Soviet troops liberated large swathes of Polish territory, including the capital Warsaw.

The Polish 1st Army, together with the Soviet troops, took part in combat operations to liberate their homeland. The Vistula-Oder battle was an important part of the military-political mission of military assistance to the British and American allies.

The Battle of the Vistula-Oder showed the growing art of the Soviet commanders and commands in carrying out large-scale offensive campaigns. The superiority of the Soviet high command in the main direction of the assault made it possible for the Soviet army to simultaneously carry out a series of fierce assaults in order to break through the enemy's defenses in several sectors, to quickly throw powerful and rapid troops into the breaches, to pursue the retreating enemy without pause, to prevent him from establishing a defense in the middle and to use the campaign reserve in an organized manner.

The 1st Belorussian Front and the 1st Ukrainian Front, having begun to break through in several sectors with a total width of 73 km, widened the offensive front to 500 km on the 3rd-4th day of the campaign, and to 1,000 km by the end of the campaign.

The depth of the campaign was 600 kilometers. The average daily and nightly offensive speed is 25 km/h. For several days, the pace of attack of infantry corps was 45 kilometers per day and night, and tank and mechanized corps up to 70 kilometers. Such a high speed of attack was the first time in the Great Patriotic War.

The high concentration of forces and weapons in the main assault direction of the various armies was one of the striking features of the Vistula-Oder campaign. In these directions, more than 75% of the combined corps and corps of all arms of the armed forces are concentrated, about 90% of tank corps and corps and mechanized corps and corps, and 75% (1st Belarusian Front) - 90% (1st Ukrainian Front) artillery.

The great art of carrying out the maneuver of the Grand Army was demonstrated during the campaign, the purpose of which was to detour, encircle and crush the enemy's isolated group. The maneuver of Lelyushchenko's 4th Tank Army, which was advanced to the rear of the enemy Silesian group, was an instructive example of such maneuvering.

At the beginning of the campaign, the advance of the 4th Tank Army to the area west of Kielce ensured that Gordorf and Pukhov's troops quickly captured the city and wiped out the entire German Kielce-Radom group.

The extensive maneuvering of not only tank corps but also the combined group armies of various arms was also a distinctive feature of this campaign. At that time, it was a common practice for the troops to boldly advance not with a continuous front, but with a broken front.

The maneuver of the Soviet troops in the Vistula-Oder battle made it possible to encircle the German heavy groups in Poznan, Schneidmeier and other cities, and to crush the German retreating corps and reserves. All this made it impossible for the Germans to restore the long defensive front, and to facilitate the rapid advance of the Soviet troops.

After breaking through the German tactical defenses, the huge armored tank and mechanized corps and campaign corps, equipped with more than 4,500 tanks and self-propelled guns, became the leading force in the offensive of the two fronts.

The conditions for a fast army to enter an engagement are varied.

On the first day of the offensive, the separate tank armies entered the engagements and took part in the breakthrough of the main defensive zone, which ensured the tactical range of high-speed breakthrough of the defense (the breakthrough speed of the 1st Belorussian Front was 8-20 kilometers per day and night, and the 1st Ukrainian Front was 10-15 kilometers per day and night).

The tank armies of the 1st Ukrainian Front (3rd Guards Tank Army, 4th Tank Army) entered the engagement on the first day of the campaign in front of the third position in the main defensive zone, and the tank armies of the 1st Belorussian Front (1st and 2nd Guards Tank Armies) entered the engagement on the 2nd-3rd day of the campaign, when the tactical position of the German defenses was completely broken.

The 1st Army of the Air Force of the 16th Belorussian Front and the 1st Army of the Air Force of the 2nd Ukrainian Front provided great support to the attacking army.

They flew about 54,000 sorties in complex weather conditions, conducted 214 air battles, and shot down more than 200 enemy aircraft.

The 5th and 10th armies of the Territorial Defense Force are responsible for carrying out the air defense tasks of the communication lines and important targets of the two fronts. The lead mechanism is configured in depth echelons when breaking through defenses and chasing enemies. Another noteworthy point of this campaign is that the large water obstacles were quickly crossed in the warm winter conditions of the river with little ice, little snow.

It should be said that the Soviet troops had a good grasp of the basic requirements of the campaign - to advance to the river with a wide front and to force the crossing of the river from the march before the Germans took up defensive positions along the riverbank.

Usually, this will produce good results. As the former West German military historian and former German fascist general Melentin later wrote: "The Russian offensive is developing with unprecedented force and speed.

It was clear that their supreme command had completely mastered the technique of organizing the offensive of a large number of mechanized army groups. What happened in the first months of 1945 between the Vistula and Oder rivers is difficult to describe.

There has not been anything like this in Europe since the fall of the Roman Empire. "For their bravery in battle, 481 corps and units belonging to the 1st Belarusian Front and the 1st Ukrainian Front were awarded honorary titles, and about 1,200 corps and units were awarded medals.

At the end of the river swim, Ye Chao continued to wander leisurely...... Oh, and it can't be said so badly, now there is a more fashionable word called tourism.

As he swam, he swam to the central west of Poland......

Here, there is a city called Poznan.

Poznań, originally founded in the 9th century, was later the capital of Poland. A number of railway trunk line meeting points, highway hubs, large river ports, and developed air transportation.

It is one of the largest industrial, transport, cultural, educational and scientific research centers in Poland and the most economically dynamic region in Poland. Currently, Poznan is striving to develop into the "Zurich of the East".

Poznan is one of the oldest cities in Poland, and it was here that the integration of the Polish state and society began in the 9th century. As the first ruler in Polish history, Boleslav I made Poznan the first capital of unified Poland and made Christianity the state religion in 966.

The year 1253 was a significant year in the history of Poznan, when construction began on the left bank of the Varta River. At the end of the 13th century, Poznan finally had the walls around the city. After two centuries of successful development, Poznan became an important centre for crafts and trade.

At the end of the 16th century, Poznan experienced one of the fastest economic growths, when more than 20,000 people lived in the city. However, the Swedish invasion in 1655 led to more than 100 years of decay after that.

By the end of the 18th century, Poland had been divided between Russia, Prussia and Austria.
