Patton promoted to captain and joins Pershing's staff

In May 1917, amidst the backdrop of World War I, George S. Patton was promoted to the rank of captain on the 15th. Following the United States' entry into the war in April, he joined General John J. Pershing's advance party, which was tasked with preparing for the deployment of American forces to the European theater. Patton was part of a contingent of 180 men who departed for Europe on May 28, 1917. Upon arrival, he was assigned to oversee the training of American troops in Paris until September of that year. His role was crucial in ensuring that the newly formed American Expeditionary Forces (AEF) were adequately prepared for the challenges they would face on the Western Front. After his time in Paris, Patton moved to Chaumont, where he served as a post adjutant, commanding the headquarters company that managed the AEF base. However, Patton found this assignment unsatisfactory and began to explore his interest in armored warfare, particularly tanks, which would later become a significant aspect of his military career. His early experiences during this pivotal time laid the groundwork for his future innovations in tank warfare and leadership in World War II.
