The Battle of Raymond was fought on May 12, 1863, near Raymond, Mississippi, during the Vicksburg campaign of the American Civil War. Initial Union attempts to capture the strategically important Mississippi River city of Vicksburg failed. Beginning in late April 1863, Union Major General Ulysses S. Grant led another try. After crossing the river into Mississippi and winning the Battle of Port Gibson, Grant began moving east, intending to turn back west and attack Vicksburg. A portion of Grant's army consisting of Major General James B. McPherson's 10,000 to 12,000-man XVII Corps moved northeast towards Raymond. The Confederate commander of Vicksburg, Lieutenant General John C. Pemberton, ordered Brigadier General John Gregg and his 3,000 to 4,000-strong brigade from Jackson to Raymond.

The Battle of Palmito Ranch, also known as the Battle of Palmito Hill, is considered by some criteria the final battle of the American Civil War.

The battle took place more than a month after the surrender of the Army of Northern Virginia under Robert E. Lee to Union forces at Appomattox Court House, which had since been communicated to both commanders at Palmito. However, in early May Confederate General Edmund Kirby Smith had rejected a proposal from Union Major-General John Pope to surrender Confederate forces in the Trans-Mississippi Department on the same terms that General Ulysses S. Grant had given to Robert E. Lee. As such Kirby Smith only officially surrendered all Confederate forces in the Trans-Mississippi Department on June 2, 1865.

During the aftermath of World War II and the Cold War, the Indochina wars were a series of wars which were waged in Indochina from 1945 to 1991, by communist forces against the opponents. The term "Indochina" referred to former French Indochina, which included the current states of Vietnam, Laos, and Cambodia. In current usage, it applies largely to a geographic region, rather than to a political area. The wars included:The First Indochina War began after the end of World War II with the War in southern Vietnam (1945–1946), which acted as the precursor to the First Indochina War. The conflict officially began in 1946 as a battle of independence against colonialist powers and lasted until the French defeat in 1954. After a long campaign of unsuccessful resistance against the French and the Japanese, Viet Minh forces claimed a victory in the August Revolution after Japanese forces surrendered to the Allies on 15 August 1945, leading to the fall of the Empire of Vietnam and Nguyễn dynasty. In the War in southern Vietnam (1945–1946), British forces temporarily occupied the South with the objective of disarming Japanese forces, starting from 13 September 1945, only to restore French colonial control in 1946. Meanwhile, the communist Viet Minh sought to consolidate power by terrorizing and purging rival Vietnamese nationalist groups and Trotskyist activists. Additionally, other recently formed groups in Cambodia and Laos, such as the Khmer Issarak and the Lao Issara, also began their own guerrilla movements, advocating for independence in their respective countries. In the United Nations, and through their alliance with the United Kingdom and the United States, the French demanded return of their former Indochina colony prior to agreeing to participate in the NATO alliance opposing Soviet expansion beyond the countries of the Warsaw Pact in the Cold War. With support from China and the Soviet Union, the communist Viet Minh continued fighting the French Union, including the anti-communist State of Vietnam, ultimately forcing the NATO-backed French out of North Vietnam as a result of the 1954 Geneva Conference. The Second Indochina War was a group of interconnected civil wars in Vietnam, Cambodia, and Laos. Most often, it refers to what is called the Vietnam War in the United States. It began as a conflict between the United States-backed South Vietnamese government and its opponents, both the North Vietnamese-based communist Viet Cong and the People's Army of Vietnam (PAVN), known in the West as the North Vietnamese Army (NVA). The conflict began in 1955 and lasted until 1975 when the North Vietnamese army conquered South Vietnam. The United States, which had supported France and its native vassal during the First Indochina war, backed the Republic of Vietnam government in opposition to the communist Viet Cong and PAVN. The North benefited from military and financial support from China, the Soviet Union, and other members of the communist bloc. Fighting also occurred during this time in Cambodia between the US-backed government, the PAVN, and the communist-backed Khmer Rouge, which also fought alongside deposed King Sihanouk's government in exile and in Laos between the US-backed government, the PAVN, and the communist-backed Pathet Lao. The Third Indochina War was a period of prolonged conflict following the Second Indochina War. The conflict began in 1978 and lasted until the 1991 Paris Peace Agreements on 23 October 1991, in which several wars were fought:The Cambodian–Vietnamese War began when Vietnam invaded Cambodia and deposed the genocidal Khmer Rouge regime. The war lasted from 21 December 1978 to 23 October 1991. Cambodia's constitutional monarchy was then restored in 1993.The Sino-Vietnamese War was a four-week war fought in February–March 1979 between the People's Republic of China and the Socialist Republic of Vietnam. The Chinese launched a punitive expedition in revenge for the Vietnamese invasion of Cambodia, and withdrew a month later to prewar positions. Skirmishes along the border would continue until the two countries normalized relations on 5 November 1991.After the triumph of the Pathet Lao, an anti-communist insurgency in Laos lasted until most Hmong insurgents surrendered in 2007, though some resistance cells remained active for several years after. Thailand, which supported the Lao insurgents, as well as the anti-Vietnamese forces in the Third Indochina War, fought a few skirmishes with Vietnam in 1984, and a short conflict with Laos in 1987.FULRO insurgency in Vietnam – United Front for the Liberation of Oppressed RacesThe Communist Party of Thailand fought an insurgency from 1965 to 1989. They received backing from Laos and Vietnam from 1975 to 1979 but were expelled from their bases and lost most of their supply lines after they sided with the Cambodian-Chinese aligned forces, rather than the pro-Soviet Vietnamese and Laotian regimes.

The train was traveling at 102 miles per hour (164 km/h) in a 50 mph (80 km/h) zone of curved tracks when it derailed.

The WannaCry ransomware attack was a worldwide cyberattack in May 2017 by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the form of bitcoin cryptocurrency. It was propagated using EternalBlue, an exploit developed by the United States National Security Agency (NSA) for Microsoft Windows systems. EternalBlue was stolen and leaked by a group called The Shadow Brokers (TSB) a month prior to the attack. While Microsoft had released patches previously to close the exploit, much of WannaCry's spread was from organizations that had not applied these patches, or were using older Windows systems that were past their end of life. These patches were imperative to cyber security, but many organizations did not apply them, citing a need for 24/7 operation, the risk of formerly working applications breaking because of the changes, lack of personnel or time to install them, or other reasons.
