After the Battle of Klushino in summer of 1610 Tsar Vasili IV of Russia was deposed and taken to Warsaw. The Polish-Lithuanian army entered Moscow on September 21, 1610, and the boyars, clergy and citizens of Moscow, in fear of False Dmitry II, accepted the Polish Prince Wladyslaw IV Vasa as new Tsar. But the foreign Tsar was not universally accepted outside Moscow, and the country was ransacked by Poles, mercenaries and gangs of robbers of every nation. In March 1611, citizens of Moscow rebelled against Poles, and the Polish garrison was besieged in Kremlin by the First People's Militia, led by Prokopy Lyapunov, governor of Ryazan. Poorly armed militia failed to take the fortress, and soon fell into disorder: Lyapunov was murdered by Cossack leader Ivan Zarutski. Amidst anarchy and breakdown of central government, citizens of Nizhny Novgorod led by Kuzma Minin assembled the Second People's Militia, under the command of Prince Dmitry Pozharsky. Well armed and organized, Second People's Militia took Yaroslavl in March of 1612 and set up provisional government of all Russia, getting support and provisions from many cities of Russia and Siberia. Getting news that a relief Polish army under HetmanChodkiewicz was approaching Moscow, Minin and Pozharsky entered Moscow in August 1612 and besieged Polish garrison in Kremlin.
First Battle
On September 1, 1612, Polish–Lithuanian forces unsuccessfully tried to break the siege of the Moscow Kremlin, and rescue the Commonwealth garrison under Mikołaj Struś which was present there. To achieve this, they attacked from the west, towards the suburbs of Moscow. Polish hussars, backed by Polish, Hungarian and German infantry, managed to break the Russian lines. At the same time, however, the right wing of the Commonwealth forces was exposed, which was immediately noticed by the Don Cossacks of Dmitry Trubetsky. Their cavalry attacked, managing to disperse the Polish–Lithuanian forces. At the same time, the Commonwealth units in the Kremlin tried to attack the Russian positions, but also failed. On this day, both sides lost some 1000 men.
Second Battle
On September 3 Chodkiewicz decided to attack Moscow via its southern suburb, the Zamoskvorechye District. Some 600 Hungarians infantrymen managed to reach the walls of the Kremlin. They were followed by main Commonwealth units, which however were halted in the narrow streets of the district. After a Russian counterattack, Chodkiewicz ordered a retreat, losing several hundred men.
Outcome
Both battles ended in tactical victory of the Russians. They managed to repel the Commonwealth army, and the garrison of the Kremlin, which had run out of supplies, capitulated on November 7, 1612. News of the capitulation reached Polish KingSigismund III on December 8 at Volokolamsk, less than 30 kilometers away. Upon finding out about this, the king, who was on his way to help the garrison, decided to halt the march and head back to Poland.
