Apache warriors had never seen howitzers – until they ambushed exhausted Union soldiers in Arizona, 1862

Cochise and Mangas Coloradas’s Apache Pass Ambush

In July 1862, ninety-six Union soldiers trudged through Apache Pass, parched and worn from miles of desert heat.

They had one goal: reach Apache Spring, the only water for miles.

But Cochise and Mangas Coloradas had other plans. From behind stone walls, 500 Apache warriors waited until the soldiers got close, then struck.

The Union troops first fell back, then fought smart. Captain Roberts rolled up two mountain howitzers – weapons the Apache called “wagons that fire.”

As shells rained down on their positions, the Apache fled by nightfall. Soon after, Fort Bowie rose at this strategic spot, changing the Southwest forever.

The ruins still stand at Apache Pass, where water once meant life or death.

California Soldiers Marched 900 Miles to Fight Confederates

In 1862, Colonel James Carleton led 2,500 California Volunteers on a tough 900-mile walk from Fort Yuma toward New Mexico.

They needed to kick out Confederate forces who moved in when Regular Army troops left to fight back east. Carleton’s men took Tucson on May 20, making a small Confederate group run away without a fight.

The men faced the harsh Arizona desert with few water spots, making Apache Pass vital since Apache Spring was one of the only reliable water sources for hundreds of miles.

Captain Roberts Led 96 Exhausted Men Toward Danger

On July 15, Thomas Roberts set out with 96 men from the 1st California Infantry toward Apache Pass. His group included two 12-pounder mountain howitzers under Sergeant James Monihon and 22 cavalry soldiers as guards.

The men needed to set up supplies at San Simon River and check if the main army could use the route. The soldiers were already tired from walking many miles in hot desert with little water.

Roberts split his group at San Pedro River, taking infantry and artillery ahead while Captain Cremony stayed back with supply wagons.

Two Powerful Apache Leaders Joined Forces

Cochise and Mangas Coloradas, the most feared Apache war chiefs, gathered about 500 warriors to defend their land.

They saw Apache Pass as sacred homeland and a key spot they needed to control. The Apache built stone walls on hills looking over Apache Spring and set up strong defense spots.

Their plan was simple: wait for soldiers to enter the pass before attacking when troops were most open to danger. This group was the largest team of Apache warriors against U.S. military forces.

The Deadly Ambush Caught Soldiers Off Guard

At noon on July 15, Roberts’ column walked into Apache Pass, moving about two-thirds through the narrow path toward the spring.

Apache warriors hid behind rocks until Union soldiers came within 30-80 yards.

The ambush started with war cries and heavy gunfire from hidden spots on nearby hills. Union troops ran for cover but found themselves stuck in open ground with no protection.

The soldiers badly needed water but couldn’t move forward under Apache crossfire from higher ground.

Roberts Pulled Back His Men to Regroup

After the intense firefight, Roberts ordered his men to pull back to the mouth of Apache Pass. The Union forces took shelter in ruins of an old Butterfield Overland Mail station for safety.

Roberts got his two mountain howitzers ready for a counterattack against the Apache spots. This was one of the first times the U.S. Army used artillery against Native Americans in Southwest fighting.

The Apache warriors kept their spots in stone walls on hills that gave them control of both sides of the spring.

Howitzers Turned the Tide of Battle

Roberts moved his howitzers forward under heavy fire, though he struggled because his spot was 300-400 feet below the Apache defenses.

The captain ordered the guns moved to better places despite ongoing Apache rifle fire hitting his artillery crews.

Once the howitzers got close enough, they started a steady bombing, sending exploding shells into Apache spots. Apache warriors, who had never seen artillery before, later called the wheeled cannons “wagons.”

The shell blasts among rocks created deadly stone pieces and shock waves the Apache had never felt before.

A Scout’s Desperate Fight Changed History

Union scout John Teal got cut off from his five-man team during a running fight with Apache warriors. His horse got shot, forcing him to hide behind the dead animal while Apache fighters surrounded him.

During this standoff, Teal shot a large Apache warrior from his saddle, not knowing he had just wounded Mangas Coloradas. The chest wound to the war chief caused the Apache attack to slow as Mangas left the battlefield.

Teal stayed put until dark, then snuck past Apache guards carrying his saddle several miles to rejoin the main force.

Union Troops Finally Reached Life-Saving Water

The artillery fire forced Apache warriors to leave their stone walls as darkness fell.

Union troops finally reached Apache Spring and the badly needed water after fighting all day in the desert heat.

Two California soldiers died and three got wounded in the battle, while Apache deaths ranged from 10 to 63 according to different reports.

Roberts let his tired men eat and rest before going back to bring up Captain Cremony’s group. Apache forces moved to nearby hills but stayed in the area.

Apache Warriors Tried Again at Dawn

Apache fighters came back at dawn on July 16, trying to retake the spring and push out the Union forces.

Roberts quickly set up his howitzers again, and the artillery fire scattered the Apache attackers without much of a fight.

The mental impact of the artillery proved key as Apache warriors ran away after the bombing started.

Union forces kept control of the water source, letting the California Column’s main body move through safely. Apache fighting stopped due to the artillery fire and heavy losses from the day before.

Soldiers Found Murdered Travelers Near the Battlefield

The day after the battle ended, Union scouts found nine scalped white civilian bodies on the New Mexico side of Apache Pass.

The victims looked like travelers or settlers who had been ambushed and killed by Apache war parties. This discovery strengthened Colonel Carleton’s belief that a permanent military post was needed to protect the vital water source.

Apache Pass had long been used by Apache warriors to ambush travelers, freight wagons, and mail coaches. The location created a natural chokepoint where small Apache forces could attack much larger enemy groups.

A New Fort Rose from the Battlefield

Colonel Carleton quickly saw the strategic importance of controlling Apache Pass and ordered a fort built.

Fort Bowie was set up within weeks of the battle, with 100 men from the 5th California Infantry stationed there. The new fort controlled the water source and stopped future Apache ambushes of military columns and civilian travelers.

The installation became a key base for future Apache Wars operations and campaigns against Geronimo.

The Battle of Apache Pass directly led to permanent U.S. military presence in the region and began the systematic push to control Apache territory.

Visiting Fort Bowie and Apache Pass, Arizona

Fort Bowie National Historic Site at 3500 Apache Pass Road in Bowie preserves the battlefield where Cochise and Mangas Coloradas ambushed Union soldiers in 1862.

There’s no entrance fee, but you’ll need to hike 1.5 miles to reach the visitor center and fort ruins. The trail passes Apache Spring, old Butterfield Stage Station remains, the fort cemetery, and stone battle positions.
