Monitor vs Virginia

USS Monitor
Yesterday the Virginia struck the Northern fleet, sinking two of the strongest ships, and it appeared there was nothing preventing it from destroying the entire fleet and sailing up to the Northern ports. But that was not too be. When the Virginia sailed out 150 years ago today to finish off the Federal fleet, they met a new opponent. During the night, the Monitor had arrived from the North. It didn't look like much, and at first the Confederates thought it was just machinery being moved on a raft, but soon they discovered how wrong they were. Although it only had two cannon, it had a rotating turret and was much more maneuverable. The ships began circling each other and firing, and it was found that both of their armor was very strong.

But both ships had their disadvantages. The Virginia had not brought solid shot, only exploding shells. While shells were good for wooden ships, they did not do much against the Monitor's iron sides. The Monitor's pilot house had been put in a bad position. The captain was severely wounded when a shell exploded outside the opening while he was looking out.

The battle continued for several hours, with no serious damage being done on either side. The Virginia's ram was broken, but they tried to get alongside to board, hoping their larger crew would carry the day, but the more maneuverable did not let the ships come together. At one point the Virginia ran aground, but they were able to get it afloat again. Although neither ship was being destroyed, it was a hard fight for the men inside their iron sides. The blood ran from their ears from the pounding of the shots on the side and the noise of their cannon firing, and inside the Monitor the boltheads were knocked loose and flew around inside.

At one point Lt. Jones of the Virginia came down to the guns and saw that they were not firing. "Why are not you firing, Mr. Eggleston?" he asked. The officer questioned replied, "Why, our powder is very precious, and after two hours' incessant firing I find I can do here about as much damage by snapping my thumb at here very two minutes and a half." A Federal officer wrote this:
"I triced up the port, ran out the gun, and taking deliberate aim, pulled the lockstring. The Merrimac was quick to reply, returning a rattling broadside (for she had ten guns to our two), and the battle fairly began. The turret and other parts of the ship were heavily struck, but the shots did not penetrate; the tower was intact, and it continued to revolve. A look of confidence passed over the men's faces, and we believed the Merrimac would not repeat the work she had accomplished the day before. The fight continued with the exchange of broadsides as fast as the guns could be served and at very short range, the distance between the vessels frequently being not more than a few yards. Worden skillfully man|uvred his quick-turning vessel, trying to find some vulnerable point in his adversary. Once he made a dash at her stern, hoping to disable her screw, which he thinks he missed by not more than two feet. Our shots ripped the iron of the Merrimac, while the reverberation of her shots against the tower caused anything but a pleasant sensation."
Finally, after fighting for six hours, both ships realized that it was useless to continue. They both ended the drawn battle, and went back claiming victory. The Virginia hoped to get solid shot and try again the next day, but the expected rematch never occured. The Monitor never accepted a challenge of single-handed combat, and soon the superior resources of the North built more ironclads to contain the Virginia.

While the battle was a draw, it is clear who were the strategic winners. The Monitor had put a stop to the feared Virginia. No more did the North fear the Virginia sailing to Washington and pounding the government into submission. Never again would a Confederate ironclad have the same chance as the Virginia to completely change the course of the war. Although most of the Union navy was obsolete for naval combat, they could bring their superior resources to bear and build ironclads that could fight anything the South could hope to build.

The Virginia Attacks the Northern Fleet

CSS Virginia
At the same time as the Battle of Elkhorns tavern was being fought, another equally important naval battle was being fought off Hampton Roads, Virginia. The Confederates had raised the USS Merrimack, and had converted her from a normal sailing ship to a new ironclad called the CSS Virginia. She was ready to attack the blockading squadron off Virginia in early March. As she moved down the river, the engineers were still working on getting her ready for battle. She had strong armor, but she was slow. She carried several guns, and another important tactic would be ramming in the sides of the wooden ships. As she moved forward 150 years ago today, she was accompanied by what was called a Mosquito Fleet, small gunboats carrying one or two cannon. They were not strong enough to stand up to the Federal ships, and did not play an important role in the battle.
Ramming the Cumberland

