In the autumnn of 1570, the Russian 'lydkonung' Magnus advanced towards Reval (modern day Tallinn.) with an army of 25,000.^[1][2] The Swedish defense was led by Gabriel Oxenstierna and Carl Henriksson Horn, who is described as a brave and courageous.^[1] Magnus had brought with him a large amount of cannons, which were his foremost weapon. Unfortunately for the Russians, their forces were not suitable for storming fortresses.^[1][3]

At the same time, a certain Livonian man by the name of Tiesenhusen marched towards the fortress of Weissenstein.^[3] He had previously made himself known for being particularly brutal, with there being rumours that he had drowned his sister for her wanting to marry with a writer.^[3][1]

The assaults against Reval by the Russians were not successful, since the Russian troops were not trained in sieges, and Sweden was able to supply the city from the sea.^[3][1] Since the Russians lacked a fleet, they had hoped that Denmark would assist them in the siege by blockading it, however, this does not occur, since Denmark signed a peace treaty with Sweden in the year.^[3] During January, the Russians plundered over the entirety of Estonia, but the siege of Reval did not improve.^[2] In late February a letter was thrown into the city, it tells them of the peace treaty signed with Denmark. In celebration of this outcome the defenders made a successful sortie against the Russians.^[3][1]

On 16 March Magnus burned his camp outside of Reval and began to retreat, the entire affair costed Magnus 6,000 men.^[4] On the same day, Tiesenhusen lifted his siege of Weissenstein.^[3] When it was clear to the Swedes that the siege was lifted, Clas Henriksson Horn made an attack, he killed many roaming Russian troops.^[1][3] Tiesenhusen was also caught off guard by 300 Swedish knights at Ubagall, where his entire force was killed and the majority of his supplies were taken by the Swedes.^[1][3][2]

In late 1571 Russia is attacked by the Tatars, who manage to burn Moscow. This results a period of peace in the Baltic.^[3]
