It is the work of military scientists, especially modern military engineers. They spent many years in the area and eventually chose this location to build a fortress that would play a decisive role in a possible future defensive war for the colony.

The engineers of the Academy of Military Sciences have made full use of the unique terrain and landform here, combined the performance of existing weapons, and built a nearly perfect defensive position here.

The entire fortified area of the fortress was well fortified, and the enemy had to completely conquer the fort before the defenders could force the enemy to engage the Imperial Army of Marnerocco on extremely unfavorable terrain, perhaps a protracted engagement, accompanied by heavy casualties.

The entire Sarmira fortified area covers an area of about 19 square kilometers, and the defensive front is 7.5 kilometers wide. The fortress was built along the river, long from north to south and wide from east to west, and the main fortifications faced the north and west sides, the two main directions in which the enemy might attack.

The northern defensive position of the fortress is a circular defensive strip built on flat ground, with the Yanar River in the back, and a curved outer moat extending from the river to the central area of the fortress. The railway bridge from the interior of the colony to the coastal port city of Para crossed the northern part of the fort with the central area. The area consisted of a large number of fortified forts, and the blockhouses were covered with barbed wire. The main fortification of this area is a roughly triangular masonry fortification (fortress north fortification), covering an area of about 3 hectares and a wall height of 6.5 meters. To the south of the fort there are mainly flat land and swamps, with outer moats on the north side and the Yanar River on the east side.

The southern side of the fortress plunges deep into a dense tropical forest that is difficult for the large corps to pass. The terrain here is mainly flat and swampy. The main fortification on this side is a hexagonal fortress with a side length of 400 meters and a wall height of 5.5 meters (Fortress South Fort), which is also a storehouse for supplies and a large amount of ammunition supplies. This fortress, together with the nearby fortifications of three small ring walls with a radius of 100 meters, formed the main defensive position of the fortified area on the southern side. There are also a large number of pillboxes and barbed wire belts in this area. Due to drainage problems, no trenches were dug in these low-lying perimeter fortifications.

The central area of the fortress is based on the Salmira Heights, and the core position of the fortress is on the high grounds. The railroad passes on the edge of the highlands, and this section of the railway has been purpose-built as a four-lane railway, with several armoured trains maneuvering to support the defense. On the heights there were the main artillery positions of the fortress, and three layers of trench barbed wire and machine-gun pillboxes formed three outer fortification belts, each of which was dotted with machine-gun fire points. The density of machine guns is extremely high, with three to five Gatling guns every 100 meters. The core fortress of the fortress is a triangular masonry fortress (fortress core fortress) with a side length of 6.5 meters and a height of 6.5 meters at the rear of the three fortifications.

Behind the central area of the fort was a sparsely forested riverside lowland of about 4 square kilometres, from which the defenders could station reserves, place supplies, and maneuver troops, both at this position and on the opposite bank, with crossings across the river.

1.5 kilometers due west of the edge of the central area of the fortress, there is a small high ground with a relative height of more than 30 meters. The engineers used the surplus building materials to build a square masonry fortress (West Fort) here, with a side length of about 100 meters and an outer wall height of 3.5 meters. Serve as the outer support point and guard post of the fortress. It is surrounded by flat land, which is easy to defend and difficult to attack.

After the fort was built, experts from the Imperial Academy of Sciences of Marnerocco simulated the battle process under various conditions through no less than 100 war games: as long as the defensive forces were in place, the enemy forces attacking the port of Para would be held back here for at least two months. By then, a sufficient number of reinforcements have landed in the harbor, and the counterattack will begin at the fortress, and the enemy will be driven back to the landing site step by step until they are driven to the sea. Sarmira Fortress, you can be trusted.
