Francisco Solano Lopez was president of Paraguay from 1862 to 1870. He led the country during one of the most devastating defeats in all history – the War of the Triple Alliance. Here, Erick Redington continues this fascinating series by looking at the events in the War of the Triple Alliance, including the Battle of Tuyutí and the Battle of Curupayty.

A depiction of the Battle of Curupayty.
With Marshal Lopez's advance into Corrientes stunted, he knew that pushing all the way to Uruguay was no longer possible. He had achieved much by aggressively invading the Allied Powers. Their armies had been thrown back on their heels, causing increased dissention between the Brazilians and Argentinians, Lopez's only real hope of victory. A wealth of materiel was captured by the Marshal's army aiding the war effort immensely. The small Paraguayan industrial base would have difficulty throughout the war supplying the army with the materiel it needed to fight. The small Paraguayan nation was proving itself to be very dangerous to its larger neighbors. To some, Lopez looked brilliant. To no one more so than the Marshal himself.
The Allies knew they would have to control the rivers in order to maintain their supply chain. The first Allied target was Humaitá, called the "Gibraltar of South America." They knew that as long as the fortress held out, they would not be able to advance further into Paraguay and take the capital, Asuncion. The Marshal knew this as well. He was determined to use every effort to defend the fort. But he knew that Humaitá needed further reinforcing. Therefore, the best strategy would be to delay the Allies as long as possible in order to improve the fortifications. In the process, the Allies would further bleed, and potentially, greater dissention would grow between the Brazilians and Argentinians.
The Marshal also knew that Argentina was fragile at this time. President Mitre had assumed office only a few years before, after yet another civil war. Lopez knew that there were many elements within Argentina who were very sympathetic to him and were perfectly happy to see Marshal Lopez create a strong Paraguay. To these Argentinians, Paraguay was the wrong enemy at the wrong time. The right enemy would always be Brazil. The war would be used throughout as a weapon to attack those in power in Argentina. President Mitre himself was tired of the condescension with which he was treated by the Brazilian officers. They saw him as just another caudillo in a long string of caudillos ruling Argentina. The Marshal hoped that if he could inflict a few further defeats on the Allies, one or both would be willing to come to the peace table and Lopez could get a peace he could live with, rather than the partition and exile that the Treaty of the Triple Alliance called for.
The Marshal Counters
The Brazilian naval commander, Baron Tamandaré would use his fleet to advance further up the river system to allow the Allies to invade Humaitá. When the Allies made a landing at the town of Riachuelo, Lopez sensed an opportunity. The Marshal was not a man to sit back and just take what was coming, so he ordered his fleet to attack the Brazilians. The Paraguayan navy was heavily outnumbered. The Brazilians had better armored ships with more guns. None of this mattered. What mattered was élan. Lopez would fling his navy in a night attack against the Brazilian fleet and in one brilliant move end the threat of an Allied offensive by having his sailors board the Brazilian ships under the cover of darkness, capture them, and then sail the new prizes back up the river to reinforce the Paraguayan fleet.
Of course, this is not what happened. The ships arrived after sunrise. The Paraguayan commander ordered his ships to pass the Brazilian ships and fire on the ground troops. The Paraguayans would lose more ships and have to retreat upriver. It was a disaster for the Paraguayan navy. Marshal Lopez impetuously ordered his fleet to attack an enemy that heavily outnumbered him with a confusing and frankly ridiculous battle plan to not only defeat the Brazilians but also augment his own fleet. Why did he do this? As we have seen, it was in the nature of the man to take risks and wager everything on bold, Napoleonic, plans. As someone who believed he was a military genius, he believed his plans could work. As a brutal dictator in charge of a police state, no one was brave or foolhardy enough to tell him otherwise. Due to this, a sizable part of the Paraguayan fleet that could have been used in the defense of Humaitá was lost, and future defenses were weakened.