The Union blockading squadron at Hampton Roads consisted of the Congress, Cumberland, St. Lawrence, Roanoke and Minnesota along with some smaller boats. Although they were all wooden, they were some of the most powerful ships the United States had. When the Union fleet saw the Virginia approaching with her sister ships, they went out to meet her. The St. Lawrence and Roanoke ran aground before reaching the Virginia. The Virginia picked out the Cumberland and charged in an effort to ram. The Cumberland opened fire on the Virginia, but the shots just bounced off the ironclad's armor. Getting in range, the Virginia sped up to ram the Cumberland. Ashton Ramsey, an officer on the Virginia, remembered the experience:
"There was an ominous pause, then a crash, shaking us all off our feet. The engines labored. The vessel was shaken in every fiber. Our bow was visibly depressed. We seemed to be bearing down with a weight on our prow. Thud, thud, thud, came the rain of shot on our shield from the double-decked battery of the Congress. There was a terrible crash in the fire-room. For a moment we thought one of the boilers had burst. No, it was the explosion of a shell in our stack. Was any one hit? No, thank God! The firemen had been warned to keep away from the up-take, so the fragments of shell fell harmlessly on the iron floor-plates. We had rushed on the doomed ship, relentless as fate, crashing through her barricade of heavy spars and torpedo fenders, striking her below her starboard fore-chains, and crushing far into her. For a moment the whole weight of her hung on our prow and threatened to carry us down with her, the return wave of the collision curling up into our bow port. The Cumberland began to sink slowly, bow first, but continued to fight desperately for the forty minutes that elapsed after her doom was sealed, while we were engaged with both the Cumberland and the Congress, being right between them. We had left our cast-iron beak in the side of the Cumberland. Like the wasp, we could sting but once, leaving it in the wound."
With the Cumberland sinking from the Virginia attack, the Congress attacked next. Not being able to ram, the Virginia traded broadsides with her. The Congress's shots bounced harmlessly off the Virginia's iron sides. The shells from the Virginia, however, tore through the wooden sides of the Congress, inflicting many casualties. Finally she surrendered, knowing the fight was hopeless against the seemingly impregnable Virginia. The Congress was set on fire, and it burned through the night, finally exploding and sending flames high into the air. As it was late in the day, the Virginia retreated back up the river, ready to return the next day and finish off the rest of the Federal ships.
USS Congress

In this one day the Virginia changed naval history. Although it was known that ironclads were the future of warfare, an ironclad had never fought a wooden ship. The Virginia had shown what ironclads could two. The Virginia had sunk two of the best ships of the United States navy, inflicting 300 casualties, while she remained almost completely unharmed. There was nothing forseeable in the minds of the North prohibiting the Virginia from sailing to any Northern port and blasting it into submission. Stanton, Lincoln's secretary of war, said this:
"The Merrimac will change the whole character of the war; she will destroy, seriatim, every naval vessel; she will lay all the cities of the seaboard under contribution. I shall immediately recall Burnside; Port Royal must be abandoned.... I have no doubt that the monster is at this minute on her way to Washington, and not unlikely we shall have a shell or cannonball from one of her guns in the White House before we leave the room."

