1862: the year Fort Pulaski proved brick forts were obsolete

Colonel Olmstead’s Surrender That Ended Masonry Fortification Era

In 1862, young Colonel Charles Olmstead stood firm at Fort Pulaski with 385 men and brick walls eleven feet thick.

“I am here to defend the fort, not to surrender it,” he told Union forces.

Yet within just 30 hours, new rifled cannons tore huge holes in the fort’s walls. Then came the worst moment – a shell hit the powder magazine holding 20 tons of black powder.

It filled with smoke but didn’t blow up. Olmstead knew the next hit could kill everyone, so he gave up the fight.

His tough choice that day changed war forever, proving brick forts were no match for modern guns. The battle scars at Fort Pulaski National Monument still tell this story today.

Robert E. Lee Started Building a "Fortress of Brick" in 1829

Work began in 1829 on Cockspur Island under Major Samuel Babcock.

Robert E. Lee checked the marshy ground and built a wooden foundation with drains to keep the fort from sinking.

The fort followed “Third System” plans to protect Savannah’s port. Workers used about 25 million bricks to make walls 11 feet thick that seemed unbreakable.

The big project took 18 years and cost nearly $1 million before workers finished it in 1847.

Georgia Grabbed the Fort Before Lincoln Could React

On January 3, 1861, Georgia troops took over Fort Pulaski before federal soldiers arrived. The only caretaker gave up the fort with its rusty guns and few supplies.

The place was a mess with unlivable rooms, an overgrown yard, and a mud-filled moat. About 125 enslaved workers spent months fixing the fort.

Georgia left the Union just 13 days later on January 16, 1861.

A 25-Year-Old Colonel Took the Fort’s Reins

Major Charles Hart Olmstead became commander in October 1861 and soon became a colonel.

The young Savannah native and military school graduate added firepower with 48 guns, including 12-inch mortars and English rifles.

His Confederate troops included 385 men in five infantry companies. The steamboat Ida made daily trips bringing supplies, gunpowder, and bullets to the remote fort.

The Great Robert E. Lee Gave His Blessing

General Robert E. Lee came back to check the fort he helped build 30 years earlier in November 1861.

After walking around with Olmstead, Lee told him, “They will make it pretty warm for you here with shells, but they cannot break your walls at that distance.”

Lee thought Tybee Island sat too far away for good cannon fire. Confederate leaders believed the brick walls made the fort as strong as mountains.

Union Forces Cut Off the Fort From Help

Union troops took nearby Port Royal, South Carolina in November 1861. By December, Federal forces moved onto empty Tybee Island without fighting.

Captain Quincy Gillmore started building cannon spots on Tybee in February 1862. Union soldiers cut the telegraph line and blocked Tybee Creek, leaving the fort alone.

Confederate supplies couldn’t get through after February 1862.

New Weapons Changed the Rules of War

Gillmore began setting up 36 big guns in March 1862. These new guns could hit targets from 4-5 miles away, while old cannons only reached half a mile.

Union crews built their gun spots at night using cover to hide from Confederate lookouts. The new shells were made to crack brick walls rather than just dent them.

Workers finished by early April despite some Confederate return fire.

Union Forces’s Wilson Demanded Surrender

On April 10, 1862, Union Lieutenant Wilson brought a surrender demand to Olmstead. General Hunter wanted “immediate surrender and restoration of Fort Pulaski.”

Olmstead used his 30 minutes to gather his men and ready the defenses. The young colonel sent back his answer: “I am here to defend the fort, not to surrender it.”

Both sides got ready for a battle to test if new weapons could beat old forts.

Modern Cannons Punched Through Impenetrable Walls

Union guns started firing at 8:10 a.m., aiming at the fort’s southeast corner. Confederate gunners shot back with good aim but slowly stopped as their spots got hit.

By noon, shells had made 47 marks on the southeast wall as bricks started breaking apart. The first day ended with the fort looking okay from far away but badly damaged inside.

Two big Union cannons jumped off their stands from firing so hard.

Brick Walls Crumbled Against Rifled Artillery

On April 11, the second day of shelling opened two 30-foot holes in the southeast wall. Shells now flew completely through the fort toward the gunpowder storage.

Confederate guns were knocked out one by one. Rifled shells sent shots across the inside of the fort straight toward the powder room.

Despite more than 5,000 shells hitting the fort, three Confederate soldiers got badly hurt.

A Near Miss Almost Blew Everyone Sky-High

At 1:00 p.m., a shell blew up inside the northwest powder room holding 20 tons of gunpowder. The room filled with light and smoke but somehow didn’t explode.

Olmstead knew the next shell could destroy the entire fort and kill all 385 men inside. The Confederate commander faced a tough choice between honor and his men’s lives.

He later said, “It’s not right putting the troops at risk of our main magazine blowing up.”

Olmstead’s Surrender Haunted Him for Decades

At 2:30 p.m. on April 11, Olmstead raised a white flag and surrendered Fort Pulaski.

The decision troubled the colonel for the rest of his life as he questioned whether he made the right choice. The battle resulted in just one Union and three Confederate casualties, yet it changed warfare forever.

The surrender closed Savannah’s port to Confederate shipping and proved that masonry forts couldn’t stand up to modern weapons.

The 30-hour bombardment completely changed military engineering and coastal defense strategy.
