When hand-to-hand combat returned to warfare: 30 days at Heartbreak Ridge

The Month-Long Siege of Heartbreak Ridge

They called it Heartbreak Ridge for good reason. In fall 1951, U.S. and French troops faced a month of hell on a seven-mile stretch of Korean hills.

North Korean forces had built a fortress of bunkers just 1,500 yards from Bloody Ridge. The first attacks failed badly.

American tanks finally broke through on October 11, cutting enemy supply lines. French troops then stormed the peak two days later.

The cost was steep: 3,700 Allied casualties against an enemy that lost 25,000 men.

The Korean War Veterans Memorial in Washington tells this grim story through its Wall of Remembrance, where names of the fallen remind us what Heartbreak truly meant.

North Koreans Built a Fortress Just Down the Road

North Korean forces moved back from Bloody Ridge in September 1951 and set up only 1,500 yards away on a seven-mile stretch of hills.

They quickly made these spots even tougher, digging deep trenches and building bunkers that could handle heavy bombing. The main defense points were Hills 851, 894, and 931, all linked by ridgelines.

The Korean People’s Army put their 23rd Regiment from the 13th Division in charge of holding this ground no matter what.

American Generals Badly Misjudged the Enemy’s Strength

General Thomas de Shazo made a big mistake thinking North Korean defenses weren’t very strong. He used just the 23rd Infantry Regiment and the French Battalion instead of bringing in more troops.

Colonel James Adams led the 23rd Regiment’s attack from the east across the Sat’ae-ri Valley. Meanwhile, Colonel Ralph Monclar and his French Battalion took positions on Hill 868, ready to join the fight.

The First Day Turned Into a Bloodbath

On September 13, the 23rd Infantry Regiment charged up the steep, heavily armed slopes while the French Battalion joined the attack on ridge positions.

As soon as American troops moved forward, North Korean defenders fired deadly mortar and machine gun shots that killed soldiers by the dozens.

American units attacked in small groups instead of together, making them easy targets for the well-placed defenders.

Two Weeks of Fighting Chewed Through American Units

The battle quickly became deadly as American commanders sent in units one at a time – first platoons, then companies, then battalions to replace units that got wiped out.

Some groups of 100-200 men completely vanished in the fighting. About 85% of American deaths came from North Korean mortars that hit with deadly aim.

When Americans reached enemy bunkers, they often fought hand-to-hand with bayonets and small shovels.

The Attack Plan Needed a Complete Overhaul

General Robert Young finally stopped what he plainly called the “fiasco” on September 27. By then, the 23rd Regiment had lost over 950 men in just two weeks with almost nothing gained.

American commanders finally realized that sending in troops bit by bit wasn’t working and they needed a totally different plan. They started over and created a new plan focused on cutting off North Korean supply lines.

Operation Touchdown Would Hit From All Sides

Major Thomas Mellon created a new plan in late September that looked much different from the earlier failed tries. This time, all three regiments would attack at once with full artillery support backing them up.

The 72nd Tank Battalion got orders to drive their Sherman tanks up the Mundung-ni Valley to cut the enemy’s supply routes. But first, engineers had to build a road that could handle tanks.

Engineers Worked Under Fire to Build a Tank Road

The 2nd Engineer Combat Battalion led by Colonel Robert Love took on the dangerous job of clearing obstacles in the valley.

They removed mines, filled bomb holes, and broke down six-foot rock barriers that North Korean troops had set with hand grenades. The engineers kept working while enemy snipers and mortar teams shot at them constantly.

By October 10, they finished the road for the tanks.

Tanks Caught Chinese Reinforcements in the Open

More than 30 Sherman tanks from the 72nd Tank Battalion roared across the Mundung-ni Valley on October 11 in a surprise attack.

By chance, they ran straight into the Chinese 610th Regiment moving across open ground to help defend the ridge. The tanks fired their main guns and machine guns, catching the Chinese completely exposed.

The Chinese troops died in huge numbers, and the key supply lines to Heartbreak Ridge were finally cut.

Infantry Fought Bunker by Bunker Up the Ridge

With enemy supply lines cut, American and French forces started the slow, brutal work of clearing the ridge one bunker at a time.

The fighting lasted two more days with soldiers often fighting at arm’s length with knives, bayonets, and shovels. The 23rd Regiment’s 1st Battalion and the French Battalion pushed north, taking very few prisoners.

Most North Korean and Chinese defenders chose to die fighting rather than give up.

French Troops Stormed the Final Peak

At dawn on October 13, Colonel Monclar’s French troops launched a final attack on the peak of Hill 851.

The French Battalion had fought alongside American forces through the entire month-long battle, earning great respect from their allies. Their final push came after 30 straight days of combat in harsh conditions.

After fierce fighting that morning, they took Hill 851 and planted their flag on the top.

The Month-Long Battle Left Thousands Dead

The battle for Heartbreak Ridge finally ended on October 15, 1951, after more than a month of non-stop fighting.

American and French forces suffered over 3,700 casualties, with the 23rd Regiment and French Battalion taking almost half of those losses.

North Korean and Chinese forces lost an estimated 25,000 men killed, wounded or captured.

The battle became a perfect example of the Korean War’s grinding stalemate, where thousands died fighting over the same few hills day after day.
