When they lost the war against everyone, first they got beaten by polish civilians
In Uman ;)
then they got beaten by the polish army
Battle of Zhovti Vody, battle of Korsun, battle of Pyliavtsi, battle of Batih show something different ;) The famous polish army was fleeing the battle-fields and a year later Poland was gone on the ends of the Ukrainian spikes. Nota bene: you led no other war at that time :)))
then they got b*tchslapped by Russia
Yeh, they so slapped that the Russians in 2008 raised the whole bruhaha against the Ukraine's celebration of Konotop battle victory when the Russians were crushed.
The Russian Foreign Ministry expressed its "bewilderment and regret" Tuesday over Ukrainian plans to mark the 350th anniversary of the Battle of Konotop next July.
What a bunch of wussies :)
A prominent Russian historian of the 19th century, Sergey Solovyov, described it this way:
The bloom of Moscow's cavalry, troops that happily accomplished campaigns of year 54 and 55 have perished in one day- the victors got only about 5000 captive. The unfortunate were led onto an open space and slaughtered like lambs - that was the agreement between the Crimean Khan and the hetman of the Zaporozhian Cossacks! Never again was the tsar of Moscow able to master an army that strong. In mourning clothes showed himself Alexei Mikhailovich to the people and the terror seized Moscow.
In all the cases whether with poles or russians the big mistake of the Ukrainians was not to go over into their homes and massacre the whole population out so that they thought twice before coming over the next time.
The only reason I can't think of Ukrainian wars is that Ukrainians never stepped up to create their own state until late XXth century.
One reason you can't think (beside obvious reasons) is most likely you have never read Ukrainian history. Open up a book on occasion and you might learn something :)
