Cpl. Harlon Block, USMC
Weslaco, Hidalgo County, Texas
Marker Inscription
During World War II, U.S. forces captured the small yet strategic Japanese-held Pacific Island of Iwo Jima. On Feb. 23, 1945, during combat, marine Harlon Block aided in laying telephone wire up an inert volcano. At the summit, Block and five others improvised a flagpole, attaching a flag visible to those on the island and outlying ships. In doing so, Block and his fellow servicemen became the subject of one of the most recognized photographic images of World War II, the U.S. flag raising on Mt. Suribachi. On Mar. 1, 1945, his squad leader was killed. Block took command, but was tragically killed hours later. His remains were repatriated in 1949 to his hometown of Weslaco and in 1995 to the Iwo Jima monument in Harlingen. 175 Years of Texas Independence * 1836 - 2011

The Story
In February 1945, U.S. Marines fought to seize the small but strategic Pacific island of Iwo Jima, and Weslaco's own Corporal Harlon Block was among the six men who raised the American flag atop Mount Suribachi—an act frozen into one of the most famous photographs of World War II. Days later, after his squad leader was killed, Block took command but was himself killed within hours. His remains came home to Weslaco in 1949 and were later moved to the Iwo Jima monument in Harlingen.
Why it matters
It personalizes an iconic national image, reminding visitors that the flag-raisers were real young men—many of whom, like Block, did not survive the battle they came to symbolize.
The story behind this marker
AI contextThe era
By the winter of 1945, the Second World War in the Pacific had become a brutal march from one island to the next, each one closer to the Japanese home islands. American forces had learned that seizing these specks of volcanic rock came at a terrible price, and Iwo Jima—barely eight square miles of ash and stone—was among the most costly of all. Its value was measured in geography: airfields within reach of the Japanese mainland, and a place for damaged bombers to land on the long flights home.
The men who fought there came from every corner of the country, and many from the small towns of the Rio Grande Valley. Weslaco, in the citrus and vegetable country of deep South Texas, was one of those towns—a farming community far from the ocean, whose sons nonetheless found themselves on a beach of black sand thousands of miles away.
The home front in 1945 followed the war through newsreels, radio bulletins, and the photographs that ran in every newspaper. It was into that hungry national attention that a single image from this island would land, and it would carry the name of a young man from Weslaco with it.
People & events
Harlon Block was one of the Marines who fought his way up the island's dominant height, an extinct volcano that loomed over the landing beaches. In the course of that fighting he helped carry telephone wire toward the summit—the unglamorous, dangerous work of keeping men in contact under fire. At the top, he and five others raised an American flag on an improvised pole, high enough to be seen by the troops still struggling below and by the ships standing offshore.
That moment, caught by a photographer, became one of the most reproduced images of the entire war—a cluster of straining figures hoisting the Stars and Stripes against the sky. It came to stand for grit, unity, and sacrifice. But the men in it were not symbols. They were young servicemen still in the middle of a battle that was far from won.
Only days later, the fighting claimed Block's squad leader. He stepped up to take command, as trained and expected—and within hours he too was killed. He was a very young man, and his war ended there on the island. His remains came home to Weslaco in 1949, and decades later, in 1995, were moved to rest at the Iwo Jima monument in nearby Harlingen.
Its place in the American story
The flag-raising on that volcanic summit became something rare in American life: an image nearly everyone recognizes, reproduced on posters, stamps, and eventually one of the nation's most famous war memorials. It helped rally a country in the war's final, exhausting stretch and has stood ever since for the courage of ordinary service members.
What this marker insists upon is the human truth beneath the icon. The photograph shows anonymous, straining bodies; the memorial names one of them and tells you he did not come home. The gap between the timeless image and the young man killed within days of it is exactly where the meaning lives.
It also reminds visitors that the story of the Pacific war was written in part by small American towns. A farming community in the Rio Grande Valley sent one of its own to that island, and his name is now permanently tied to an image the whole nation knows.
If you visit
Standing at this memorial in Weslaco, remember that you are far from any ocean, in the flat citrus country of South Texas. That distance is part of the point—the young man honored here traveled a very long way to a place that would make his image famous and cost him his life.
Take a moment to separate the icon from the person. Most visitors arrive knowing the photograph; fewer know that one of the men in it was a local son who was killed only days later. Let the marker close that gap for you.
The memorial pairs naturally with a wider swing through the Valley's World War II remembrance, including the Iwo Jima monument in Harlingen where his remains were later moved. Together they turn an abstract national image into a story rooted in this particular stretch of Texas.

First United Methodist Church of Harlingen
Harlingen, TX
Thirty-one charter members founded Harlingen's Methodist congregation in 1910, at first sharing a frame sanctuary and served by a circuit-riding preacher who walked between towns. With land offered by city founder Lon C. Hill, they built Harlingen's first brick church by Easter 1911 and grew alongside the booming Rio Grande Valley city. The congregation weathered the 1933 Labor Day hurricane as a refuge, sent thirteen members to die in World War II, and helped plant a family of new churches, several serving the area's Spanish-speaking community.
Harlingen Army Airfield and Harlingen Air Force Base
Harlingen, TX
As World War II approached, Harlingen offered the Army 960 acres of its flat coastal plain — useless for artillery but ideal for aircraft — and in August 1941 the Harlingen Army Gunnery School took its first students. At its peak the base trained up to 9,000 airmen, among them Women Airforce Service Pilots, before closing in 1946. Reactivated during the Korean War as Harlingen Air Force Base, it trained more than 13,000 navigators until its 1962 closure dealt the local economy a heavy blow; its grounds now serve an airport, museums, and schools.
Moore Field
Alton, TX
Financed by the neighboring cities of Edinburg, McAllen, and Mission, Moore Field opened in 1941 as a U.S. aviation training base, named for Lt. Frank M. Moore, a pilot killed in World War I. It trained airmen throughout World War II before closing in 1945, was reactivated during the Korean War, and since 1960 has housed research offices of the U.S. Department of Agriculture. Its runways trace the long shadow of three American conflicts across a single Rio Grande Valley site.
Skaggs House
Weslaco, TX
In the 1920s the Rio Grande Valley was booming as irrigation turned raw brushland into profitable citrus groves, and Weslaco rose almost overnight as a planned railroad town. Bankers and citrus growers C. Lester and Florence Richardson Skaggs bought fifteen acres here in 1924 and, in 1927, had prolific local architect R. Newell Waters design them a Spanish Colonial Revival home amid their orchard. The house, its native landscape, and adjoining grove survived in the family until 1992 and became an early preservation cause.
