Japan had a long period of peace after the battle.

The Battle of Ball's Bluff in Loudoun County, Virginia on October 21, 1861, was one of the early battles of the American Civil War, in which Maj. Gen. George B. McClellan’s Army of the Potomac (Union) suffered a humiliating defeat. The operation was planned as a minor reconnaissance across the Potomac to establish whether the Confederates were occupying Leesburg. A false report of an unguarded Confederate camp encouraged Brig. Gen. Charles Pomeroy Stone to order a raid, which clashed with enemy forces. A prominent US Senator in uniform, Colonel Edward Baker, tried to reinforce the Union troops, but failed to ensure that there were enough boats for the river crossings, which were then delayed.

The Medicine Lodge Treaty is the overall name for three treaties signed near Medicine Lodge, Kansas, between the Federal government of the United States and southern Plains Indian tribes in October 1867, intended to bring peace to the area by relocating the Native Americans to reservations in Indian Territory and away from European-American settlement. The treaty was negotiated after investigation by the Indian Peace Commission, which in its final report in 1868 concluded that the wars had been preventable. They determined that the United States government and its representatives, including the United States Congress, had contributed to the warfare on the Great Plains by failing to fulfill their legal obligations and to treat the Native Americans with honesty. The U.S. government and tribal chiefs met at a place traditional for Native American ceremonies, at their request. The first treaty was signed October 21, 1867, with the Kiowa and Comanche tribes.

All males from the town between the ages of 16 and 60 were assembled by German troops and members of the collaborationist Serbian Volunteer Command (SDK) and Serbian State Guard (SDS), including high school students, and the victims were selected from amongst them. On 29 October 1941, Felix Benzler, the plenipotentiary of the German foreign ministry in Serbia, reported that 2,300 people were executed. Later investigations by the post-war Yugoslavian government came up with between 5,000 and 7,000 people executed, although these figures were never proven reliable.

It was part of Operation Yoav and was conducted at the end of the operation. It was made possible following the opening of a land corridor from the Negev desert to the rest of Israel in the Battles of the Separation Corridor. The capture had both military and political significance. It helped sever the supply route of the Egyptian expeditionary force's eastern wing, and strengthened Israel's claim to the Negev desert.

1956 — Mau Mau rebellion
The Mau Mau rebellion (1952–1960), also known as the Mau Mau uprising or Kenya Emergency, was an armed conflict in the British Colony of Kenya between the Kenya Land and Freedom Army (KLFA) and the British colonial authorities. While the KLFA was primarily composed of Kikuyu, Meru, and Embu fighters, the movement also drew support from units of Kamba and Maasai. Groups such as the Luo and Kalenjin – who had led significant earlier resistance movements against colonial establishment, such as the Nandi Resistance (1890–1906) were largely not part of the KLFA's core structure. Instead, many from these communities served in the King's African Rifles (KAR), the colonial military force through which the British maintained internal security and quelled the uprising. The KLFA fought against the British Army and the local Kenya Regiment, which included European settlers and African loyalists. The capture of Field Marshal Dedan Kimathi on 21 October 1956 signalled the defeat of the Mau Mau, and essentially ended the British military campaign.

The classrooms at Pantglas Junior School were immediately inundated; young children and teachers died from impact or suffocation.
