This war was one of the greatest known gruesome battles in the world's history, which occurred from 1914 to 1918. From August 14 to the 25th of 1914, the main clashes of the Battle of the Frontiers took place. The complete time covered goes from August 7 to September 13. While the seven Imperial German units moved westwards, from the timetables that historians provide us, it can be shown that the German planned a very methodical attack on France which was known as The Schlieffen Plan. If there were to be an invasion from the Imperial Germany, the commander of France's army organized a defensive plan, known as Plan XVII. This plan was the French army's safety net in order to create an offensive movement on the perimeter of the eastern and the northeast Belgian and French border, which was in the province of Ardennes. On the affirmation of war breaking out between France and Germany, the French military organized an advancement east and north-eastward in order to counter the German threat.
The Battle of the Frontiers had four principal battles in 1914: The Battle of Lorraine - also called Morhange - from August 14 to 25. The Battle of the Ardennes, which took place from the 21 to 23 August. The Battle of Charleroi on 21 to 23 August, and lastly the Battle of the Mons which lasted only for one day, August 23. Germany's military prepared to engage in a somewhat altered rendition of the Schlieffen Plan, which was developed in 1905 by Count Alfred von Schlieffen.
