Beginning in 1950, American military advisors arrived in what was then French Indochina. U.S. involvement escalated in the early 1960s, with troop levels tripling in 1961 and again in 1962. U.S. involvement escalated further following the 1964 Gulf of Tonkin incident, in which a U.S. destroyer clashed with North Vietnamese fast attack craft, which was followed by the Gulf of Tonkin Resolution, which gave the U.S. president authorization to increase U.S. military presence. Regular U.S. combat units were deployed beginning in 1965. Operations crossed international borders: bordering areas of Laos and Cambodia were heavily bombed by U.S. forces as American involvement in the war peaked in 1968, the same year that the communist side launched the Tet Offensive. The Tet Offensive failed in its goal of overthrowing the South Vietnamese government, but became the turning point in the war, as it persuaded a large segment of the U.S. population that its government's claims of progress toward winning the war were illusory despite many years of massive U.S. military aid to South Vietnam. Gradual withdrawal of U.S. ground forces began as part of "Vietnamization", which aimed to end American involvement in the war while transferring the task of fighting the Communists to the South Vietnamese themselves. Despite the Paris Peace Accord, which was signed by all parties in January 1973, the fighting continued. In the U.S. and the Western world, a large anti-Vietnam War movement developed as part of a larger counterculture. The war changed the dynamics between the Eastern and Western Blocs, and altered North–South relations. https://en.wikipedia.org/wiki/Vietnam_War Direct U.S. military involvement ended on 15 August 1973. The capture of Saigon by the North Vietnamese Army in April 1975 marked the end of the war, and North and South Vietnam were reunified the following year. The war exacted a huge human cost in terms of fatalities (see Vietnam War casualties). Estimates of the number of Vietnamese soldiers and civilians killed vary from 800,000 to 3.1 million. Some 200,000–300,000 Cambodians, 20,000–200,000 Laotians, and 58,220 U.S. service members also died in the conflict, with a further 1,626 missing in action.

The New York World-Telegram, later known as the New York World-Telegram and The Sun, was a New York City newspaper from 1931 to 1967. The Library of Congress collection includes about 1 million photographs that the New York World-Telegram & Sun Newspaper assembled mostly 1890 and 1967, the year in which the newspaper closed. This newspaper photo morgue is typical of the files that newspapers maintain of images that either were published or were believed to have some future publication potential. Such files were periodically "weeded" by newspaper staff members. Much of the photography used by newspapers is "quick copy," and many images have been cropped, retouched, or highlighted for publication. Some images were taken by the newspaper's staff photographers while others came from wire press services, studios, or amateur photographers.