Before the Monitor – Development of Naval Technology

We have seen over the past few months how both the Confederate and Union armies began constructing iron plated vessels to either break or preserve the blockade. These construction efforts resulted in the first ironclad against ironclad battle in world history between the Monitor and the Merrimac in March, 1862. Some have mistakenly identified these ships as the first ironclads, but if we look at the naval history of the previous decades, we find this is was not the case. For example, the Young People's History of the United States from 1916 contained this:
Until our Civil War, all ships, even ships of war, were made of wood. Now, they are made of steel. A single sea-fight changed the great ships of the world from wood to steel,— the fight between the Monitor and the Merrimac.
In this post I will go over some of the naval technological development so that we can understand the true significance of ironclads in the Civil War.
Floating Battery from Charleston Harbor
The idea of covering ships with iron was not new. It had been around in various forms for centuries, but there were several restraints on their actual construction. Steam propulsion was really necessary to create a useable ironclad or floating batteries. Wind and sails just did not have the power to move an iron covered ship. Some of the first forerunners of the ironclads were called floating batteries. Floating batteries were ships with heavy armaments intended to defend a stationary position. But some floating batteries were constructed which were capable of movement. During the Crimean War France and Great Britain built iron plated floating batteries which were capable of slow movement. These were used against Russian fortifications, and was one of the reasons they eventually sued for peace.
La Glorie, first oceangoing ironclad

With the success of their floating batteries, in the late 1850s France began developing iron plated ships which were intended for faster movement. In 1859 La Glorie was launched, which has been called the first true ironclad. It was covered by 4.5 inches of iron, and was capable of moving at the rate of 13 knots. She was armed with 36 rifled guns. It was recognized in Europe that these were the ships of the future. Britain and France began to construct large numbers of these new ironclads, recognizing that wooden ships would be useless against them. In 1860 Britain launched the Warrior, a faster and more powerful ironclad.
British Ironclad Warrior today
By the time the Civil War started in 1861, all the nations of Europe recognized the way naval technology was going. Although it had not yet occurred, they could easily guess what would happen when these powerful new vessels met their current wooden fleets. By 1862 Britain and France had 16 ironclads completed or under construction, and Austria, Italy, Russia and Spain were building them as well. As the Civil War began, the Confederacy began to construct ironclads in hope that they would be able to use them to break the blockade of the North. The Federals followed suit and began building ironclads of their own.
CSS Manassas
We have already discussed the Battle of Head of Passes, the first time a true ironclad entered combat. But this battle did not show the full potential of ironclads, since the wooden ships did not put up a good showing. That showdown would not occur until March 9th and 10th, 1862, when the Merrimac struck the Union fleet, and then encountered the Monitor off Hampton Roads, Virginia.

So although ironclads had not proved everything they were capable of until the battle of the Monitor and Merrimac, all the navies of Europe had already guessed it and had many ironclads under construction.

Battle of the Head of Passes

CSS Manassas
One ship built by the Confederacy to break the blockade was the CSS Manassas. It was rebuilt from an icebreaker, and was intended to defend the Mississippi River. It was only 2 ½ feet above the water, and was covered in 1 ½ inch armor. She carried only one gun, and had an iron point on the front for ramming. It was originally built to be a privateer, but the Confederate navy seized it for the defense of the nation.
USS Richmond
She advanced out to battle in the early dark hours of the morning 150 years ago today, October 12, 1861. It was accompanied by a “mosquito fleet,” six small and weak gun boats and three fire rafts. The Union blockade fleet off New Orleans was three wooden sloops, along with two smaller ships. The Confederate fleet's commander, Commodore Hollis, planned to have the Manassas lead and take out the Richmond, the largest of the Union sloops. She would be followed by the gunboats pushing fire rafts, which he hoped would destroy the rest of the Federal ships.
Manassas attacks the Richmond
The Confederate fleet was sighted by a Union sloop, and the alarm flare went up. The Manassas aimed for the Richmond, but the Richmond was tied to a smaller coal ship. She struck a glancing blow alongside, but did not do significant damage. But in the collision of the blow, one of the Manassas's two engines was disabled. At this point the fire rafts were released toward the Union vessels. Seeing them, the Federal fleet cut loose their anchors and moved down river to escape. The firerafts grounded, as did the Manassas. All the Union ships but one also grounded down river. The Confederate's small gunboats fired at the Union vessels stranded on the bar, but although they did get a few hits, they did not score significant damage. The commander of one of the Union fleets panicked, and ordered the ship's magazine destroyed. Thankfully for the Union, the fuse was not successful and the crew returned to the ship.
Map of Head of Passes
Although Hollis was acclaimed in New Orleans as a hero, the ship that was actually the most damaged was the Manassas. The Manassas had been found to be too slow and unmaneuverable, the smaller gunboats too weak to do any damage, and the Federal commanders had not even made a good showing of a defense. Admiral Porter of the Union navy wrote this:
Put this matter in any light you may, it is the most ridiculous affair that ever took place in the American Navy. There is no instance during the war like it. To think that we should have to write of such a retreat is mortifying, but it stands on record, described in language that almost claims merit for the flight of the "Richmond" and her consorts, chased by a ram that was going in an opposite direction as fast as her disabled machinery would take her,— her officers thanking their stars that they got away so easily! There is nothing that can equal the comicality of Capt. Handy's performance—laying a train with a slow match to his magazine, and then hastening away in his boats with the American flag wound around him, and his remarkable antics when he found that his ship would not blow up. This presents an example unmatched in any navy in the world.
This conflict has been forgotten in the light of the more illustrious battle of the Monitor and the Merrimack. Because of the damage to the Manassas the true abilities of the ironclad were not demonstrated. However, the capture of New Orleans was put off until a later date.

