi Offensive. However, General Aleksei Brusilov oversaw a highly successful operation against Austria-Hungary that became known as the Brusilov Offensive, which saw the Russian Army make large gains. The Kingdom of Romania entered the war in August 1916. The Entente promised the region of Transylvania (which was part of Austria-Hungary) in return for Romanian support. The Romanian Army invaded Transylvania and had initial successes, but was forced to stop and was pushed back by the Germans and Austro-Hungarians when Bulgaria attacked them in the south. Meanwhile, a revolution occurred in Russia in February 1917 (one of the several causes being the hardships of the war). Tsar Nicholas II was forced to abdicate and a Russian Provisional Government was founded, with Georgy Lvov as its first leader, who was eventually replaced by Alexander Kerensky. The newly formed Russian Republic continued to fight the war alongside Romania and the rest of the Entente until it was overthrown by the Bolsheviks in October 1917. Kerensky oversaw the July Offensive, which was largely a failure and caused a collapse in the Russian Army. The new government established by the Bolsheviks signed the Treaty of Brest-Litovsk with the Central Powers, taking it out of the war and making large territorial concessions. Romania was also forced to surrender and signed a similar treaty, though both of the treaties were nullified with the surrender of the Central Powers in November 1918.
