Annales seu Cronicae Incliti Regni Temeriae, which roughly translates to "Annals or Chronicles Celebrating Temerian Rule", is a tome written by Jarre sometime after the war with Nilfgaard which talk about the Battle of Brenna.
Not far from the battlefield, where that terrible battle between almost the entire North was facing almost all of the aggressor Nilfgaard's power, there were two fishermen villages - Old Butts and Brenna. However, since Brenna was burned to the ground, people used to talk about the "Battle of Old Butts". Today, however, it is referred to as the "Battle of Brenna" for two reasons - First, Brenna is now restored and is now a prosperous settlement, while Old Butts was abandoned by its inhabitants a long time ago and is now overgrown with nettles and weeds. Secondly - the original name in the context of that grand and tragic struggle seemed extremely awkwar, as if it were not enough that roughly thirty thousand unfortunates gave their lives but with their butts, that were old. So in historical literature the military has taken to calling it the "Battle of Brenna" and not just in our writings but in Nilfgaard's who have many more sources than ours.
Those who are familiar with the local surroundings can easily imagine the situation better than someone who has to rely solely on cartography to find the settlement of Brenna. It was to this settlement that the royal army arrived, in truth there was no settlement because during a battle the year before. Elven commandos burned it to the ground. It was there on the left flank that the Redanian contingent, commanded by Count de Ruyter took a position. He had eight thousand men, infantry and cavalry. The center of the army was located under the hill, which was later called Gallows Hill. On this high ground stood King Foltest's constable, John Natalis which gave him a perfect view of the battlefield. Below him were grouped the main strenght of our troops - twelve thousand Temerian and Redanian infantry formed into four square units, beyond which were arrayed ten banners of heavy cavalry. In reserve where three thousand Maribor infantry under the command of Voivode Bronibor. From the southern shore of the lake, which the local residence called Gold, which meandered down to the Cholta, were deployed the units of our right flank- The Volunteer Army of Mahakam dwarves, eight squadrons of light cavarly and factions of the great condottieri, the Free Company. The right flank was under the command of Adam Pangratt and the dwarf Barclay Els. At a distance of nearly two miles across from the royal army, the Army of Nilfgaard was mobilized under the command of Field Marshal Menno Coehoorn. It's armed populous stood like an iron wall, regiment after regiment, company after company , squadron after squadron, as far as the eye could see. And thought the forest of banners and halberds you could see that their position was not only wide, but also deep. Their army was about forty-six thousand strong at that time, however, only a few people knew this. Which was fortunate, because the determination of many of our soldiers did not waver at the sight of the immense power of Nilfgaard. But even the most bold of heart had theirs poundings faster under their armour, because it was obvious that a difficult and bloody battle was about to begin here soon and that many of those lined up here would not see the sunset.
The morning was cloudy, but the sun pierced the clouds to explicitly remind us of the passing hours. The wind picked up, the flags and banners fluttered like a flock of birds rising to depart. Before us the Nilfgaardians were still, and all began to wonder why Filed Marshal Menno Coehoorn did not give the order to attack...
On the left flank and in the center a fierce fIght still leased, but even thought the Nilfgaardian army was hard and persisten, they broke upon the King's army like a sea wave breaks against the rocks. For there stood the brave soldiers from Maribor, Vizima and Tretogor and the grim landsknechts, the mercenary professionals, the cavalry did not scare. And there they fought, truly like the sea against the rocks and continued to fight, and it was not possible to guess who would win, because even thought the waves beat against the rocks, it didnot weaken or disappear and it stood there between the raging waves. Like an old hawk, who knows where to fall and attack, so Field Marshal Menno Coehoorn knew where to strike. With the iron fist of his army, which cosisted of the Deithwen division and Ard Feainn division he struck at the enemy lines above Golden Pond. That place was fiercely defended by the troops from Brugge, but they were less armed and armoured and morale was low. They managed to hold off the attack of the Nilfgaardians. In a breath of relief two flags of the Free Company under the command of Adam Pangratt arrested the Nilfgaardians, but both sieds paid dearly in blood. However, the dwarves of the Volunteer brigade were facing a terrible siege and the threat of encirclemen, which would threaten to tear apart the formation of the royal army. Seeing the danger threatening, however, John Natalis, attentive as a crane, understood what was happening at the time, and without waiting he sent a messenger with orders to Colonel Els...
