On the night of March 22, 1945, the 5th Infantry Division of Patton's Third Army launched assault boats across the Rhine River at Oppenheim, south of Mainz, with no preparatory artillery fire.

Kennedy, the 35th President of the United States, Commander-in-Chief of the armed forces, and a decorated World War II naval veteran, was assassinated while riding in a motorcade through Dealey Plaza in Dallas, Texas. The killing of America's youngest elected president, just thirteen months after the Cuban Missile Crisis brought the world to the brink of nuclear war, sent shockwaves through the military establishment and altered the course of the Cold War, particularly the escalating conflict in Vietnam.

The Hull Note and the Fleet That Sailed for Pearl Harbor
On the same day that Secretary of State Cordell Hull delivered America's final diplomatic demands to Japan, the "Hull Note" requiring complete withdrawal from China and Indochina, the Japanese First Air Fleet of six aircraft carriers under Vice Admiral Chuichi Nagumo secretly departed Hitokappu Bay in the Kuril Islands, sailing toward Pearl Harbor. The two events occurring simultaneously made the Pacific War inevitable: diplomacy's last breath and the strike force's first movement happened on the same November day.

The Sand Creek Massacre
Approximately 675 U.S. volunteer soldiers of the 1st and 3rd Colorado Cavalry under Colonel John Chivington attacked a peaceful encampment of Cheyenne and Arapaho people at Sand Creek in southeastern Colorado Territory.

The massacre, initially celebrated as a victory, was exposed by congressional investigations and became one of the most infamous atrocities in American military history.

Among the dead was Patrick Cleburne, one of the most brilliant division commanders on either side. Franklin effectively destroyed the Army of Tennessee as a fighting force.

Japan's Imperial Conference Authorizes War
In a solemn gathering at the Imperial Palace in Tokyo, Emperor Hirohito's Imperial Conference, the highest decision-making body in Japan, formally authorized war against the United States, Great Britain, and the Netherlands. The decision, made six days before the attack on Pearl Harbor, represented the point of no return: diplomatic negotiations were abandoned, and the massive military operations already in motion were given final imperial sanction. The Pacific War, which would kill millions and reshape the global order, was now inevitable.

Washington's Farewell to His Officers at Fraunces Tavern
General George Washington gathered his remaining officers at Fraunces Tavern in New York City to bid them farewell before resigning his commission and returning to private life. In one of the most emotional scenes of the American Revolution, Washington embraced each officer individually, tears streaming down his face, then walked silently to the waterfront and boarded a barge for Annapolis. His voluntary relinquishment of military power, when he could have become a king, remains one of the most consequential acts in the history of democratic governance.

British Forces Capture Jerusalem from the Ottoman Empire
British and Commonwealth forces under General Edmund Allenby captured Jerusalem from the Ottoman Empire, ending 400 years of Turkish rule over the Holy City. The Ottoman garrison withdrew rather than subject the city to bombardment, and Allenby famously entered on foot through the Jaffa Gate two days later out of respect for the holy sites, a deliberate contrast to the Kaiser's mounted entry in 1898. The fall of Jerusalem was a tremendous morale boost during a year of devastating Allied setbacks on the Western Front.
