Second Battle of Beruna

The Battle of Beruna of the Narnian Revolution, known generally throughout Narnia's history as the Second Battle of Beruna, occured in Narnian-year 2303, and was the last and most major conflict of the civil war which ended the reign of King Miraz, replacing him with his nephew Caspian X and restoring the Old Narnians' way of life throughout Narnia.

Though the battle was quickly dispersed when Aslan awoken the trees in the book, the Disney movie extended this battle.

Pre-Battle: The Duel of Aslan's How
The Battle began at Aslan's How where the Telmarine Army (commanded by Miraz) and the Old Narnian Army (commanded by Caspian) watched a swordfight between the unrightful Narnian king, Miraz, versus the High King of Narnia, Peter the Magnificent. The Marshal of the Lists for the Telmarines were Glozelle, Sospesian, and Gergiore, who all ploted against Miraz. The marshals for the Old Narnians were Glenstorm, Wimbleweather, and the eldest of the Bulgy Bears.

The duel began when Peter and Miraz entered the lists from the opposite ends, after bowing and saying something to each other Peter beat Miraz a whole pace and a half back. The Crowds began shouting, and Miraz began using his height and weight to his advantage, and sprained Peter’s arm by throwing his weight on Peter’s Shield. Then they circled each other, testing each other’s defenses. It was then that Peter struck first blood when he cut Miraz on the outside of his thigh. The two of them then agreed to a small rest, and Peter had his arm tended to.

Then the two returned to the duel, this time Peter made good use of his feet, keeping out of range of Miraz’s sword, shifting his ground and making Miraz work. Miraz then got a blow on Peter’s helmet, making Peter to fall to one knee. Just as Miraz was about to finish Peter off, Peter grabbed Miraz’s arm as it was coming down, forcing Miraz’s blade to glance down his right shoulder. As Peter and Miraz started fighting hammer and tongs, Miraz slipped on a tussock. Sospesian came in saying Peter killed the king while he was down, convincing the Telmarines to charge the Narnians.

The Battle
After the supposed "illegal move" from Peter during the duel, Lord Gergiore and Sopespian led the Telmarine charge at the Old Narnians. During the stampede and the confusion, Miraz was quietly murdered by one of his own lords, General Glozelle, unnoticed by any others.

After Peter took out Gergiore, the Telmarines sent out their cavalry against the Old Narnians and activated their Trebuchets. After ten seconds however, Narnians who had been charging through recently dug caverns beneath the battle field destroyed the pillars which supported the ground the Telmarine cavalry was charging accoss, causing the cavalry to fall into a giant sink-hole. While the archers attacked, Narnian infantry attacked the cavalry while they were disorderd. The Narnians that were underground then came back up to ground level through two trap dors between the Telmarine infantry and cavalry and turned back towards Aslan's How, completing the pincer. In an attempt to eiliminate the operators of the catapults, Gryphons carrying Dwarf archers flew in close to the Telmarines. However, the Telmarines turned out to be prepared for such an event and shot down many of the Gryphons with Javelin Launchers. Seeing how the cavalry was faring poorly, the Telmarine spearmen moved towards the sink-hole to destroy the Narnians while they were in the open.

When Peter and Caspian saw the enemy phalanx advancing, they tried to retreat into the How. Unfortunatly the Telmarines concentrated their Trebuchets fire on the entrance to the How, destroying it and trapping he Narnians outside. Seeing as there was no escape, the Narnian infantry charged the Telmarines spears, trying to kill as many Telmarines before they themselves died. The Telmarine infantry surrounded the remaining Narnians and began to close in. As the Narnian numbers dwindled Caspian tripped behind Glozelle, but before the general could finish off the Prince, a tree root grabed him from behind and knocked repeatedly against the side of the sink-hole. The Old Narnian army then rallied once they had seen that the trees had come to life again. The trees tore through the Telmarine infantry and destroyed the Trebuchets, and the Narnian army charged the frightened Telmarines, prompting the Telmarine commanders to order a retreat.

The Telmarines fell back to set up a defensive stand on the far side of the Beruna river. However, after Aslan had awakened the River God, it destroyed half of the remaining Telmarine army as it tried to cross the river. After Sopespian was engulfed by the River-God and the bridge was destroyed, the Telmarines surrendered, thus putting an end to the conflict.
