At that time, it was a powerful unit that made the people of Shanghai in the concession feel uncomfortable, and they were not only equipped with machine guns, submachine guns, rifles and other military weapons, but also had an independent detachment of police armored vehicles.

Of course, it can't be the kind of Rolls-Royce wheeled armored car owned by the International Chamber of Commerce, and the group of businessmen on the board of directors will not do the stupid thing of repeating investment, and for the different purposes of use, the patrol house buys a police armored truck made by Ford in the United States.

This armored guard vehicle was originally designed by the United States to be used in its own country. Class and racial tensions in the United States deteriorated dramatically during the Great Depression, with large-scale demonstrations and strikes, which often eventually turned into mass riots. The U.S. police urgently needed a police vehicle that could cope with the situation, and the Ford armored guard car was born.

Converted from the chassis of a Ford six-wheeled truck, the armored vehicle has an enclosed armored compartment that can carry 20 heavily armed police officers, with curved corners on the exterior and vertical side panels without any protrusions for outsiders to climb.

At the front of the trunk is a firepower platform that can accommodate up to six people standing side by side, equipped with high-powered searchlights and machine gun supports, and the top of the cab is also equipped with warning lights, microphones and high-pitched sirens to warn and intimidate the marching crowd.

Because it is a police vehicle, the armor of the trunk is not very strong, but it is thick enough to withstand the civilian version of the Thomson submachine gun, and the safety of the driver is also taken into account, and the front of the cab is also equipped with an armored windshield that can be opened and closed up and down.

In order to increase the intimidation of ordinary citizens, the concession painted the whole body of the truck bright red and gave it the beautiful nickname "Red Maria".

Historically, after the public concession was occupied by the Japanese army, these garrison cars continued to be used by the Wang puppet police, and after the victory of the Anti-Japanese War, they fell into the hands of the national government. At that time, the Shanghai Police Department set up a police motor vehicle team, and these Ford garrison cars were changed to a fashionable name called "Flying Fortress", during the Liberation War, these garrison cars were frequently dispatched to arrest the underground party and revolutionary people in Shanghai, and the unique piercing siren of "Flying Fortress" became an important part of the memory of Shanghai citizens for that period of white terror.

After the founding of the People's Republic of China, these special garrison vehicles did not lose their usefulness, and they were all transferred to the western region at that time to maintain local peace and tranquility.

Now standing in front of the Japanese Army are the two "Red Marias" of the public concession patrol house.

Originally, the two garrison vehicles carried a total of 30 special armed police officers on the Sichuan Road Bridge, led by American patrol officer Lieutenant Stevens, who served in the U.S. Army and participated in the famous Battle of St. Miel, for which he received a Purple Heart.

When the fighting broke out, they heard gunfire as soon as it happened, and Stevens didn't realize that the concession was being invaded, and thought that it was some newly opened shop setting off firecrackers, as usual. The patrolmen all happily talked about the boss being in trouble, and the consequences of ignoring martial law were quite serious, and he would be fined at least 300 yuan, and he didn't know which team of lucky patrolmen would fall into.

Fortunately, the sentry at the Sichuan Road bridge was equipped with telephones, and Stevens's armored car detachment was not caught off guard by the Japanese army. At this time, all the minds of the patrol room were gone, and the alarm was raised by a Chinese duty inspector of the central capture room, who told Stevens that a team of Japanese troops had suddenly invaded the concession and was now attacking the Chinachem Hotel, which was full of important people.

The officer on duty had no command in his hands, so he had to ask Stevens to consider whether he could immediately come to the rescue.

The Americans did not think about it at all, and immediately said that the armored vehicles would immediately attack, and as a retired veteran of the United States of America, he never took the Japanese seriously. Having dared to attack the Chinachem Hotel, the Japanese were clearly going mad, and this was the best chance to make a name for themselves, and his Stevens name would be on the front pages of tomorrow's newspapers.

After passing through the intersection of Beijing Road, Stevens ordered the vehicles to turn left and drive onto Dianchi Road, where the exchange of fire was at the intersection of Nanjing, and he didn't want to rush into the battlefield like this.

What the lieutenant never expected was that his decision to avoid Nanjing Road led to this small armored convoy crashing head-on into the Japanese troops who were making a detour from Dianchi Road.

The Japanese were on high alert at the moment when they spotted the oncoming red armored car, and the machine gunner did not hesitate to pull the trigger, and the bullet shot a string of sparks in the armor plate of the cab window of the "Red Maria".

The thickness of the steel plate could not stop the attack of the military rifle bullets, and the unlucky driver was killed instantly with four bullets in his body. The armored truck sprinted off the road to the left and crashed headlong into the Yeguang Real Estate Company building on the side. The driver of the car behind him hurriedly turned to the right and also crashed into an apartment building on the other side of the road. As a result, two red Marias, one on the left and one on the right, blocked the entire Dianchi Road tightly.

Lieutenant Stevens, who was standing on the platform of the carriage, took a step into the carriage before the Japanese opened fire, and the other patrolman who was standing on the platform with him was unlucky and received a solid shot in the shoulder.

The patrol in the carriage was defenseless against the collision car, and as a result, they rolled on the floor, and everyone present had never encountered such a battle, and for a while the screams and exclamations rang out one after another, and some of the timid almost wet their crotch.

Finally, the patrol officer Stevens was an experienced veteran, he roared angrily and kicked and kicked his subordinates to stabilize the morale of his soldiers, and the lieutenant told his men that they might have collided with the opposing team's roundabout troops, and at this time they were already in a predicament, and in this case, only by fighting hard could they seize a chance to survive.

At the same time, Stevens warned these subordinates that if they escaped at this time, they would not only lose their jobs, but also be disciplined by the Ministry of Works.

Most of the patrol members were Chinese, and they did not lack the courage to fight, and when they met an experienced commander at this moment, their emotions quickly calmed down.

The special forces of the Public Concession had the most advanced ordnance and equipment at the time, and their opponents were armed bandits who entered the concession to commit crimes, often from the army, or with similar backgrounds, all of them were murderous, cunning, daring, and accurate marksmanship.

In mid-July last year, the "Red Mary" of the special armed police had a fierce clash with the Wang puppet police because of the police jurisdiction in the cross-border road construction area, and immediately killed and injured more than a dozen Wang puppet patrols.

Subsequently, in October, in order to catch the Wang puppet assassin who had escaped into No. 76, he simply blocked the gate of No. 76 with a garrison car, and at that time, the concession patrol and Wang puppet agents launched a shootout across the gate, and several people on both sides were killed and wounded.

Now in the face of the Japanese army, these armed policemen actually mustered up the courage to fight back stubbornly with their weapons. Don't look at these are just policemen, thirty people are actually equipped with twelve Thomson submachine guns, and they are all carrying huge 100-round drums, plus the combat distance is less than 100 meters, and the dense firepower actually suppressed the Japanese soldiers on the opposite side.

PS: I'm sorry, I'm busy today, draw the time code, the number of words is not much, please be considerate, and there will be a chance to make up for it later.
