Huascar Part 1

The story of the ironclad in battle takes us next to the Pacific, and the monitor Huascar. Built by Laird Brothers of Birkenhead for Peru, she was commissioned in 1866, slightly too late for the war she'd been ordered to fight. 1,870 tons, 220 ft long, and mounting 2 10" guns in a single turret, she was a reasonably powerful vessel for the day, although she was essentially a coastal vessel. The belt ranged from 2.5" to 4.5", and her maximum speed was 12 kts.


Huascar as completed

Her first decade was quiet, but in 1877, a civil war broke out, and Huascar was seized by rebels, who began to run her up and down the coast, extorting "contributions" from coastal cities. This irritated several of Peru's trading partners, most notably the British. In response, they dispatched two of their ships, the unarmored cruisers Shah and Amethyst, to put a stop to it. They encountered Huascar on May 29th, 1877. The resulting battle was indecisive. Peruvian gunnery was poor, while the 60 to 70 hits the British made on Huascar did little damage. The only effective hit was one shell that pierced the 3.5" plate near Huascar’s stern.


The Battle of Pacocha

This battle was also notable as the first ever use of the Whitehead torpedo1 in combat. Huascar had closed with Shah as if to ram, and Shah fired a torpedo. Unfortunately, torpedoes of the day were so short-ranged that it was ineffective.2

Shortly after the torpedo missed, Huascar’s colors were shot away, and there was a lull while the British thought she might have surrendered. The ship's crew hoisted a second flag, and the battle resumed. However, Huascar was close to shore, and fear of hitting the town of Ylo stayed the British fire until dark, when Huascar slipped away. She surrendered to government forces the next day, and the rebellion flickered out.


Huascar in 1879

Two years later, another war broke out, between Chile and an alliance of Peru and Bolivia, over control of an area rich in guano on the Pacific coast.3 The fate of a piece of the Atacama Desert, one of the driest places on Earth, would be decided by what happened at sea. The Bolivians didn't have a navy, while the Peruvian navy was heavily outmatched by the Chilean. Theoretically, they had four ironclads, the seagoing Huascar and Independencia, and the coastal Manco Cápac and Atahualpa, while the Chileans only had Cochrane and Blanco Encalada. However, the Chilean ships were the better part of a decade newer, and significantly better armed and armored, while the Peruvian coastal monitors had been built for the US during the Civil War and were slow and unseaworthy. The only advantage the Peruvians had was that Chile lacked a drydock in which to clean the hulls of their ironclads, meaning that Huascar and Independencia had a speed advantage.


Miguel Grau

Huascar was under the command of Admiral Miguel Grau, who had previously been her commander between 1868 and 1876. He had returned to command her and the Peruvian Navy as a whole, with a plan for Huascar and the rest of the fast Peruvian ships to raid the Chilean coast, denying them control of the sea.


Arturo Prat

The first major naval battle of the war was fought off the Peruvian port of Iquique, which the Chileans had been blockading. Huascar and Independencia fell on the blockading Chilean ships, the wooden Esmeralda and Covadonga. Despite being heavily outmatched, Esmeralda's captain, Arturo Prat, chose to fight. Huascar attacked Esmeralda, while Independencia engaged Covadonga. Prat took Esmeralda in close to Iquique, where shallow water prevented Huascar from closing in. Eventually, the Peruvian forces ashore assembled artillery and drove Esmeralda back into deeper water. A boiler then burst,4 limiting the Chilean ship to only 3 knots.


Huascar and Esmeralda in action off Iquique

The battle was an interesting contrast. Chilean gunnery was excellent, but their guns, the heaviest a 40-pounder, were ineffective. The Peruvians only fired 40 rounds from the 10" guns during the four-hour engagement, and only got one hit, which destroyed Esmeralda’s engines and killed her engineers5. Grau then ordered Huascar to ram, although the attack was executed poorly, and little damage was done. Prat attempted to board the ironclad, but only one man followed him. Grau called on them to surrender, but Prat refused, and was shot down.


Prat's death aboard Huascar

Grau rammed again, and the only difference from the previous attack was that this time a dozen Chileans managed to get aboard Huascar. They were no more successful than Prat had been in taking the ironclad. However, the combined rammings, as well as the few hits, had disabled Esmeralda, flooding her magazine and leaving no ammunition for her guns. Huascar’s third ramming was successful, sending Esmeralda to the bottom. Only 63 of her crew of 200 survived.


