1. Assassination of Archduke Franz Ferdinand Link to article- http://www.eyewitnesstohistory.com/duke.htm This article explains the event that was one of the factors that contributed to the start of World War 1. Two bullets were fired on Sarajevo street which shaped the world that we live in today. The victims, Archduke Franz Ferdinand - heir to the throne of the Austro-Hungarian Empire, and his wife Sophie, were in the Bosnian city in conjunction with Austrian troop exercises nearby. The couple was returning from an official visit to City Hall. The assassin, 19-year-old Gavrilo Princip burned with the fire of Slavic nationalism. He envisioned the death of the Archduke as the key that would unlock the shackles binding his people to the Austro-Hungarian Empire. This event triggered World War 1 by involving many different allies to the original countries involved which was Austria-Hungary who had their Archduke murdered. 2. The Sinking of the Lusitania Link to article- http://www.eyewitnesstohistory.com/lusitania.htm The German submarine U-20 had entered the Irish Sea on May 5 and now, the morning of May 7, the submarine claimed its third victim. The U-20 had only three torpedoes left in its arsenal and was low on fuel. As a result, Captain Walter Schwieger, the ship's commander, decided to steer for the open waters of the Atlantic and home. He was unaware that his greatest prize was steaming straight for him and that his actions that day would ultimately bring America into the war. The Lusitania was what was sank, a US ship that left from New York that was headed to the city of Liverpool. The two ships converged at about 2 pm. After stalking his prey for an hour, Captain Schwieger unleashed one torpedo that hit its target amidships. The initial explosion was followed quickly by a second, more powerful, detonation. Within 20 minutes the great liner had slipped under the water, taking 1,198 victims with her. Among the dead were 138 Americans. 3. Gas Attack, 1916 Link to article- http://www.eyewitnesstohistory.com/gas.htm The First World War accelerated the development of new technologies designed to improve the ability to kill an enemy: the machine gun, the tank, the airplane, the zeppelin, and gas to name a few. Among these, gas was probably the crudest, certainly the most capricious - a change in wind direction could spell disaster. Initially, gas cylinders were simply placed along the front lines facing the enemy trenches. Once the wind was deemed favorable, the cylinders were opened and the gas floated with the breeze, carrying death to the enemy. Also later in the war gas was packed into artillery shells and was delivered beyond enemy lines. 4. Armistice, 1918 Link to article- http://www.eyewitnesstohistory.com/armistice.htm This article explains the armistice or the end of world war 1. The final Allied push towards the German border began on October 17, 1918. As the British, French and American armies advanced, the alliance between the Central Powers began to collapse. Turkey signed an armistice at the end of October, Austria-Hungary followed on November 3. Germany began to crumble from within. Faced with the prospect of returning to sea, the sailors of the High Seas Fleet stationed at Kiel mutinied on October 29. Within a few days, the entire city was in their control and the revolution spread throughout the country. On November 9 the Kaiser abdicated; slipping across the border into the Netherlands and exile. A German Republic was declared and peace feelers extended to the Allies. At 5 AM on the morning of November 11 an armistice was signed in a railroad car parked in a French forest near the front lines. This armistice ended one of the most brutal and bloodiest wars of all time, World war 1. Photos from World War 1 1. American Troops using Acoustic Locator Link to photo- https://www.theatlantic.com/photo/2014/04/world-war-i-in-photos-technology/507305/ They were mounted on a wheeled platform. The large horns amplified distant sounds, monitored through headphones worn by a crew member, who could direct the platform to move and pinpoint distant enemy aircraft. Development of passive acoustic location accelerated during World War I, later surpassed by the development of radar in the 1940s. This photo shows the acoustic locator being transported/used by American troops while it was on wheels. 2. Allies Advance on Bapaume.

Two tanks are moving towards the left, followed by troops. In the foreground some soldiers are sitting and standing at the roadside. One of them appears to be having a drink. Beside the men is what appears to be a rough wooden cross with an Australian or New Zealand service hat on it. In the background other troops are advancing, moving field guns and mortars. 3. German Infantrymen in trench. Link to photo- https://www.theatlantic.com/photo/2014/04/world-war-i-in-photos-technology/507305/ German infantrymen from Infanterie-Regiment Vogel von Falkenstein Nr.56 adopt a fighting pose in a communication trench somewhere on the the Western Front. Both soldiers are wearing gas masks and Stahlhelm helmets, with brow plate attachments called stirnpanzers. The stirnpanzer was a heavy steel plate used for additional protection for snipers and raiding parties in the trenches, where popping your head above ground for a look could be lethal move. 4. German Troops Load Gas Projectors Link to photo- https://www.theatlantic.com/photo/2014/04/world-war-i-in-photos-technology/507305/ German troops load gas projectors. Attempting to exploit a loophole in international laws against the uses of gas in warfare, some German officials noted that only gas projectiles appeared to be specifically banned, and that no prohibition could be found against simply releasing deadly chemical weapons and allowing the wind to carry it to the enemy.
