The two sides involved in World War I were the Allies and the Central Powers. Both sides had basically the same weapons, and once the war got into the Trench Warfare stage it was nearly impossible for either side to win.Trench warfare started in 1914, and continued until the end of the war.
The history of the United States Marine Corps (USMC) begins with the founding of the Continental Marines on 10 November 1775 to conduct ship-to-ship fighting, provide shipboard security and discipline enforcement, and assist in landing forces.
They had delivered a fighting force to the Old World and forced concessions from a foreign ruler. The Marines and the American Navy were celebrated as symbols of the young nationâs military muscle. A little more than 40 years later, the Marines again played a pivotal role in a foreign military campaign. War broke out between the US and Mexico in 1846. By 1847, American forces had seized control of the war, but the nationâs capital, Mexico City, had not been taken.
