The Don Army was in Hermosilio, but due to the steepness of the Rocky Mountains and the Mexican Plateau, the 7th Brigade of the Don Army did not advance much in this area. Not all Spanish armies www.biquge.info like before, in the face of the powerful Tang army chose to retreat, and in Obregón, the Tang army was met with desperate resistance from the Spanish colonial army.

In this battle, the offensive force of the Don army was only about 600 people in a reinforced battalion, and the Spaniards relied on the fortress of Obregón to hinder the offensive of the Don army. The strength of the Spaniards was about half that of the Tang Army, with only three or four hundred people, and many of them were recruited Mexicans, and their combat ability was relatively low.

However, the commander in command of the Spanish army was adamant, believing that he could lead the defenders to defend the fort of Obregón, which was very strong. They had relatively ample supplies, and the fortress of Ofregon was indeed quite strong and difficult to defend.

The Tang army rampage on Mexican soil for more than a week before it encountered a resolute enemy, and it was also vigorous to face the battle. However, in the beginning, the siege was not particularly smooth. Since the 7th Brigade is a lightly armed force, it is not equipped with a large number of heavy weapons like mechanized infantry. In terms of artillery, Datang's howitzers are equipped with ammunition to penetrate the city wall, but the Seventh Brigade has completely relied on manpower and mules and horses to travel long distances from China to Sonora, and it is impossible to transport too heavy siege artillery. In order to be able to fight in the mountainous plateau area, the artillery of the entire 7th brigade even abandoned 105-mm howitzers for each infantry regiment, and only the artillery battalion of the brigade, which painstakingly pulled 18 howitzers from a large number of mules, was the most important support fire of the whole brigade, and the main firepower provider of the artillery of the regimental infantry regiment became the 81-mm mortar of the Don.

The Don army that attacked Obregon It is a battalion-level formation, generally an infantry battalion will have 3 81mm mortars, because it is not convenient to carry, so only one 81mm mortar was brought, but the battalion's machine gun company has a total of 8 60mm mortars, which belong to the fire platoon of each company and the machine gun company of the battalion. There are also a number of individual bazookas. In fact, such firepower is convenient to transport, although the range is very limited, but for supporting the offensive operations of several hundred people, 8-10 artillery pieces are already very sufficient.

It's just that a weapon like a mortar, because it is a curved smoothbore weapon, has a low muzzle velocity, a small firing range, and poor power, and is more effective for dealing with the enemy behind the cover and for trench warfare, but it is not so easy to deal with relatively strong fortifications. The fortifications of Obregon were built relatively successfully. Built of stone bricks and reinforced, small-caliber mortar shells were hit through a curved trajectory, but they could not blow up the fortifications.

The infantry battalion's direct fire was a number of 40mm rocket launchers, and it was also equipped with armor-piercing rockets against fortifications, but the range was relatively close, and if you wanted to shoot pillboxes, you obviously had to shoot at a relatively close range. This requires friendly forces to cover, after all, on pillboxes. The Spanish defenders also had some artillery to defend the city, and their small arms were largely replaced by rifled guns with higher rates of fire and longer ranges.

The battalion commander of the Don Army did not consider it necessary to fight for his life. Come and take the fortress. In fact, the Tang Army did not have a clear requirement for the extent of the Seventh Brigade's breakthrough, and the goal of the operation was to largely clear the resistance in the Sonora, Chihuahua, and Durango areas, so that the Tang could establish basic de facto control over the area. In terms of specific time nodes, there is no requirement, and the Tang people do not have a clear time estimate of the entire war. I don't want a quick victory, the goal is to take the land I want safely.

However, despite this, the Tang army took advantage of the fall of night to try a night attack on the Spanish defenders' fortress. Unlike the Tang Army, which has stronger field combat capabilities, it has all kinds of lighting fixtures and flares. Although the Spaniards also imported some flashlights from the Tang people, there was no way to use high-power strong lights in places where there were no generators.

So the Don army approached the fortress in the darkness of the night from a direction where the Spanish defenders were relatively weakly defended. This group of soldiers carried two 40mm rocket launchers and managed to remain undetected by the enemy at a position of 200 yards. The combat quality of the soldiers of the Tang Army is also very high, and this kind of work should actually be regarded as the work of the special forces, and the soldiers will not be ambiguous in the future.

The Don soldiers successfully fired rockets at the Spanish fortress, and the explosions and loud noises frightened the Spanish soldiers who were also trembling and in charge of the defense. However, the luck of the Tang army was not good, the fortifications built in the form of bastions had good defensive power, and the power of the two rockets was not too impressive, so although the rockets caused some damage to the fortifications, they did not achieve the expected effect.

The Spaniards reacted, and the defenders began to fire indiscriminately in this direction, adjusting the muzzles of the city's guns. However, in such a poor visual environment, the effectiveness of artillery and shooting decreased a lot, and it was also because of this that several Tang soldiers also successfully withdrew from the vicinity of the fortress without damage and returned to the Tang army camp behind.

After this unsuccessful night attack, the Tang infantry battalion no longer tried to attack the fortress without heavy firepower, and even later drew out a company of troops to defeat several surrounding towns and villages that resisted. As for the Spaniards, although they saw that the Tang people did not try to attack the city at all, they did not think that the Tang army was cowardly, so they went out of the city to seek war, and just stubbornly waited for reinforcements.

However, this entrenchment did not last long, and the infantry battalion of the Don Army attacking Obregun reported its lack of heavy firepower to the regimental headquarters, and the regimental headquarters immediately dispatched 120mm rocket launchers and 81mm mortars belonging to the regiment, and after a day and a half, reinforcements arrived. And the Spanish fantasized reinforcements did not even have a shadow.

The Don army quickly tried to knock open the walls of the fortress on two sides and captured it in suppressive fire, and the Spaniards, although the resistance could not be considered weak, did not last long before being defeated and surrendered. After Obregón was breached, the Seventh Brigade also won victories in other places where the Spanish were stationed in Solano, and a large area west of the Rocky Mountains to the Sonora Desert basically fell into the hands of the Tang Dynasty. The Spaniards have been in business for hundreds of years, but the collapse of the building is only a matter of moments. (To be continued.) )