Johnston Moves to Join Beauregard

A Train on the Orange & Alexandria Railroad
On July 17th, Johnston 's troops in the Shenandoah Valley were ordered to join Beauregard. Facing Johnson was Patterson, but Patterson had moved so slowly that he had failed to press Johnston . His orders were to keep Johnston from reinforcing Beauregard, but he failed horribly. Johnston was able to combine with Beauregard so that they would outnumber McDowell's advancing army. To make this movement, new technologies were used. The Civil War brought the first widespread use of railroads to transport troops, and this would be one of its first uses. Johnston's army was rushed ontp trains to take them to Manassas Junction, where Beauregard's army was stationed. A journey that would have taken days or weeks on foot could now be accomplished in a few hours. This move would prove likely to change the outcome of the upcoming battle.

Construction of the CSS Virginia

Merrimack
When Virginia seceded, the Gosport Navy Yard in Portsmouth, Virginia was abandoned by federal troops. The buildings and ships were ordered to be destroyed, but one ship sank before being destroyed. The USS Merrimack was a steam frigate that had been built in 1855. Although she had burned to the waterline and sank, the Confederacy was in such a great need of ships they raised her to attempt to reconstruct her.
Burning Merrimack
She was the only large ship with working engines available in the area and it was decided that she would be rebuilt as an ironclad. While ironclads were a new invention, this ship was not the first ironclad as many believe. Several had been built in Europe, and although it was recognized that they would become powerful forces in future wars, they had not seen much combat. Rumors were heard from the North that they were working on an iron covered ship as well, so they set to work on transforming the Merrimack into the CSS Virginia, 150 years ago today. This ship would later prove to the world exactly what ironclads were capable of.
Completed Virginia

Thaddeus Lowe and the Balloons of the Civil War

Lowe
In June, 1861, Thaddeus Lowe demonstrated hot air balloons to Lincoln for use in the military. Lowe was from New Hampshire, and was the son of a cobbler. After attending a chemistry lecture he was so interested in the subject  that the professor took him on as an assistant. After the professor retired, Lowe traveled around the country giving his own lectures. He also began making hot air balloons, and by 1860 he began a leading ballon builder in America. He planned to fly across the Atlantic Ocean in a balloon, and so he tried a test flight from Cinncinati to Washington, DC. His plans did not go very well however, he ended up in South Carolina, a few months after they seceded. He was arrested for a time, but finally was allowed to go home.
With the Civil War at hand, Lowe abandoned the idea of crossing the ocea. Instead he proposed to Abraham Lincoln that his ballons be used for aerial reconisance. He was sucessful, and after his performance at the Battle of Bull Run a ballon corps was formed with Lowe at the head.
