The Soviet Union repeatedly proposed to the Spanish government of Jose to release its "neutral" people, but to no avail, and the negotiations eventually broke down. At 10 a.m. on April 20, the Soviet Union was forced to declare war on Spain. Immediately afterwards, Spain did not show weakness, and at 15 o'clock in the afternoon of the same day, it issued a war warning to the whole country and declared war on the Soviet Union at the same time.

Theoretically, the USSR was actively prepared to declare war on Spain. As early as March 1935, the Admiralty of the USSR drew up a plan for a possible war with the Jose government forces in order to help the Catholics unify Spain. In reality, the military is not really ready for war, the process of mobilizing the army is very chaotic, and even the training of volunteers is simply insufficient.

In addition, the army faced the threat of the German army on the Western Front, and there was a serious shortage of troops, so the veteran volunteers who had fought for many years on the Iberian Peninsula were especially valuable.

Late at night on April 20, the Soviet expeditionary force in southern Europe, led by General Lomonlosov, quietly left A Coruña and searched for the inland city of Punferada. Between the black lights and blind fires, it happened to meet the northwest detachment of the Spanish government army led by General Carvaliero. Both armies were not mentally prepared and rushed to meet the battle.

After a scramble of scuffle, both sides desperately tried to retrieve the remains of their respective soldiers, find the fulcrum of the battlefield, and deploy artillery positions.

Just eight hours after the outbreak of the war, all EU member states reacted by declaring a joint response, and on April 19, the Seven-Nation Alliance, which had been left behind on the Iberian Peninsula, was the first to enter a state of first-class combat readiness.

At the same time, Marc Vida's troops, receiving an encrypted telegram from the Hansa Felter Palace on their way back home, also quickly changed course and landed in the port of Barcelona.

The Third International, led by the Soviet Union, formally and the European military alliance led by Germany, began to clash hard, and the clarion call for war had been sounded. All of a sudden, the countries of the European Union entered the war, and Bulgaria, Germany, Denmark, Norway, Sweden, Hungary, Romania, Turkey, Iraq, Iran, Afghanistan, Arabia, Egypt, Italy, Spain, Portugal, and even the Polish Independence Army in the Soviet-occupied areas began to unite to face the Soviet Union.

Technology has made countries around the world zero-distance, but war has alienated mankind even though they are neighbors.

On the border between Germany and the Soviet Union, on the Vistula River in Bialystok, at 21 p.m. on April 21, Rommel was speaking to his troops before launching a general offensive.

“…… This is the first battle after we declared war on the Soviet Union, and it is also the most crucial battle, so I suggest that you do not take the enemy lightly in the battle, pay attention to intensive cultivation, chew and swallow slowly, fight while pondering, and accumulate lessons and lessons in the battle, so that we can study and refer to it when attacking large and medium-sized cities. In a word, time is not an issue, I will give you enough ......"

At about 23 o'clock, under the cover of night, the three infantry battalions of the 982nd Infantry Regiment of the German 11th Army, which had been stationed in the middle reaches of the Vistula River for a long time, and the Tyrol Speer tank company under the 1st Armored Division of the 10th Panzer Army, suddenly regrouped and suddenly moved to two secret garrison bases in Shekerki, northwest of Bialystok, and Suprahir in the northeast, and quickly entered a state of attack.

Bialystok is close to the border of the Soviet Union, is a relatively lax defense of the Soviet city, but also a very critical traffic chokepoint, once the German army occupies Bialystok, it is equivalent to cutting off all the retreat routes of the Soviet army deployed in the Warsaw area, hundreds of thousands of Soviet troops can only fight alone, and become the German army's plate of dishes, the turtle in the urn.

At two o'clock in the morning, a red flare pierced the darkness and drew a dazzling semicircle in the sky above Shekailki.

"Forward!" Lieutenant Tyrol Speer turned on his walkie-talkie and whispered orders to the two attacking detachments. Suddenly, the motor roared, and the iron rushed wildly, straight to Yavistok.

The Fritz Witte infantry company under the 11th Army followed closely behind the Speer armored vehicles and advanced at the same time towards Bialystok with a rapid attack.

At this time, CIA agents who had been hiding in the city in advance also began to raid all corners of the city and cut off the telephone lines between the Soviet army and the outside world.

