Located in the northwest of Haiti, Tolty Island covers an area of 180 square kilometers, more than 10 times the size of Feilong Island.

After occupying Torti Island, Chen Sen and Hou Taiyuan transferred their main forces from Feilong Island to Torti Island, leaving only 120 men, a sail warship and three armed merchant ships on Feilong Island as a small supply base and warning point for the Chinese Independence Army in the Caribbean.

In September 1868, the Spanish Revolution broke out, Queen Isabella II was overthrown, and the news reached the Spanish colony of Cuba, and the calm situation was broken instantly. Blacks and native whites were secretly linked, small-scale riots continued to occur, and the Cuban colonial government was in a state of flux.

With large-scale turmoil in Cuba imminent, Chen Sen stepped up his training of soldiers to prevent the Cuban turmoil from affecting him, and on the other hand, he sent personnel disguised as merchant ships to deliver news to Rio Grande del Sud to inquire about Li Mingyuan's next steps for the movement of Chinese soldiers in the Caribbean.

When the war between the Brazilian Empire and Bolivia and Peru lasted for more than a month, the emissaries sent by Bolivia and Peru first arrived in Asunción, the capital of Paraguay, to persuade Paraguayan President Andrés López Jr. to join the anti-Brazilian coalition.

After the Chinese Independence Army left Paraguay, López Jr. sent troops to attack Mato Grosso, but the Paraguayan army did not take advantage of the resistance of the local Brazilian army and subsequent reinforcements, and only occupied some inconsequential land.

After temporarily settling the border dispute between Paraguay and Bolivia, he joined the anti-Brazilian coalition, and the three parties signed an agreement to increase troops in the border area at the same time and cooperate with each other to launch an attack on Brazil.

Brazil's main forces are stationed in the area near Rio Grande do Sul and in the country, and although there are many soldiers stationed on the borders of Bolivia, Peru, and Paraguay, they are scattered and garrisoned in the long border area, and under the large-scale attack of the troops of the three countries, they have suffered considerable losses, and many small strongholds have been conquered.

The stalemate was broken by the adventurous offensive of Bolivia, Peru, and Paraguay with all their forces, and the danger of the loss of the main forces of the Brazilian Empire was immediately apparent.

At the same time, the envoys of the Chinese Independence Army arrived in Rio Grande do Sul, and after three days of consideration, Li Mingyuan finally decided to join the alliance and send troops to attack Brazil.

The Chinese Independence Army was short of elixir, and after arriving in Rio Glan do Sul, it only purchased a part of the ammunition from the Netherlands, Belgium and other small European countries at a high price, and the total amount of ammunition could only support a medium-sized war.

There was still some time before the fleets that had gone to Europe to purchase machinery and ammunition returned, and the British, hostile to the Chinese Independence Army, banned the sale of weapons and supplies to Rio Grande do Sul.

The perilous situation of the Chinese Independence Army did not improve, and it was at any time facing armed intervention from the British, and an attack on the Brazilian army at this time was undoubtedly a risky adventure.

After the original plan to occupy Rio Gür Sul, the Chinese Independence Army (CAA) went on the defensive, and then used military strength to force the Brazilian side to recognize the fact that the Chinese Independence Army occupied Rio Gür Sul, and the two sides achieved initial peace, while the Chinese Independence Army took advantage of the precious peace time to actively import Chinese workers from Cuba and North America to increase its own strength.

However, the situation changed too quickly, Li Mingyuan did not expect that Bolivia, Peru, and Paraguay would break the stalemate in the war and invade Brazil proper.

It was difficult to decide whether to enter the war or not, but the news from Europe and the Caribbean strengthened Li Mingyuan's determination to send troops.

When the revolution broke out in Spain, Britain's strategic focus was naturally put into Europe, and there was news from Europe,

British Prime Minister Benjamin Disraeli was impeached by the opposition, and the position of prime minister was not guaranteed, and the successor prime minister was replaced

Liberal leader William Eurt.

