Who would win in a sea engagement between HMS Warrior and the USS Monitor? Why?

Monitor_vs_Warrior_by_Radojavor.jpg


Here is one excerpt I read already. Please tell me if this sounds right or is it utter hogwash?

"This is an incredible image and it brings up a lot of interesting what-if questions. Ironclad battles at this time were often rather anticlimactic since the abilities of iron armor usually outstripped the destructive capability of cannon technology at the time- they were limited in velocity due to using black powder rather than modern nitrocellulose propellant. The best analogy I can think of would be a land war where everyone is wearing full body armor but carrying a single-shot .22. Virginia and Monitor both survived their first 4-hour engagement with overall relatively minor damage. The Monitor's massive 11-inch guns weren't firing at full charge due to concerns about catastrophic failure since this battle was pretty much it's shakedown cruise, and until a lucky hit on the pilot house's viewing slats the Virginia's 6 and 9 cannons couldn't do much to the Monitor's 9 inch thick turret armor (attempts to ram the Monitor actually only damaged Virginia.)

The Warrior and Black Prince were faster and much more capable of handling rough seas, but from all accounts a river monitor would have had a faster rate of turn due to being much shorter. The Monitor-class ships were also capable of entering waters that the Warrior could never dream of- specifically, shallow, narrow rivers- which gives them a viable escape method from the Warrior's far superior speed. This also gives the monitors somewhat of a logistical advantage in the long run (since I don't think a single battle would decide the fate of these ships) as the larger vessels would be dependent on rarer dedicated harbors to safely resupply and repair whereas a monitor could duck into a river and be tended anywhere that supplies could be moved. In terms of armor Warrior had 4.5 inches of iron armor over 18 inches of teak above the waterline, while Monitor had 9 inches of iron on the turret and a belt that from what I can tell was about 5 inches of dedicated armor over a 6 inch iron stringer. The Monitor's armament was two 11-inch cannon in a traversable turret. Warrior had 26x 4.5 inch cannon, 10x 7-inch cannon, and 4x 8.12 inch cannon in fixed broadside positions which allowed high rates of smaller-caliber fire but only in a rigidly-fixed broadside.

When loaded to full power (as they were after the battle with Virginia when time allowed them to be properly proofed) the Monitor-class ships had cannon far superior to anything on the British ships. With a 360 degree firing arc they could have defeated the 4.5" iron armor on the Warrior, especially at the point-blank ranges for which the monitors were meant to fight (and is depicted here.) However the Warrior was a big ship and barring a hit to the magazines it could have soaked up lots of damage simply by virtue of sheer mass, meaning it would take Monitor lots of time to score a fatal hit with only two guns. If things got too dire the Warrior could have simple dropped sail and, with a good wind, ran at more than twice a monitor's top speed. Conversely since the Warrior had a lot of guns but they were smaller-caliber and mounted high to engage other large, tall ironclads with thinner armor, not low-profile floating fortresses like the monitors. The Monitor's superior armor allowed it to survive dozens of hits from the Virginia's 6 and 9 inch guns and it's low profile let it evade over 100 more but out of the 40 guns the Warrior carried only 14 were comparable in power to the Virginia's. The rest were 4.5" guns designed more to engage wooden tall ships at range, and they probably would have had little effect on the 9" armor of the Monitor. Then there's the question of whether or not the Warrior could even depress it's guns enough to easily hit the monitors at the range depicted here, whereas the monitor's guns are right at the waterline of it's opponent. The US also had numbers on their side- even assuming they would be able to spare both ships in the face of French ambitions, the original reason for both ships- it would have been Warrior and Black Prince vs over 49 Union monitors, many much more advanced than the Monitor-class (15 inch guns, dual turrets, better armor, improved pilothouse, higher speed, etc.) The Monitor itself, the prototype, was laid down in only 119 days and the delivery target time for later ships was 90 days. I can only imagine dozens more would have been built in the face of the threat presented by direct British intervention.

The logical outcome to this particular situation in my mind? The big British capital ships would take severe but repairable damage, having ample time to retreat easily leaving the monitors behind thanks to their high speed and the slow rate of fire afforded by only two cannon per enemy ship. Neither ship here is actually fighting the enemy it was designed to counter so they're both ill-suited for the task. As another poster commented this would probably kick off an arms race with the lesson learned don't get your big ship with thin armor and little guns get close to a little ship with thick armor and big guns. Warrior and Black Prince would come back with heavier cannon (and probably escorted by smaller ships like steam skiffs equipped with spar torpedoes since the monitors lacked the kind of armament needed to deal with multiple small ships) while attempting to use their superior speed and upgraded broadside to kill the monitors at range. In response you'd see more seaworthy Union ironclads like the USS New Ironsides being built to counter, and so on and so forth. "

If the two ships had to fight and could not run, who would win?

Some other questions to consider. This way people can open their minds to more than just one dimension of thinking. Other possibilities should be explored as well.