Esmeralda beginning to sink

Prat became a national hero in Chile. Four warships and the Chilean Naval Academy were named after him. Grau became known as "The Gentleman of the Seas" for his conduct. Immediately after the battle, he made sure that all of the survivors of Esmeralda were rescued. Later, he returned Prat's body, and his personal effects, to Prat's widow, along with a letter of condolences. During a later raid, he made sure to give the crew of a merchant ship a chance to evacuate before destroying it, despite the proximity of Chilean pursuit. He was celebrated in Chile for this, as much as in Peru.

This was not the end of Huascar’s career, a tale I'll tell next time.


1 The Whitehead torpedo was the first practical self-propelled torpedo, and the ancestor of the modern torpedo.

2 I'm not sure of the exact model of torpedo used in the battle, but the most advanced Whitehead of the day had a range of 800 yards.

3 This is sort of South American military history in a nutshell. A major war, fought over bird poop. It wasn't the first one, either.

4 This was a fairly common problem with powerplants of the era

5 Probably. There may have been more hits, or hits from Huascar’s unarmored guns. My source is unclear.

    Today at Naval Gazing:
    Part 1 of the story of the Peruvian ironclad Huascar.

    • Andrew Hunter says:

      I gotta wonder: is there a particular reason to care about the Huascar? While the story is interesting, this strikes me as a very niche topic even among pre-dreadnoughts. Am I missing the larger importance of Peru here?

      Also, post request: the rewrite of your missile defense post, because this has been coming up as a topic offline from various friends of mine who assert carriers are all doomed, and I’d like a better reference.

      • gbdub says:

        I enjoyed it. There weren’t that many ship-to-ship battles involving ironclads (Lissa was already covered, and Hampton Roads is already known to anyone with a passing interest in the subject). So this was new and interesting to me.

      • bean says:

        Basically, there were very few ironclad battles, so I looked into this one and found it interesting.

        I’ll look into doing a light update on the carrier doom posts, but a full rewrite is not going to happen soon.

      • Harry Maurice Johnston says:

        OT, but have you seen The Last Jedi? There’s a question here that you might have insight into. (Well, at least if you subscribe to the theory that the space combat in Star Wars is based on WWII naval warfare.)

        • bean says:

          I haven’t and won’t. I refuse to acknowledge Disney’s destruction of the EU, unless Mara Jade is in this movie.

          In terms of the question, not really. Trying to hit a ship was hard enough, hitting a specific spot didn’t really happen. The closest I know of is when they went after Yamato, they tried to hit just one side with torpedoes to make her more likely to capsize. Musashi had been hit from both sides, and took a lot more torpedoes to sink.

          • Lillian says:

            They didn’t destroy it, they just set it aside into its own alternate universe. Also frankly, do you really think anyone making Star Wars sequels would bind themselves to decades of EU material? George Lucas himself never gave a shit about the EU when he made the prequels or the Clone Wars show, he wouldn’t have given a shit about it if he’d chosen to make sequels. Nobody would have, it was already a full time job just getting the EU authors to write stuff that was in line with the rest of the EU. It was inevitable that EU would be ditched as soon as someone with full creative control started making stories set after Return of the Jedi. It’s unrealistic to expect otherwise.

          • bean says:

            They’re still selling the books, but they’ve closed it off to new content, and are developing the new stuff with almost no reference to the old. Thrawn’s reintroduction is an exception, but that’s mostly because he’s so amazing that they couldn’t keep him out. My suggestion was to do it like a comic book adaptation, and keep the best bits. There was a lot of garbage, but also some absolute gems.

          • Harry Maurice Johnston says:

            Thanks.

            Amusingly, I generally take the exact opposite tack, and refuse to acknowledge anything but the movies. (That includes Clone Wars, of course; I’ve seen some episodes because the kids watch it, but though they’re sometimes fun to watch, I don’t think of them as really being part of the story. I think the word is “headcanon”?)

            … I think that’s mostly about scope, though. Canon that’s got far too much detail for me to possibly take it all in may be more realistic, but that’s not really what I’m looking for. Perhaps I’d have gotten past that if the first few EU novels I tried had been more engaging, or if I’d had more free time back then.

            I can sort of understand that. But Star Wars was what I did in high school before I got into aerospace. So I threw lots of time at it. And there were some really good novels in there, too. I reread the Thrawn Trilogy a couple years ago, and was blown away by how good it was. There’s also a lot of absolute dreck.