By 1866, the Allies were finally prepared to begin what they saw as the war-winning offensive. The Allies crossed the Paraná River and entered Paraguay. The Marshal was a believer in the offensive-defensive strategy. He did not make a general, theater-wide offensive, but he began launching localized counterattacks to make the Allies keep their guard up and slow their advance. This was in keeping with the Marshal's character, but it was also the sound military move. The Marshal knew this would be a war of attrition. He had to make the Allies bleed. He needed to cause further dissention. Passively waiting to be strangled would only lead to being strangled. He had to fight.
The local counterattacks, while not leading to battlefield victories, worked their intended purpose. The Paraguayans were able to slow down the Allies, stopping their advance at Estero Bellaco for a time. The Marshal began to grow more confident. He had been mostly successful in his strategy so far. With his increasing confidence grew his willingness to gamble. He now began to envision knocking out the Allied army with one decisive blow. When the Allies began advancing again, Lopez decided to strike the blow. The bloodiest battle in the history of South America began, the Battle of Tuyutí.
Tuyutí
With the Brazilians on the left, the Uruguayans in the center and the Argentines on the right, the Allies were drawn up in a flat, swampy area. The Marshal decided to focus his attacks on the Brazilians and the Uruguayans. Lopez had a very low opinion of Brazilians, and the Uruguayans were the smallest contingent. Initially, the Paraguayans made gains, however the Brazilian artillery would seal the fate of the Paraguayan army, and the Allies came away with the victory. The importance of the victory was not that the Allies won the battle, but that it had been so deadly.
Statistics from the Paraguayan army at this time are problematic at best. Due to the dictatorial nature of the country, and the importance that Lopez placed on propaganda, reported casualty figures from the Paraguayans can be taken sometimes with a grain of salt. The best estimates for battlefield losses were 6,000 dead and 7,000 wounded out of an army of about 25,000 men. The Allies lost over 5,000 men out of about 35,000. For the Allies, the losses were terrible, though replaceable. For the Paraguayans, this was a national catastrophe. Based upon prewar population, the losses in this battle represented over 3% of the people in the entire country. These men represented the cream of the large pre-war army the Marshal had accumulated and led into Argentina and Brazil. His army would never recover. Never again would the Marshal order a mass attack on the Allies.
With victory comes overconfidence. The Allies, having achieved a major victory now began to advance more rapidly against the Marshal. Where other men would draw back in the aftermath of such a catastrophic defeat, Lopez was as defiant as ever. The Paraguayan army would go on to defend itself well against Allied advances. However, at the Battle of Curuzu, the Paraguayans were defeated again and finally Marshal Lopez was growing concerned. He decided to try a different tack, one which he had not utilized so far: diplomacy.
The Marshal Tries Diplomacy
With the Allies on the move, and getting closer to Humaitá, the Marshal hoped to capitalize on the war-weariness of his opponents. He unexpectedly invited the Allied leaders to a conference to try to end the war. The Brazilians wanted nothing to do with this conference and refused to negotiate with the Marshal. President Mitre, however, decided to meet his enemy. For Mitre, beset by political opposition at home, facing rebellion in outlying provinces, and weary over his own conduct of the campaign (he was supreme Allied army commander, after all), Mitre wanted to find a way to end the war. For Lopez, this represented a wonderful opportunity. Despite his reputation as an insane warmonger, it was said that in person the Marshal could be very charming and a great conversationalist. He was very well read and quick-minded. For Lopez, this was finally his chance to divide the Allies, get Argentina to leave the war, and then take on the enemy he hated, the Brazilians. And he failed miserably.
Accounts of the meeting vary, with some saying that the conversation was amicable, and others saying the two men got into an argument. Either way the conference was a failure. President Mitre told President Lopez of his determination to abide by all clauses of the Treaty of the Triple Alliance. This included the article demanding the removal of the Marshal from power before any peace could be had. Lopez could have agreed and lived a comfortable life in exile in Europe or North America. Instead, he refused. He would fight on to the bitter end. And that is exactly what would happen. No peace, but war, war to the knife.
