Near Santa Maria, after a brief sweeping battle, the Brazilian inhabitants of the town gave up their resistance, and five or six hundred men, women, and children lined up in two columns under the supervision of Chinese soldiers and gathered in an open field outside the town, waiting for the Chinese troops to arrange for them.

Returning from a meeting in Porto Alegre, Lorraine immediately threw himself into a plan to expel the inhabitants of Brazil.

The war stopped, and the field troops of the Chinese Independent Army, which had been fighting for a long time, lacked repair and replenishment of attrition soldiers, and arrived in Port Alegre These days, three field divisions and two mixed brigades were repaired on the spot, and soldiers with excellent performance were selected from the garrison to replenish the number of troops attrition, and most of the field army soldiers were given the opportunity to repair, only the Fourth Division of Luo Linshan, Li Dawei's cavalry brigade and the soldiers of the Guards Brigade still insisted on tactical training, and the Guards Brigade of the three troops was responsible for guarding Li Mingyuan and the headquarters of the Chinese Independent Army. Training was not slackened at any time, while the 4th Division and the Cavalry Brigade conducted tactical training in order to carry out sweeping operations against the Brazilian population.

Rio Gro Sul is a vast country, with half of Brazil's inhabitants living in castles such as Porto Alegre and Santa Maria, and the other half scattered around the plains and mountains in the countryside.

When the main force of the Chinese Independent Army did not reach Rio Grande do Sul, the large castle settlements such as Erechin, Bage, and Santa Maria were occupied by small detachments arranged by Lorraine Mountain, and the large castles had a large number of Brazilian residents, and the local Chinese detachments stationed in the castles could stabilize the local situation. Far from the core of domination such as castles, the white Brazilians living there are the descendants of poor European immigrants, who need to face the attacks of the remnants of the Indians, diseases and wild beasts, and the cruel living environment makes it difficult for them to survive but also hone their will to live in adversity.

The Brazilian inhabitants in the countryside are wild and difficult to train, and they are shadowed in the armed forces that attacked the local garrisons of the Chinese troops some time ago, and Luo Linshan, who had suffered their secret losses, did not dare to be careless in the face of Li Mingyuan's orders, and after returning to the barracks, he invited Li Dawei and the staff officers in the army to discuss specific policies for dealing with the Brazilian residents.

In fact, before he returned, Li Mingyuan had already roughly arranged the operational method of the sweeping operation, relying on the important strongholds of Baje, Erehim, and Santa Maria to divide the entire Rio Grande do Sul into several operational areas, and a certain number of garrisons would be deployed in each combat area, and then the main force of the sweeping would be concentrated to eliminate the recalcitrant Brazilian residents one by one in accordance with the pre-demarcated theater of operations.

To control the important strongholds, relocate the Brazilian residents and the Chinese immigrants in the combat area to occupy and build, Li Mingyuan gave the strategic arrangements in the general direction of Luo Lin Mountain and the early resettlement plan for Chinese soldiers in the occupied areas, but in practice, Luo Lin Mountain found that it was not so easy.

The occupation of strongholds, the division of combat areas, the appropriate number of soldiers to be stationed in each combat area, and how to ensure that the besieged Brazilian residents in the combat area do not flee are all problems that Rollin Mountain has to face.

With a limited number of troops to carry out the mopping operations, Rollin Hill needed to get his troops as good as possible and complete the task of expelling the Brazilian inhabitants within a month.

The sweep of the Brazilian residents and the resettlement of Chinese soldiers were carried out in sequence, and the sweeping troops here occupied and expelled the Brazilian residents of a clean area, and the subsequent Chinese would quickly follow up and use the houses and production tools left by the Brazilian residents for production and construction.

The Chinese Independence Army relied on looting and capturing the enemy's weapons and materials in the early mobile operations to develop and grow, but a mature army inevitably needed its own solid base and military factories and logistics supply centers to support the troops to update their equipment.

