The Confederate Helicopter – A Crazy Idea?

The Confederate Helicopter – A Crazy Idea?

It Looked Good on Paper

General Winfield Scott’s Anaconda Plan of blockading Southern ports was successful by 1862. The Confederacy was having difficulty exporting cotton and importing weapons, putting a strain on its war effort. In Mobile, Alabama an ingenious architectural engineer named William C. Powers had a somewhat crazy idea that might stop the Union ships from blockading Mobile Bay and elsewhere.

Powers wanted to bomb the Union ships in Mobile Bay to oblivion using a steam-powered helicopter. He began his helicopter plan using designs, drawings, and ideas from Leonardo da Vinci and Archimedes. His resulting drawing was of a machine we would consider today to resemble a crude helicopter-like craft.

Powers helicopter design had an engine in the middle, two smokestacks, and two vertical Archimedes’ screws meant to provide lift and get the craft airborne. Another two horizontal Archimedes’ screws, one on each side, would provide the thrust needed to propel the helicopter forward. A rudder for steering and control was at the back of the craft. Two models were made of the helicopter, a small model and a full-sized one.

Powers deserves credit for his helicopter design ingenuity. His helicopter had some advanced technology built into it. For example, it had a lattice construction to provide strength while decreasing overall weight. The lattice construction was innovative and a sound idea. During WWII, the British used lattice construction when they built the Wellington bomber. Powers was cleverly ahead of his time.

Powers’ Confederate helicopter might have looked good on paper and in models, but it was never built. Providing money and resources for the helicopter was a problem for the Confederacy. The contraption also had serious design flaws. An expert at the Aeronautics Department of the National Air and Space Museum in Washington has examined Powers’ helicopter design. He has concluded that the steam engine was a major flaw.

Aeronautical expert Tom Poane of the museum claims that Civil War-times steam engines were impossible to construct light enough, small enough, and powerful enough, for Powers’ helicopter to fly. He also explains that the Archimedes’ screws would not provide enough lift and thrust needed for flight.

 

 

Archimedean Screw

Archimedes’ screws were used in Egypt before the third century BC to move water from a low place up to higher irrigation ditches. They worked well in that capacity, but Archimedes’ screws were not meant to move air. The Archimedes’ screws would probably have been too heavy for a Civil War steam engine’s relatively limited power. Plus, the helicopter would have to carry a heavy bomb or bombs. These bombs would have to be large enough to destroy a ship.

Perhaps Powers’ Confederate helicopter sounds crazy to us today, but the Civil War brought on many inventions and innovations which sounded crazy for the times. These inventions included the telegraph, photography, submarines, ambulances, ironclads, and hot air balloons. All of these successful inventions changed how the Civil War was fought and life after the Civil War.

We know the Confederate helicopter was a failure. It was a dream that never got off the ground. What if Powers’ crazy helicopter idea had actually worked? How would it have influenced the Civil War? We can only imagine and speculate.

Maybe those Yankee blockading ships in Mobile Bay and in other Southern ports would have been bombed to smithereens by a fleet of Confederate helicopters. Then the Confederacy could have shipped cotton out and weapons in. That would be a Civil War game-changer as the Confederacy became stronger. Perhaps the outcome of the Civil War would’ve been different.

Before we judge Powers as being as mad as a March hare, let’s consider two brothers from Ohio who later had a crazy idea about creating a flying machine. Their airplane invention and dreams came true at Kitty Hawk, North Carolina on December 17, 1903, when their plane flew for fifty-nine seconds. Some people thought Wilbur and Orville Wright were crazy.

Even Wilbur Wright had doubts about man ever flying in a heavier-than-air machine:

I confess that in 1901 I said to my brother Orville that man would not fly for fifty years. Two years later we ourselves made flights. This demonstration of my impotence as a prophet gave me such a shock that ever since I have distrusted myself and avoided all predictions.” …Wilbur Wright, 1908.

The Huge Swamp Angel Bombards Charleston

The “Swamp Angel” – A Union 200-Pounder Parrott Gun.

August 22-23, 1863

The “Swamp Angel” was a Union 200-pounder Parrott Gun used on August 22-23, 1863, at Morris Island in Charleston Harbor, South Carolina to shell nearby Charleston.

