Hangang Bridge bombing

On 25 June, North Korea invaded South Korea, sparking the Korean War. Against a lightly armed and poorly equipped South Korean military, the North Korean assault forces and supporting tanks easily overwhelmed their defenses and within two days were positioned extremely close to Seoul.

In the early morning of 27 June, President Syngman Rhee had himself evacuated away from Seoul by his special train with several other South Korean government officials, despite informing his country on the previous day (26 June) of the decision by him and his government cabinet to remain behind in the capital city even with the looming threat of a North Korean attack on it.{{cite news However, the South Korean Army failed to announce the approaching demolition to Seoul residents.{{cite news

On 28 June, at 2:30 am, the demolition charges were detonated without warning. On the bridge were retreating soldiers and policemen crossing the river when it was demolished. ROK Ministry of National Defense confirmed that 77 policemen from Seoul Jongno Police Station died in the blast at that time.

Three American war correspondents – Burton Crane of The New York Times, Frank Gibney of Time magazine and Keyes Beech of the Chicago Daily News – were trying to cross the bridge by jeep. The blast occurred in their faces (only 25 yards away), shattering their windshield. Burton Crane and Keyes Beech reported their experience immediately. When it came to casualties in the articles, they only announced that truckloads of South Korean soldiers were all killed without mentioning anything about civilian casualties.{{cite news |title=Reporter in Korea Has Feeling He saw Start of 3rd World War |url=https://www.newspapers.com/image/140008567|publisher= St. Louis Post-Dispatch|date=28 June 1950 |access-date=18 February 2024}}

It was estimated there were 200–800 killed (mostly soldiers and policemen) but the exact number and identification of victims has not been established yet.

The South Korean Army's Fifth Division was also cut off from its retreat path, leaving it stranded on the north bank of the Han River and at the mercy of the oncoming North Korean forces. At 11:00 am, the North Korean Army then reached the bridge, and shortly after crossing the river, successfully occupied Seoul.

The military engineer responsible for the bridge and carrying out the demolition, Colonel Choi Chang-sik, was court-martialed for misbehavior before the enemy. He was found guilty and sentenced to death. Chang-sik was executed by firing squad on 21 September 1950. In 1964, Choi's wife pleaded his innocence to an appeal tribunal and the court found Choi as not guilty because the demolition order was issued by his superior officers.

On 28 June 2007, the first memorial service was held by a local veterans' peace association.