The Chinese Independence Army is full of soldiers, with a total strength of 100,000 troops, and 100,000 troops have gained huge gains in the operations of Peru, Bolivia, and the main force of encirclement and suppression in Brazil, and muskets, artillery, livestock, and grain are piled up in the logistics supply base of the Chinese Independent Army, but no matter how much supplies are used up one day, the fierce battle of 100,000 troops quickly consumes the captured weapons and ammunition, and thousands of miles of long distances are on the way, because the mountain roads are difficult to travel, and a large amount of food and weapons have to be abandoned on the way.

Defeating the main force of the Brazilian army, the power of the Chinese Independent Army reached its strongest period, at this time, it seems not impossible to occupy the three southern states of Brazil and even the state of São Paulo in one fell swoop, but there are huge hidden dangers hidden under the strong German surface of the Chinese Independent Army, the field army has serious non-combat attrition, weapons and ammunition and other logistics materials are exhausted, just because of a huge victory, covering up these defects and deficiencies, if Li Mingyuan is carried away by the victory, After temporarily changing the purpose of the operation and continuing to attack other parts of southern Brazil, the Chinese Independence Army would fall into a desperate situation of being alone in the depths and running out of ammunition, so after perceiving the hidden dangers within the Chinese Independence Army, Li Mingyuan gave up the plan of pursuing Garcia's remaining troops, and quickly reached an agreement with López Jr., so as to lead the troops into Rio Grande do Sul.

Weapons and ammunition were in short supply, and food was only enough to supply the Chinese Independence Army for a few months, and it was no longer in line with the way that the Chinese in South America continued to maintain the whole army as soldiers, so it became a major matter for Li Mingyuan to dismiss the old and weak soldiers in the army and then resettle them in the newly occupied areas for production and construction.

In Rio Gro Sul, the number of Chinese is about 135,000, and the number of first- and second-line soldiers engaged in combat has reached 108,000; among these soldiers, in addition to the main force of the 40,000 field army and the formation of the newly established naval unit, most of the soldiers have to be laid down for production and construction, and at the same time the militia and garrison army have been organized.

Li Mingyuan has done a good job in the short-term planning of Rio Grande do Sul, and the rest of the work naturally needs to be carried out by Luo Linshan's subordinate officers and civil affairs officials, and sweeping away the places where the Brazilian residents are in need of resettlement is the first step in the development of Rio Grande do Sul.

Luo Linshan was not from the remnants of the Taiping Army, he had been in South America for a long time, and he was more familiar with the living habits and combat methods of white people in South America than the senior generals from the Taiping Army.

After being assigned a task that was difficult to carry out by Li Mingyuan, Luo Linshan, Li Dawei and a group of staff officers discussed, combined their suggestions and their own improvements, and finally formulated a detailed and reliable sweeping operation plan.

With Santa Maria as the dividing line, the north and south parts of Rio Grande do Sul are separated, and two operational areas of Bage and Rio Grande are set up in the south, and a garrison brigade is stationed in each of them to prevent the flow and escape of Brazilian residents in the sweeping area: the northern region is divided into two operational areas with the central stronghold of South Cassias and Erechin, and a garrison brigade is also stationed in each, while Luo Linshan and Li Dawei lead the main force of the Fourth Division and the cavalry brigade to garrison Santa Maria, isolating the connection between the two divisions in the southern part of Rio Grande do Sul, At the same time, reconnaissance cavalry will be sent to investigate the hiding places of the Brazilian residents, and once the hiding places of the Brazilian residents are reported in their respective combat areas, a mixed infantry and cavalry force composed of cavalry and soldiers of the 4th Division will set out to encircle and suppress the places where the Brazilian residents are hiding, and then launch a carpet search to prevent a single Brazilian resident from escaping the encirclement.

On the fifth day of the operation, a rural settlement near Bask was discovered by Chinese reconnaissance cavalry, and then the troops who came to sweep surrounded the settlement and captured 800 Brazilian residents, and on the sixth, seventh, and tenth days...... As the garrisons were deployed and the cavalry patrols tightened, the Brazilian residents hiding in the countryside were found and captured, and on the thirty-first day, the last Brazilian settlement was found near Santa Maria, and the month-long sweep came to an end.