After the failure of the conference, Mitre decided to restart the offensive and attempt to deal the killer blow, reach Humaitá, and from there to Asunción. The invasion of Paraguay was on. The Allied army approached the Paraguayan army entrenched at Curupayty. The Paraguayans had used the truce to improve their fortifications and build further defenses. They had brought in artillery and reinforced the trenches. The Paraguayans only numbered about 5,000 men, a quarter of the advancing Allied force. In their confidence after Tuyutí, many in the Allied camp believed the Paraguayans were on their last legs and ready to fall apart. This overconfidence led to Mitre preparing a battle plan whereby the Brazilian navy would shell the Paraguayans from the river, and once softened up, the Allies would launch a grand assault to rout the enemy. Once the fleet had finished the bombardment, Mitre ordered the men in.
The Battle of Curupayty can be likened to other thoughtless slaughters like Cold Harbor or the Somme. Allied troops went in and were massacred. The Paraguayans only lost about 50 men in the battle. The Allies, however, lost about 9,000, according to the best estimates. It was a shocking and devastating loss, but it could have been worse for the Allies. The commander of the Paraguayan army was not Marshal Lopez. He would never expose himself to battlefield danger. That was not his way. The field commander was General José Diaz, a good commander in his own right, but he operated within the Paraguayan system of nothing is done without the dictator's permission. Even considering the casualties, the Paraguayans were still outnumbered and outgunned, but they had morale on their side. If they had counterattacked and pursued the Allies, a decisive, perhaps war turning victory could have been achieved. Diaz was not stupid. He was not going to take the initiative and incur the wrath of the Marshal. The Allies were allowed to withdraw back to their entrenchments. Here the war would sit for longer than any of the participants had anticipated. For the Allies Humaitá would have to wait. Recovery from the embarrassment of Curupayty would take far longer than anyone expected. They had much bigger problems at hand.
On the Pale Horse
Part of the original defense plan of Marshal Lopez was utilizing the geography of Paraguay to slow the Allies. Much of the country is located in tropical, low-lying swamps. These swamps bred interminable swarms of mosquitos and other insects. The mosquito was, and still is, a primary vector to transport infectious disease from person to person. For the Paraguayan troops, malnourished and under equipped, disease was a fact of life. For the Marshal, there was no ability to import medical supplies. The traditional Paraguayan cure-all for everything was yerba mate, which was obviously ineffective against infectious disease. Every man lost to disease was a man out of the gun line for the Marshal. There was very little he could do to stop the epidemics though.
With the defeat at Curupayty, the Allies needed to rest and regroup before another advance. Camp life at this time was dull and unsanitary. Given the geography of the area the Allies found themselves, and the filth of the camps, it is no surprise that epidemics began amongst the Allied troops. Dysentery, cholera, and yellow fever were some of the worst. The conditions in the camps, coupled with the terrible defeat the Allies had taken, would lead to much needed changes within the Allied army, but this was small comfort to those who had been stricken.
Out With the Old…
After Curupayty, the squabbling between the Brazilians and Argentinians only grew worse. The Allied field commander, President Mitre, was called a bungler for directing one of the most lopsided losses in modern military history. Mitre was not happy either. He was growing tired of field service. Rebellions were breaking out against his rule in the outer provinces of Argentina. Many within his own government wanted peace. He believed in the necessity of the war still, but he did not believe that he would be the man to lead it. In January 1868, Mitre would leave his army and return to Buenos Aires.
Also out at this time was the President of Uruguay, Venancio Flores. He was also worn down with campaigning and would leave the army. His term as president was ending anyway, and he was to turn over his powers to a new leader from his Colorado Party. He would be assassinated four days after leaving office. The crime was never solved.
For Marshal Lopez, these changes symbolized a weakening of his enemies' resolve to make war on him. What he did not know was that with Argentina mostly out of the war, and Uruguay effectively out of the war, the Allies would finally have solved the one major disadvantage they suffered through compared to the Paraguayans: unity of command. And that unity would come in the form of Luís Alves de Lima e Silva, the Marquis de Caxias.
