Castillo de San Miguel - Palacio Presidencial - Buenos Aires
The secret reports of a possible open revolt seemed to be exaggerated. The Unitarios were uncommonly quite in the last month and so were the other oppositionell groups. Rosas wasn't deluded that they were loving him out of a sudden (?). They weren't even supporting him, he guessed. But many of them were fearing him for sure. His secret service, the mazurka, excelled at its duties. And the exilation of nearly a dozen liberal writers and journalists did the necessary to force many liberals into hiding. His influence was increasing day by day and the federal flag was flying over nearly every fortification in the United Provinces. To show his generosity he allowed the intellectual and liberal teacher Sarmiento to return from his exile in Chile to San Juan. But first he made sure that Sarmiento wouldn't become a threat in the future. Sarmiento was forced to promise to give up his affilation with the Unitarios. And the Mazurka had a very close look on his activities and teachings.
Rosas had to admit that it was a very comfortable situation he found himself in. And it became even better a few hours ago when a despatch from the argentinean ambassador in Montevideo reached him. The ambassador informed him, that Uruguay forged an military alliance with the brazilean Emperor Dom Pedro II. and send their whole army northwards to support the Imperial Army against the piratini rebels. His generals and ministers were debating about this new fact since they were assembled in the great salon and informed about it. That was merely three hours ago. Some were a angry about the Uruguayans and called them traitors for their alliance with brazil, was the banda oriental for them little more than an autonomous province. Others were thoughtfull, perhaps frightened by the alliance which easily could turn against the United Provinces. Rosas himself was wether frightened nor angry. He was calm, listening to the opinions of his ministers like a marmoreal statue and weight out the pros and cons of the loomin opportunities. But in the inside he was smiling bright, he was smiling victoriously. The brazilians had made the first step. And the first mistake, Rosas thought. Now with the Uruguayan army joined the war on the behalf of Emperor Dom Pedro II. the Piratenesi war of independence was no longer a brazilian domestic affair. This was a nearly perfect opportunity to bring the rebellious Uruguayans back into the Federation and a even better opportunity to weaken Brazil. Rosas was sure that the debates in the great salon would continue till the late evening but he was also sure that a messenger would be on his way to Porto Allegre before dawn.

In Brazil the war was named "Second Cisplatinean War". In Argentina it was first called "Rio Grande Conflict" but later it was called "Guerra del Banda Oriental" or "2nd Argentinean-Brazilean War".
Plaza de Mayo - Montevideo
The sun stood high at the sky and the masses were waiting down there at the plaza. It was sixtynine long days since President Rosas left together with 10.000 soldiers the military camp near Colon. And now it would be only a case of a few minutes to end this campaign. It was a strange campaign anyway there were not a sign of military resistance. To the contrary, in some towns and villages they were welcomed as liberators. The rural populace supplied them with water and food cheerfully. His troops advanced very fast and without any problems. And even the capital, Montevideo, surrendered without a single round fired. President Oribe seemed not to be very popular, perhaps of his military alliance with the brazilian Empereror? A thing that has to be checked by the Mazurka Rosas noted. The mass cheered again but they became more and more nervous. Time to bring this to a dignified end. He turned around to the other assembled men in the hall. "Gentlemen now it is time to face the truce. Sign this proclamation and bring it to a dignified end so the history books might commemorate you as true patriots and responsible statesmen." Rosas said to the assembled Ministers. "And what if we refuse to?" one of them asked. "If you really had a choice you would have prevented my appearance, wouldn't you?"
One by one signed the proclamation. In a few minutes Uruguay would have ceased to exist and the Banda Oriental would be a province of the Argentinean Federation again. With a loyal governor and a thankful populace. Hopefully General Gutierrez was equally successfull in his attempt to convince the uruguayan army to surrender. Manuel de Rosas already could hear the cheers they would gave him.
69 Days after the declaration of war Montevideo and the uruguayan government surrendered to Generalcaptain and President Juan Manuel de Rosas. The Argentinean Army faced little to no resistance on their advance to Montevideo.
Road to Pelotas - Pelotas Province
General Gutierrez was successfull, too. The Banda Oriental taken back without a single fallen soldier. Rosas was very pleased. This would really be a great propaganda success for him. Shortly after he received the news of the surrender he ordered Gutierrez to encamp near Pelotas and to wait for his arrival. A meeting of the general staff was in need to coordinate further operations against the Imperial Army. The Imperial Army was as strong as the piratini and the argentinean forces together. So no side would probably win this war by a few succesfull battles. But for a longer war whether Argentina nor the Piratini Republic had the needed rescources of men, guns and money. And the large brazilian navy could blockade the argentinean harbors and rivers easily. Bare stripped of most of his strategic options Rosas was desperately thinking about a way to end this war with the largest gains and fewest lossest possible. Slow but steadily a quite odd idea came to his mind. An idea that wouldn't please General Gutierrez but he would execute it, no doubt. Rosas was quite curious to see the look on his general's face when he reveals him that he and his men will ride behind the enemy lines straight to Rio de Janeiro to occupy it while Rosas and his two infantry divisions would be supporting the piratini army around Curitiba and Sao Joao.

The daring ride of the 1st Cav. Div. under the command of Gen. Gutierrez. The Division left Curitiba in July in an attempt to occupy Rio de Janeiro unattended. They reached it in early November.
Battlefield near Cacador - Vila do Principe Province
Rosas looked down to the battlefield were hundreds of dead, brazilian and argentinean soldiers alike were lying. It was a hard and long fought battle against superior numbers. The Imperial Army attacked with nearly 20.000 men, his own troops were mot quite as half as many. But thanks to the sloppy hills of the "Vila do Principe" Region they were able to withstand the enemy. he was sure that he didn't lost a quarter of his men whereas the Imperial Army was nearly slaughtered to the last man. Some three thousand of them were in a wild retreat to the sulfur mines of miranda. Possibly they would build up some kind of deseperate last defense. Nothing to worry about too much. For now it was time for a drink and for some 18.000 burrials.
*due to a savegame crash i had to replay the second phase of the war. Thats why the maps aren't the same.