Fiel Marshal Coehoorn's plan failed - his counterattack against the flank was stopped by the heroic Vizima infantry and Voivode Bronibor, even though they paid a bloody tax. While the men of Vizima resisted the strong pressure from Nilfgaard on the left flank the enemy continued on the right. soon our troops gained the upper hand on the right flank as well, where the dwarves and tough condottiere resisted Nilfgaard's grip. From our ranks arose a triumphant cry, and in the hearts of our fighters enter a new spirit. The confidence of the Nilfgaardian soldiers fled, their arms grew heavy and their strenght ebbed. Some of them retreated, other still resisted, but now uncoordinate, in scattered groups, soon besieged from all sieds. Then the enemy commander realised that the battle was lost. Surrounded by his loyal officers and knights, they brought him a new horse and pleaded with him to escape and save his life. But in the Field Marshal's chest beat a brave heart. 'It is not right,' he cried, pushing away the reins being handed to him. 'Only a coward would flee from the field, where the empire has lost so many good men.' Then brave Menno Coehoorn said... [...]
And so the power of Nilfgaard lay in the dirt and dust of the fields of Brenna, and the march north by the Empire was laid to an end. The losses for the Empire amounted to forty thousand killed and captured men. The foundation of Elite Knights fell. They died in captivity or went missing without a trace like such as the leaders, Menno Coehoorn, Braibant, de Mellis-Stroke, van Lo, Tyrconnel, Eggebracht and others, whose names have not been preserved in our archives. Brenna was indeed the beginning of the end. But it is worth writing that this battle would have been a small stone in the building and its importance would have been small if the fruits of victory had not been used wisely. Contable John Natalis did not rest on his laurel, but immediately went to the south. An unexpected counterattack led by Adam Pangratt and Julia Abatemarco surprised two divisions of the Third Army which were running late to relieve Coehoorn, and were routed nec nuntius cladis. At this new the rest of the Center Group Army crossed shamefully back over the Yaruga and escaped in a hurry, and Foltest and Natalis followed on their heels. The Imperials lost their baggage train and all their siege engines which they planned to conquer Vizima, Gors Velen and Novigrad. Like an avalanche rolling down from the mountains into the valley that collect more and more snow and gains power, so did the consequences of the Battle of Brenna provide more damage to the Nilfgaardians. The Verden Group Army was heavily afflicted by the pirate raids and attacks from Skellige and King Ethain of Cidaris. When Commander Duke de Wett learned of the disaster at Brenna and the news reached him that Foltest and John Natalis had ordered a forced march, he immediately sounded a retreat and in panic fled across the river to Cintra and escaping significant losses to his troops, because word had gotten around about Nilfgaard's defeat and a new rebellion was rising in force in Verden. Only troops remained in the forts of Nastrog, Rozrog and Bodrog and after the Peace of Cintra they emerged with honour with banners aloft. Meanwhile in Aedirn, the news of what happened at Brenna caused the antagonised Kings Demavend and Henselt to join togheter in arms against Nilfgaard's East Group Army, which was led by Duke Ardal aep Dahy into the Pontar valley, unable to resist the combined forces of the two kings. With the addition of the strenght of the troops from Redania and the guerrilla squads of Queen Meve, who undertook combat actions in the rear of the enemy, they forced Nilfgaard to Aldersberg. Ardal aep Dahy prepared for battle, but due to fate he suddently become serious ill, perhaps from spoiled food he got colic and diarrhoea and two days later died in pain. Demavend and Henselt, without waiting, launched an attack against Nilfgaard in Aldersberg, surely because of historical justice, Nilfgaard suffered a heavy defeat, though they still had numerical superiorit. But daring, spirit and technique won out over blind, brute force. It is necessary to mention one other thing - namely that it is still unknown what happening at Brenne to Menno Coehoorn. Some believe that he fell with his soldier and his remains, unrecognised were laid to rest in a common grave. Others speculate that he escaped, but from fear of the Imperial wrath never returned to Nilfgaard, but instead resorted to the Dryads in Brokilon and become a hermit in the forest. In remorse he lived for years in seclusion and separation and eventually died. Among ordinary people circulated the rumour that the famous Marshal in the night after the battle returned to the field at Brenna and could not stand looking at the tragedy and hanged himself from a aspen on a hill, which from that time on was called Gallows. At night it is said that his spirit wanders the battle field, lamenting and crying out 'Give me back my legions!'.