William Jurter advocated better conditions for workers and economic reforms at home, and was less interested in continuing to expand his overseas colonies.

Shortly after Benjamin's impeachment, British warships off the coast of Porto Alegre lifted the blockade of the port, and the Chinese Navy was free to enter and leave the coastal area of Rio Grande do Sul.

When the danger was lifted, Li Mingyuan immediately ordered the Chinese fleet and land troops to launch an attack on the Brazilian army from land and sea, respectively.

September 12, 1868

The Chinese flotilla raided Florianópolis, occupied the coastal ports,

On September 14, the Chinese troops attacking from South Cashias attacked Krazhs and wiped out the local garrison of 3,000 men.

On September 17, the Chinese fleet raided Joinvia, and a Brazilian ironclad anchored in the harbor did not have time to escape, and was sunk by three Chinese Independence Army ironclad ships, a total of 23 large and small ships in the harbor were sunk 8, and 15 wooden warships were captured.

In the Battle of Via, the Chinese fleet attacked the Brazilian fleet with superior water forces, but still paid twelve wooden ships sunk, one ironclad ship was heavily damaged, and two ironclad ships were lightly damaged.

The Chinese fleet trained at sea for more than two months, and although the crew learned to operate the warship and some basic naval tactics under the training of Prussian instructors and some captured Brazilian naval officers, they were still a long way from becoming a real army.

If the loss of the Chinese fleet in Via, the Brazilian Navy is also greatly damaged, the loss of more than 20 warships, especially the sinking of an ironclad ship, resulting in the Brazilian Navy only leaving the last ironclad ship to support the façade, and the Chinese fleet that has experienced a naval battle has increased its actual combat experience, plus there are two ironclad ships that can be put into operation, in terms of comprehensive strength, the Chinese Independence Army's maritime combat strength surpassed the Brazilian Navy for the first time, and before the new ironclad ships were replenished, the Brazilian Navy lost its maritime deterrent power against the Chinese Independence Army.

If, after the Battle of Invia, the land forces continue to advance,

On September 21, Chapeco was conquered, and on the 25th the main Brazilian forces stationed in Santa Ratina were surrounded at Blometi.

On the 29th, the Chinese Independence Army launched a general attack on the besieged Brazilian army, and after a day of fierce fighting, at 10 o'clock in the morning of the 30th, the Brazilian defenders surrendered, and the state of Santa Catarina was declared completely in the hands of the Chinese Independence Army.

Leaving a part of the force to sweep away the remnants of the Brazilian army in Santa Catarina, the main force of the Chinese Independence Army continued to advance, and by October 4, the Kuala Prava area in southern Paraná had fallen under the control of the Chinese Independence Army, and the main force of 40,000 troops had reached the city of Curitiba, the capital of Paraná.

Facing enemies on all sides, they lost their land even again. Under the oppression of various factions in the country, Emperor Pedro II of Brazil had no choice but to find the British to intervene, and made negotiations with Bolivia, Peru, Paraguay, and the Chinese Independence Army.

Britain actively expanded its economic sphere of influence in South America, and it was not in Britain's national interest that the situation in Brazil continued to deteriorate, so after Brazil's request for intervention, British warships quickly arrived in Curitiba to stop the Chinese Independence Army's attack on the defenders in the city.

The war lasted more than 20 days, the Chinese Independence Army newly occupied more than 100,000 square kilometers of land, the stored ammunition and war materials were exhausted, and the offensive momentum reached the limit, even if the British did not interfere, Li Mingyuan did not intend to continue to expand, and the encirclement of Curitiba, including the occupation of Paraná as much as possible, was to increase the weight in his hands and prepare for negotiations with Brazil for greater interests.

The British intervened in the war, and the Chinese Independence Army, Paraguay, Peru, and Bolivia quickly halted their advances and sent representatives to participate in the British-led negotiations.
