Battle of Mogilev on 27 June 1581.
Less than 1000 men of the Polish-Lithuanian Commonwealth (including 200 hussars under Marcin Kazanowski, ca. 150 medium cavalry under Temruk Szymkowicz and ca. 150 cossack light cavalry under Halibek - as well as armed civilians of the city of Mogilev) - defeated 30000 Russians and Tatars.
Also casualties of Polish-Lithuanian forces were minimal. Defenders of the city lost only 2 wounded people, nobody out of 200 hussars was killed (even though many were wounded - especially by arrows) and only the unit of cossacks under Halibek suffered heavy losses. Casualties of medium cavalry (Petyhorcy) under Temruk are unknown.
Here goes the story:
In June 1581 a Muscovite-Tatar army numbering - depending on source - 30 thousand, 40 thousand or 45 thousand troops + some cannons - invaded the Grand Duchy of Lithuania, in the borderzone strip extending through the cities and towns of Dubrovna - Orsha - Kopys - Szklow, up to the line Mogilev - Radoml - Mstsislaw, advancing towards the main city of the region - Mogilev. Polish and Lithuanian forces in the area were hugely outnumbered, numbering only 1000 cavalry and being considerably dispersed over the vast area.
Muscovite-Tatar forces - as reported by a Polish scout Strawiński - were led by the following commanders (in total 15 commanders were reported by Strawiński):
"Elder voivodes: Mikhailo Petrovich Kaiterov, second Andrei Ivanovich Chvorostenin, etc., etc. (below I quote the full list of 15 commanders in Polish spelling):
wojewodowie starsi: Michaiło Piotrowicz Kaiterów, drugi Andrei Iwanowicz Chworostenin, trzeci Izmaiłów, czwarty Roman Dmitrowicz Buturlin, piąty kniaź Michaiło Wasilewicz Nozdrowati, szósty kniaź Iwan Michaiłowicz Wołchowski, siódmy kniaź Marculey Sczerbati, ósmy Iwan Michaiłowicz Baturkin, dziewiąty Feder Fustow, dziesiąty Michaiło Hliebów Sałtikow, jedenasty kniaź Iwan Boratinskij, dwunasty w stróżowym pułku tatarzyn kniaź Iwan Kulanczuk Czermikoy tatarzyn, trzynasty Wołodimir Holowicz, czternasty Wasiley Ianów, wojewoda kozaków dońskich, piętnasty Iermak Czimofieiewicz, ataman kozacki
After that Strawiński describes the composition of enemy forces (which included 5 Tatar hordes):
"with them [15 commanders] were the Tatar peoples, that is temnikowska, kadomska, kasimowska, woiemaska, swiaskia [Sivash in English] and czobosarska hordes, as well as Muscovites [Russians] - numbering 45 000 [both Russians and Tatars], in addition 1000 Don Cossack and Muscovite mounted shooters [dragoons]."
So in total 46000 (or 45000 if dragoons are already included) soldiers according to Strawiński.
These forces crossed the Dnieper River on 25 June, and advanced towards Mogilev. On 27 June, a Russian army attacked the outskirts of Mogilev. It burned them, after which - as certain Strawiński reported to the king:
"(...) The enemies attempted to approach to the city donjon, with the intention of burning it, but with God's help we prevented this by fire from the castle and from the donjon, having also shooters with arquebuses deployed between the hurdles and inside houses, organizing counter-raids and we were not giving pardon; this way with God's help and with Your Majesty's luck, in the above mentioned outskirts of the city they burned several hundred houses, but did not inflict any damage in men upon us and did not capture any of us, they only wounded two of our men, while suffering a huge loss of life and damage among their own people as the result of our fire, both from the castle and from the city donjon. (...)"
But bravery of the inhabitants of Mogilev would not be enough to stop the Russians, if not the help provided by regular forces - at first by Winged Hussars (one unit under Marcin Kazanowski, numbering on paper 200 horsemen), and 7 hours after Kazanowski, light cavalry (a unit of Petyhorcy under Temruk Szymkowicz, numbering on paper 164 horsemen, and a unit of cossack cavalry under Krzysztof Radziwiłł led by Halibek, numbering on paper 150 horsemen).
Details of the cavalry engagement are known thanks to account of certain Hołowczyński, who on 30 June 1581 wrote to the king:
"(...) The enemy approached Your Royal Majesty's city of Mogilev and burned the outskirts of Mogilev, destroying several hundred houses, and thanks to their hugely superior numbers they almost managed to pour into the city and the castle, but with God's help Your Royal Majesty's military people, units of the Lord of Trakai (Krzysztof Radziwiłł

, of Sir Kazanowski and of Sir Temruk, who managed to mobilize on time, repulsed the attackers and defended the castle and the city by engaging the enemies in battle. (...)"
Also Jan Piotrowski in his account written on 11 July 1581 described those events:
"(...) On 27 June, as lieutenant Markowski reports, 30,000 Muscovites and Tatars approached the city of Mogilev. Even though despicable and paltry soldiers, they almost captured Mogilev, because the hussar unit of Kazanowski alone without its captain, informed about the enemy approaching, hastily advanced to defend Mogilev with just 200 horsemen; they were chasing after them there for 7 hours, in such a way, that they did not let the Muscovites to enter the city. Later another unit under Temruk came with help [164 medium cavalry]. Muscovy, having many of their soldiers empaled, started to withdraw and approaching the Dnieper River, started to cross it. Our forces continued to harass them during that crossing, chasing them away and capturing several prisoners, who were later brought by this here lieutenant Markowski to the king. In that battle the unit of Kazanowski suffered a lot of damage in horses: Muscovites were heavily shooting at them with bows and arquebuses. Also many companions and soldiers were wounded; but nobody [in this unit] was killed, with God's grace. (...)"
But the unit of 150 cossack cavalry under Halibek lost many killed and 3 captured soldiers (captured by Russians were: Gulski, Żbikowski and Kured).
Mogilev survived the Muscovite onslaught. Hastily withdrawing Russian forces marched eastward towards Orsha, burning some villages during their retreat.
Later that year (1581), king Stephen Bathory invaded Muscovy and laid siege to the city of Pskov.
