The War for Novgorod
Kynaz Pukuveras did not really understand his father lengthy and enigmatic final catechism, which included opaque terms such as "Do not make war upon Svjpod if our Military Organization technology is lower than 4". What he did understand was his brother realm in faith was being attacked by infidels, so naturally he decided to make war upon the invading Svjpodians.

(When new reached Vilnius of the war, Novgorod had already lost Novgorod to the Svjpodians.)
While Vinius prepared for war, news so momentous that it echoed all the way from the distant Great Sea to Vilnius made the royal court despair. The infidels have scored another victory over Christians, and whatever the controversy of rites between Rome and New Rome, Catholics were Christians all the same. Orthodox Lithuania did not take the news well, especially when further details trickled in, showing that Muslims won the jihad for Africa... after deposing their own Calipha. Christians failed to triumph against infidels bickering amongst themselves!
An avid Romanophile, Pukuveras kept himself up-to-date on the struggles in New Rome. The Armenian Basileus Vassak Kourkouas was hastily displaced after about 1.5y of reigning, replaced by the Greek Athanasios Argyros. While famous for his hunting exploits, Athanasios was not a hugely problematic ruler like the legendary Justinian II Rhinometos (Slit-Nosed), who ruined the empire he inherited with his madness. Fortunately, Justinian II has been dead for around 3 centuries.
As Novgorod was unable to call for help after the collapse of their messenger system during the conquest of the Novgorod area, Pukuveras chose to invade Svjpod itself to distract the invading infidels. Soon after mobilizing his army, Pukuveras led the Lithuanian host into Svjpod's holdings on the southern Baltic shore, where the two kingdoms meet. There, in the place which would have been called Pomeralia in a different time, Pukuveras learned 2 things. One, Lithuania has not yet reached Military Organization 4. Two, his father had good reason for stopping him from attacking Svjpod because of this.
While not even Vilnius was a stellar place to live in, compared to the sparsely-populated Pomeralian wilds, Lithuania was much less harsh on her children. Which meant soldiers were dying left and right due to various causes within the unfamiliar landscape, forcing Pukuveras into a hasty retreat and into a nasty ambush. Of the 7,000 Lithuanians who marched into Pomeralia, only 4,000 came home.
However, news soon came of the late
Kynaz's sainthood decision. With the blessing of the Paraclete, the Patriarchate of Lithuania declared Montvilas a saint, and his hagiology of making war upon evil and the temptations of Satan was one befitting his warrior's life. With his grave further furnished with holy artefacts and his legend brought up everywhere the church bells toll, many were moved by Montvilas' inspiring life and joined Pukuveras' beleaguered host.
(This is what I call getting the buff you need when you most need it)
Alas, two further developments occurred. The war for Novgorod had come to an end, with Novgorod conquered by the infidels. And on the southern front, a distant relative of the Lithua House, Antanas Lithua, has finally led his army within sight of Vilnius, intent on claiming the throne of Lithuania. Pukuveras, in panic mode, separated his forces, resulting in a tragic and humiliating defeat on the northern front. For the first time since its establishment as a kingdom, Lithuania truly lost a war, and had to concede defeat to infidels. War reparations drained the treasury, and it would seem not even the aura of his sainted father could save Pukuveras from the discontent of the tall and mighty.
But where saintly auras fail, a victory could easily suffice. While Antanas made substantial gains, all of it was because Pukuveras had no forces to send against him, and it was a testament to the swiftness of the northern disaster that when Pukuveras set his sight fully on his wayward relative, the host he sent south still had not made contact with Antanas'.
In the battle that would be celebrated as Pukuveras' greatest achievement in war (though the king himself led only a flank), the forces of Vilnius met and routed the claimant host at Zaslawye, turning the tide of war with one battle. With Antanas chased from Vilnius and the field, the claimant war effort soon lost steam, its armies broken and fleeing towards Crimea, and Pukuveras' grasp on power was secured... for now.
I shall not bore the readers with the details of reconquering the claimant-held southern lands while fighting nomad raiders from the distant Bolghar Khaganate among other things. To sum up the most tumultuous period of Pukuveras' reign, Antanas surrendered less than a year after Zaslawye, and lived out his last days in the Castle of Oblivion, forgotten, gaunt, and harmless to the
Kynaz.
(If the fate of Pukuveras ever hinged on one battle, it would be Zaslawye)