All the officers and men of the 191st Infantry Division of the Soviet Army stationed in Bialystok were sleeping soundly, and the dense guns woke them up from their dreams, and they were immediately at a loss and in chaos. The division commander, Major General Vdorov, did not know what was happening, so he bounced off his bed and hurried to the window, and when he opened the curtain and looked out, the northern part of Bialystok was already in flames, gunfire was raging, and occasionally one or two cold bullets hit his windowsill, bursting out with sparks.

It was clear that Germany had already begun a major offensive against the Soviet Union. Vdorov was suddenly shocked, hurriedly dressed and belted, and prepared to organize a counterattack. Suddenly, the phone rang suddenly, startling him, and he hurriedly grabbed the microphone.

"Where? Speak quickly! Vdorov asked eagerly.

"A large number of German troops were found in the north of the city, and they were covered by tanks, and they were advancing in multiple ways, and now they have a fierce exchange of fire with our troops defending the city."

"Immediately organize a counterattack, and be sure to repel the German attack before dawn......" Vdorov was unclear about the situation, and was just about to make a combat deployment, but the telephone was disconnected, and he still couldn't get through when he pulled it back. Furious, Vdorov threw down the phone and went straight to the command post.

To the northwest, the 982nd Regiment of the 11th German Army carried out a multi-pronged attack, with three companies of the 1st battalion flanking the Soviet troops out of the city from the right flank; The 7th and 8th companies of the 2nd Battalion ambushed the German troops out of the city from the left flank; The 6th Company flashed past the Soviets in front of it, and under the cover of a tank company led by Lieutenant Mesut Siegfried, it went straight into the city, so that the Soviets could not look at each other.

To the northeast, the third battalion also marched through multiple sorties and interspersed in between. The fourth company left the road to the city from the left to attract Soviet firepower, lure the enemy out of the city, and encircled and annihilated. The third company left the road to the city from the right and attacked the rear of the Soviet troops in Bialystok; The Speer Tank Company in the center and the 1st Infantry Company of Werther advanced rapidly into the city along the road into the city, and joined forces with the 6th Infantry Company of the 2nd Battalion and the Siegfried Tank Company in the central square.

According to the pre-war deployment, if the Soviet troops on the right flank do not leave the city, the 3rd Infantry Company and the 4th Company will flank the headquarters of the Soviet Army in the northeast on both sides, and then sneak attack Vdorov's division headquarters and forward command post from the rear.

At this time, the 3rd Regiment of the Soviet Army was far from the north of the city and belonged to the active offensive type of troops. However, in the case of unclear circumstances, it is possible that the Soviet army will take advantage of the opportunity of the German siege to sneak attack the German Northwest Battalion, however, the Northwest Battalion has already been fully dispatched, leaving only Major Gabili Tucker, the commander of the 2nd Battalion of the 1st Division of the 10th Panzer Army, and a small number of soldiers to guard an empty shell and use the radio to lure the Soviet troops to attack.

According to the pre-war deployment, the German army and the Soviet 3rd Regiment may encounter unexpectedly in the west of Bialystok, but as long as the 6th Company and the Siegfried tank company move fast enough, the 3rd Soviet Regiment will not escape the fate of being surrounded and annihilated by the German army.

The battle was very fierce, and the commander of the 2nd Battalion of the 1st Division of the 10th Panzer Army, Major Gabili Tucker, held on to the northwest battalion, luring the enemy out of the city on the one hand, and providing mobile and powerful fire reinforcements to Speer Company and Siegfried Company at any time.

In order to minimize the damage to the city's buildings and civilian casualties, the entire siege armament was very simple and monotonous, and the use of large-caliber artillery was not even considered.

As commander-in-chief of the Battle of Bialystok, General Rommel hoped to quietly take the small city on the Polish-Soviet border, and then build a strong advance fortification, first as a chase lock to strangle the Soviet army in Warsaw, and then as a material transit base for General Hoffmann to implement the Barbarossa Plan.

Capture the city is as important as protecting it, and as a result, the attacking forces face a number of unexpected difficulties.

At 3 o'clock in the morning, three companies of the 1st Battalion of the 982nd Regiment ambushed the 3rd Soviet Regiment, and the battle on the west officially began, and the whole of Bialystok ushered in a sleepless night.

The main battlefields of Germany and the Soviet Union began. Hoffmann was about to make all-round contact with the Soviet Union's 3 million troops with 4.2 million German troops on the Eastern Front, and at this time, the Great Strangulation of more than 7 million troops on the entire European Union and more than 6 million troops of the Third International of the Soviet Union had sounded the horn.