Who would win between Great Britain and the United States, if the countries went to war, during the Civil War? What were the capabilities of both fleets? Finally, what tactics would they use to destroy each other? What other countries potentially might enter the conflict on either side? What would they bring to the table? I know it is speculation, but I am interested in any feedback. This could have turned into a World War! Thank you!
 
I did not think USS Monitor was all that seaworthy. Great for harbors and rivers, yes, but not the open ocean. Once was a naval vessel, the other was more of a patrol boat. In the neutral area where they could both fight (I guess a harbor), Monitor would certainly have the advantage in firing arc and maneuverability over HMS Warrior.

If the Monitor's guns actually could penetrate the armor of Warrior, then I suppose it could win. I'm used to the story of Monitor vs. CSS Virginia, which was basically just two tin cans denting each other to no effect. If the guns were not at full power, then I could see things differently. However, I still feel there's a general lack of seaworthiness.
 
The two would slug it out for 4 hours before the Warrior would run out of ammo and have to retreat.
 
I'm forced to wonder if an ambitious/reckless British commander couldn't just ram/sail really close to to the monitor, and swamp it completely.
 
Warrior would probably win. The low waterline of the monitor would make it rather unstable and problems with the rotating turret (during the battle with the Virginia the locking mechanism for the turret didn't work so the crew just kept the turret rotating and fired whenever the Virginia happened to come into view.
And yeah, the Warrior could probably just run over the Monitor, swamping it.
 
Yeah I'd have to agree, the Warrior would probably win by ramming or some such, otherwise I don't think one could really hope to sink the other.

The turreted configuration of the Monitor was much better than the Warriors broadside arrangement though. In fact there was a guy in the Royal Navy named Cowper Coles who said he could defeat the Warrior with a much smaller turreted ship. They built 2 ships to test this as i recall, neither of which had good seakeeping qualities unfortunately. (he died when the second one sank in a storm.)
 
With regardsto weaponry, Warrior may not be able to penetrate the armour of the Monitor, but it would have considerably greater weight offire than the Virginia. Would this be enough to threaten to swamp the Monitor outside of ideal conditions?

As for an actual battle, it depends on the mindset of the captains. If calmly followed there would likely be a lot of attempts to drive/bait the Monitor out to sea and let it just sink, while the Monitor would attempt to drive/bait the Warrior to run aground on the coast.

Your post is heavily reliant on a sustained close range battle as shown in the picture. Hoever there would be no motivation for the Warrior to do this unless the cammander is simply out for glory (very possible) and unless they drift to close to shore or have the wind suddenly die it should be quite capable of avoiding the situation.

I thought we were talking about the post-shakedown Monitor which did not have these problems. Obviously, pre-shakedown Monitor wouldn't fare as well.

Ramming would not be as easy as you make it sound--the Monitor was a small target and had a better turning speed, as mentioned in the OP.
 
I think the Warrior would win for a couple of reasons.

I am assuming that this battle is happening in blue water and not brown water. Even after the upgrades, the Monitor class was a glorified river boat. Both Confederate and Union navies realized the value of ironclads for brown water action and harbor defense. So I am forced to assume this as a fleet action where the British are attacking an American harbor or something of that nature.as this is a fleet action it wouldn't just be the Warrior going to battle against the Monitor, but other ships as well. This happened at the battle of Hampton Roads, with other Union ships engaging the Virginia along with the Monitor (not that it mattered for much but they did). So in this battle where a British fleet is engaging the American defenses, the British have a tactical advantage of having more ships and thus being able to have local naval superiority at the battle. This is where the British would be able to overcome their less effective guns. The British ships have much, much larger crews than the Monitor and could do something that neither the Confederates nor Union could do at Hampton Roads, board the enemy ship. Ity numerical superiority, the British would use this at the time still in use tactic to board the Monitor. Even if the boarding parties didn't take the Monitor right away, the smaller crew would no longer be engaging British ships for being distracted. The Monitor was an ineffective blue water warship.
 
Small ship with thicker armor and bigger guns which can aim at opponent's waterline vs large ship with smaller guns which has difficulty at even aiming at the enemy due to its low profile? When the speed of larger ship is useless for it "can not run"? Sounds pretty one-sided engagement if you ask me...

The Monitor is but a prototype of over 50-some other Union-built monitors, and was not designed for blue-water action. Why would it be, the enemy wasn't an ocean away? Since this is an American harbor, won't the Americans have the advantage of location, of having nearby supplies and fresh crews, etc.?

I think your history of the battle of Hampton Roads is a little off. The Union sailing ships engaged the CSS Virginia the day before the USS Monitor showed up. Later in the war, the Union deployed squadrons of monitors; the Union had far more ironclad warships than the British did.

Small ship with thicker armor and bigger guns which can aim at opponent's waterline vs large ship with smaller guns which has difficulty at even aiming at the enemy due to its low profile? When the speed of larger ship is useless for it "can not run"? Sounds pretty one-sided engagement if you ask me...

