The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event in the Texas Revolution. Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna launched an assault on the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas, USA). All but two of the Texian defenders were killed. Santa Anna's perceived cruelty during the battle inspired many Texians—both Texas settlers and adventurers from the United States—to join the Texian Army. Buoyed by a desire for revenge, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the revolution.

Several months previously, Texians had driven all Mexican troops out of Mexican Texas. Approximately 100 Texians were then garrisoned at the Alamo. The Texian force grew slightly with the arrival of reinforcements led by eventual Alamo co-commanders James Bowie and William B. Travis. On February 23, approximately 1,500 Mexican troops marched into San Antonio de Béxar as the first step in a campaign to re-take Texas. For the next 12 days the two armies engaged in several skirmishes with minimal casualties. Aware that his garrison could not withstand an attack by such a large force, Travis wrote multiple letters pleading for more men and supplies, but fewer than 100 reinforcements arrived.

Marion Mitchell Morrison (born Marion Robert Morrison; May 26, 1907 – June 11, 1979), better known by his stage name John Wayne, was an American film actor, director and producer. An Academy Award-winner, Wayne was among the top box office draws for three decades, and was named the all-time top money-making star. An enduring American icon, he epitomized rugged masculinity and is famous for his demeanor, including his distinctive calm voice, walk, and height.

Wayne was born in Winterset, Iowa but his family relocated to the greater Los Angeles area when he was four years old. He found work at local film studios when he lost his football scholarship to USC as a result of a bodysurfing accident. Initially working for the Fox Film Corporation, he mostly appeared in small bit parts. His acting breakthrough came in 1939 with John Ford's Stagecoach, making him an instant star. Wayne would go on to star in 142 pictures, primarily typecast in Western films.

Among his best known films are The Quiet Man (1952), which follows him as an Irish-American boxer and his love affair with a fiery spinster played by Maureen O'Hara; The Searchers (1956), in which he plays a Civil War veteran who seeks out his abducted niece; Rio Bravo (1959), playing a Sheriff with Dean Martin; True Grit (1969), playing a humorous U.S. Marshal who sets out to avenge a man's death in the role that won Wayne an Academy Award; and The Shootist (1976), his final screen performance in which he plays an aging gunslinger battling cancer.

Martin David Robinson (September 26, 1925 – December 8, 1982), known professionally as Marty Robbins, was an American singer, songwriter, and multi-instrumentalist. One of the most popular and successful country and Western singers of his era, for most of his nearly four-decade career, Robbins was rarely far from the country music charts, and several of his songs also became pop hits.

Robbins was born in Glendale, a suburb of Phoenix, in Maricopa County, Arizona. He was reared in a difficult family situation. His father took odd jobs to support the family of ten children. His father's drinking led to divorce in 1937. Among his warmer memories of his childhood, Robbins recalled having listened to stories of the American West told by his maternal grandfather, Texas Bob Heckle. Robbins left the troubled home at the age of 17 to serve in the United States Navy as an LCT coxswain during World War II. He was stationed in the Solomon Islands in the Pacific. To pass the time during the war, he learned to play the guitar, started writing songs, and came to love Hawaiian music.

Dimitri Zinovievich Tiomkin (May 10, 1894 – November 11, 1979) was a Russian-born Hollywood film score composer and conductor. He is considered "one of the giants of Hollywood movie music." Musically trained in Russia, he is best known for his westerns, "where his expansive, muscular style had its greatest impact." Tiomkin received 22 Academy Award nominations and won four Oscars.

Dimitri Tiomkin (Ukrainian: Дмитро Зиновійович Тьомкін, Dmytro Zynoviyovych Tiomkin, Russian: Дмитрий Зиновьевич Тёмкин, Dmitrij Zinov'evič Tjomkin, sometimes transliterated as Dmitri Tiomkin) was born in Kremenchuk, Ukraine, then part of the Russian Empire.

His family was of Jewish descent, with his father a "distinguished pathologist" and associate of Professor Paul Ehrlich, the inventor and Nobel laureate noted for discovering a cure for syphilis and for his research in autoimmunity, later becoming chemotherapy. His mother was a musician who began teaching the young Tiomkin piano at an early age. Her hope was to have her son become a professional pianist, according to Tiomkin biographer, Christopher Palmer. Tiomkin described his mother as being "small, blonde, merry and vivacious."
