South Field was a World War II airfield on Iwo Jima in the Volcano Islands, located in the Central Pacific.
 The Volcano Islands are part of Japan.
 The airfield was located on the southern corner of Iwo Jima located on the Motoyama plateau, to the north of Mount Suribachi.
 South Field was significant to the overall Battle of Iwo Jima.
USS "Iwo Jima" (LPH-2) was the lead ship of her class and type—the first ship to be designed and built from the keel up as an amphibious assault ship.
 She carried helicopters and a detachment of embarked Marines for use in the Navy's "vertical envelopment" concept of amphibious operations.
 "Iwo Jima" was the second of three ships of the United States Navy to be named for the Battle of Iwo Jima, although the first to be completed and see service (the first was cancelled during construction).
To the Shores of Iwo Jima is a 1945 Kodachrome color short war film produced by the United States Navy and United States Marine Corps.
 It documents the Battle of Iwo Jima, and was the first time that American audiences saw in color the footage of the famous flag raising on Iwo Jima.
The US National Iwo Jima Memorial is located on Ella Grasso Boulevard, near the New Britain/Newington town line in Connecticut.
 It was erected by the Iwo Jima Survivors Association, Inc. of Newington, Connecticut.
 It was dedicated on February 23, 1995 on the 50th anniversary of the historic flag raising on Iwo Jima.
 It is dedicated to the memory of the 6,821 US servicemen who gave their lives at Iwo Jima.
 Inscribed on the base are the names of the 100 men from Connecticut who gave their lives in the battle.
Iwo To (硫黄島 , Iō-tō , "sulfur island") , known in English as Iwo Jima (    ), is an island of the Japanese Volcano Islands chain south of the Ogasawara Islands and together with them forms the Ogasawara Archipelago also known as the Bonin Islands.
 The island of 21 km (8 square miles) is 1200 km south of mainland Tokyo and is administered as part of Ogasawara, one of the eight villages of Tokyo inhabited only by Japan Self-Defense Forces and used by the U.S. Navy for carrier practice.
 It was the setting of the February–March 1945 Battle of Iwo Jima involving the United States and a small number of elements of the British Pacific Fleet versus the Empire of Japan during World War II.
 The island grew in recognition outside Japan when the photograph "Raising the Flag on Iwo Jima" was taken on Mount Suribachi, the highest point at 160 metres (528 feet), during the battle by Associated Press photographer Joe Rosenthal.
 The U.S. occupied Iwo Jima until 1968 when it was returned to Japan.
Letters from Iwo Jima (硫黄島からの手紙 , Iōjima Kara no Tegami ) is a 2006 Japanese-American war film directed and co-produced by Clint Eastwood, starring Ken Watanabe and Kazunari Ninomiya.
 The film portrays the Battle of Iwo Jima from the perspective of the Japanese soldiers and is a companion piece to Eastwood's "Flags of Our Fathers", which depicts the same battle from the American viewpoint; the two films were shot back to back.
 "Letters from Iwo Jima" is almost entirely in Japanese, although it was produced by American companies DreamWorks, Malpaso Productions, and Amblin Entertainment.
 After "Flags of Our Fathers" underperformed at the box office, DreamWorks swapped the United States distribution rights to Warner Bros., who had the international rights.
The Battle of Shiloh, also known as the Battle of Pittsburg Landing, was a major battle in the Western Theater of the American Civil War, fought April 6–7, 1862, in southwestern Tennessee.
 A Union force known as the Army of the Tennessee under Major General Ulysses S. Grant had moved via the Tennessee River deep into Tennessee and was encamped principally at Pittsburg Landing, Tennessee on the west bank of that river, where the Confederate Army of Mississippi, under General Albert Sidney Johnston and second-in-command P. G. T. Beauregard, launched a surprise attack on Grant's army from its base in Corinth, Mississippi.
 Johnston was mortally wounded during the fighting; Beauregard, who thus succeeded to command of the army, decided against pressing the attack late in the evening.
 Overnight Grant was reinforced by one of his own divisions stationed further north and was joined by three divisions from another Union army under Maj. Gen. Don Carlos Buell.
 This allowed them to launch an unexpected counterattack the next morning which completely reversed the Confederate gains of the previous day.
Shadow of Suribachi: Raising The Flags on Iwo Jima (1995) is a book released during the 50th anniversary of the flag-raising(s) atop Mount Suribachi on Iwo Jima during World War II which was written by Parker Bishop Albee, Jr. and Keller Cushing Freeman.
 The book mainly examines the controversy over the identification of the flag-raiser who was positioned at the base of the flagpole in Joe Rosenthal's "Raising the Flag on Iwo Jima" photograph of the second flag-raising on February 23, 1945.
The Battle of Iwo Jima (19 February – 26 March 1945) was a major battle in which the United States Marine Corps landed on and eventually captured the island of Iwo Jima from the Imperial Japanese Army during World War II.
 The American invasion, designated Operation Detachment, had the goal of capturing the entire island, including the three Japanese-controlled airfields (including the South Field and the Central Field), to provide a staging area for attacks on the Japanese main islands.
 This five-week battle comprised some of the fiercest and bloodiest fighting of the Pacific War of World War II.
Iwo Jima is a turn-based strategy video game developed and published by Personal Software Services for the Commodore 64 and ZX Spectrum in 1986.

 The game is set during the Battle of Iwo Jima in the Pacific Ocean theatre of World War II and revolves around the United States Marine Corps' objective to secure the island of Iwo Jima from the Imperial Japanese Army.