Not only these factors, but the faster turning speed of the Monitor-class ships means it would have an advantage in maneuverability and could likely avoid being rammed or boarded.



Long story short: I'm skeptical of the claims that the Warrior would be able to effectively board the post-shakedown Monitor, and given the advantage of being difficult to target, having bigger guns, essentially what Yeekim said and I'm repeating, etc. the battle would likely end in a draw (Warrior retreats) or a Union victory.
 
It seems to me that boarding a Monitor would be an extremely efficient method of suicide unless the turret or guns were disabled.
 
Re: Boarding

I have this vision of a bunch of RN sailors leaping aboard with a giant tin opener...
 
I don't think Monitor had serious chance to sink Warrior. She couldn't penatrate Virginia weaker armour. I know that the guns were not fired at full capacity, but this doesn't give us an answer wether they could penetrate if they fired at full capacity. Have in mind that Warrior had supperior armour belt than Virginia. Even if we assume that she could, Monitor had only two guns so even if she delivers dameging blows, Warrior could just escape. She had far more supperior speed. Also ships like Warrior would probably take more than a couple of hits before it sinks.
On the other hand Warrior also could not deliver deadly strike. Although she could do some minor or medium damage which could result in restricted or decresed speed or manuvrability of Monitor, and than Warrior could have chance to ram. Virgina almost succeded and her speed was only 6 knots compared to Warrior's 14.

Generally i think that monitors were quite a succesfull concept, and achieving stelemates and strategic victories over much bigger and expensive ships is quite an impressive preformance.

The Union did run tests with the guns loaded with full charges after the battle, and it could penetrate the iron of the same thickness used on the CSS Virginia. So yes, we do know that the USS Monitor could penetrate Virginia's armor at full capacity.

Also, while the HMS Warrior had thicker armor than the Virginia, it wasn't that much thicker: the Warrior had 4.5" armor while the Virginia had a 3" belt and 4" casements. Compare these numbers to the Monitor's 9". I figure the only ship that has a chance of penetrating the other's armor is the post-shakedown Monitor.



EDIT: I do agree with you that monitors were a novel design--the fully-armored hull, rotating turret with "all big guns" design philosophy over the classic broadside-style ship, etc. were all ahead of their time.
 
fing0lfin, you just beat me to the pinch as I was looking up the engine speeds of the two ships here on my lunch break lol. The Monitor only could do a max of 8 knots and so wasn't a paragon of speed and maneuver.

In refrence to this battle taking place in a harbor, you are in correct thinking that the Americans would have strength in the defense. However, look at the battle of Mobile Bay, after passing the outlying (and poorly designed) forts the Union fleet had to neutralize the Confederate fleet before laying siege to the inner forts. In the same fashion, the Union couldn't attack the Confederate sea forts at Charleston and take city because they couldn't get past the Confederate fleet. As to boarding, just as difficult as it would be for the British to get in it would be even more so for the Americans to get out. Think of it like infantry swarming a tank. And once the British get on board their bombs, which work damn good on more open conventional ships would be even more deadly in the tight and hot confines of a monitor. The point of boarding a ship is less about capturing the ship than taking if out of the fight, don't let the movies fool you.
 
Well I don't think infantry would try to swarm a tank that is still driving and fighting. That sounds like another guaranteed method of suicide to me.

Anyway with every square inch of the Monitor's deck being covered by the turret's 360 degree turn radius all they'd have to do is swivel it around a couple of times like a windshield wiper. Maybe if the British went all Bonzai and swarmed the ship like ants and didn't care about losing dozens of guys before a lucky sailor got a grenade into a gun port or something, boarding could work but I don't think they were that careless about human life.

Plus I don't think the crew of a Monitor would obligingly let their ship sit still long enough for a ship to come up and board it. I mean with the wide spread adoption of engine powered warships the tactic of boarding was sort of instantly obsolete.

By whacking the dudes with the barrel, or by firing the gun to clear the deck? The Monitor had fairly short barrels on its guns, nothing like a modern warship.

The painting in the OP probably depicts the ships a little closer than they would actually engage--I think a boarding action would be far more unlikely than some other posters think it would be (not necessarily directed at you, Bugfatty, just a general comment).

By firing the guns. I couldn't think of a better analogy than windshield wipers. I'd imagine that just being in the area of a muzzle blast of an 11" Dalgren would be quite a traumatic and spiritual experience and there wouldn't be many places to hide from it.

Ummmm, have you ever read about the battle of Kursk, because both the Russian and German infantry were instructed to try and assail a tank because one of the greatest threats to a tank was infantry. Also, first the Monitor's turret wasn't very fast in the moving department and second their stores didn't include graprshot so their guns would be worth squat against boarders. Boarding didn't become "instantly obsolete" with engine-powered ships, and there are scores of examples of this occurring in the Crimean and Civil Wars. Hellz, other purchasing them from England, the most common way for the confederates to gain Commerce Raiders was by boarding Union ships.