On April 12, 1861, Fort Sumter was bombarded by Confederate batteries located around Charleston Harbor. Within thirty-four hours the Fort Sumter had surrendered and a long, bloody Civil War was underway. From the moment of its surrender, the recapturing of Fort Sumter became one of the Union’s most important objectives. Nearly four years went by before Union forces were successful at retaking Fort Sumter.

By the summer 1863, the Confederate held Fort Sumter had been bombarded by Federal artillery for two years, but the fort still stood and guarded Charleston. At the entrance to Charleston Harbor is Morris Island and Union General Quincy A. Gillmore and his troops were stationed there. Gillmore wanted to construct an artillery battery on Morris Island so he could directly bombard Charleston and force the city to surrender. Gillmore’s plan would bypass troublesome Fort Sumter and other forts in the Charleston Harbor. A big gun with the range to bombard Charleston would allow Gillmore to force the rebel stronghold of Charleston to surrender. General Gillmore needed the Swamp Angel.

The Swamp Angel was huge. It was cast of iron at the West Point Foundry in New York and it weighed 16,700 pounds. The Swamp Angel’s barrel bore was 8-inches and it had an 11-foot bore depth. Even the construction of the battery and parapet needed for the Swamp Angel was impressive. Merely getting this giant gun into place on the swampy, mushy, ground of Morris Island (with mud sometimes twenty-feet deep) in Charleston Harbor was a challenging engineering job. Construction of the battery and parapet began on August 2, and it included:

  • 13,000 sandbags weighing greater than 800 tons total
  • 123 pine timbers, 45-55 feet in length and 15-18 inches in diameter
  • 5,000 feet of 1-inch thick board
  • 9,500 feet of 3-inch thick planking
  • The spikes, nails, and iron required to hold it all together weighed 1,200 pounds
  • 75 fathoms (450 feet) of rope, 3 inches thick

The Swamp Angel used a 17-pound powder charge to fire a 200-pound projectile 7,900 yards into the heart of Charleston. To add to the threat of the Swamp Angel, the projectiles could be filled with an incendiary fluid called “Greek Fire” that would set Charleston ablaze. On August 17 the Swamp Angel arrived at Morris Island. An awesome weapon of war was about to go to work.

A Huge Monster Cannon

Gillmore sent a message on August 21, to General P. G. T. Beauregard demanding the evacuation of Confederate posts on Morris Island and Fort Sumter, or else shelling of Charleston would start. The Yankees had sighted the Swamp Angel in on the steeple of St. Michael’s Church. Beauregard gave no reply to Gillmore’s demands.

At 1:30 A.M. on August 22, the Swamp Angel belched and roared its first shot at Charleston. Bells, whistles, and alarms from Charleston could soon be heard on Morris Island. Before daylight arrived, fifteen more shots rained down on Charleston from the Swamp Angel. Twelve of these shots filled with Greek Fire.

Charleston was receiving the wrath of the Union in the form of horrible huge shells filled with fire, shot from a huge monster cannon 7,900 yards away. On August 23, the Swamp Angel belched out more shells into Charleston. It looked like the Confederacy would have to surrender Charleston as the Swamp Angel rained its hellish fiery shells on the city.

When the Swamp Angel fired its thirty-sixth shell on August 23, it did something cast-iron Parrott guns were known for, despite their distinctive wrought iron reinforcing bands positioned around their breeches. On its thirty-sixth firing that day the Swamp Angel’s breech blew out and the gun’s barrel flew on top of the sandbag parapet. The great Swamp Angel was dead.

Although it had suffered some damage and a few fires were set by the Swamp Angel, Charleston was now safe. No further huge guns like the Swamp Angel were placed on the Union’s Morris Island battery.

With its blown breech the Swamp Angel’s military career was over. The great gun now was to be sold as scrap iron and physically forever lost to history. However, new life came to the great Swamp Angel. The good citizens of Trenton, New Jersey bought the Swamp Angel and made it into a monument.

If you visit Trenton today, you will find the Swamp Angel at Cadwalader Park. Even if it could still fire and despite all its monstrous might, the Civil War Swamp Angel’s Greek Fire projectiles could not reach Charleston, South Carolina from Trenton, New Jersey. The people of Charleston may rest easy. The Swamp Angel is no longer a threat to them.
