I personally prefer to watch magic movies, and the Hobbit series has been brushed many times, and the most enjoyable of this series is the battle scenes, especially the battle of the Five Armies: the Iron Hill Dwarven Army (Dwarven Tribe), the Long Lake Human Army (Human), the Jungle Elf Army (Elf Clan), the Misty Mountain Orc Army (Half Orc), and the Gombado Orc Army (Seat Wolf). The dwarves and elves have always been at odds, but in this war, the dwarves showed a heroic posture, and the proud elves hid behind the dwarves, and they reached an alliance with humans, temporarily putting aside their prejudices against each other, and joining forces against a large number of half-orcs and wolves.

Elves
The most exciting scene is that the human race shouts as it charges: For honor, rest until death. The whole picture of the battle is shocking. The following is a description of this war with less victory over more.
Humans and elves
Thorin and the others were thus surrounded by men led by the elven kings Thranduil and Bud. Thorin used the Ravens of Lonely Hill to ask for help from the dwarves of the Iron Hills, whose ruler Dane II led more than 500 heavily armored dwarven warriors to Lonely Hill in solidarity with Thorin, most of whom had participated in the war between the dwarves and the half-orcs. Dane II's army arrived and nearly war broke out, but Gandalf at this point declared that the misty mountains and the half-orcs of Eredmyn were attacking them under the leadership of Chief Bog. When the half-orcs learned of Smaug's death, they immediately mobilized their entire army to attack the unguarded treasure house.
The commanders of the three armies agreed that the half-orcs were their common enemy and could pose a greater threat to them, so they put aside the dispute for the time being. They placed their armies on ridges on either side of a canyon that was the only way into the LoneLy Mountain. The Dwarves and the Humans of Long Lake were ambushed on one ridge, while the Elven army was ambushed on another. They also deployed a small number of troops at the mouth of the valley to lure the enemy army deep into the valley. Bilbo Baggins was in the elven army and did not participate in the war.
Seat Wolf Clan
An army of half-orcs and wolves arrives, and the dwarves, elves, and humans allied their strategy initially comes to fruition. The army of half-orcs and wolves was lured into the valley by a small number of Long Lake warriors and suffered heavy losses, but due to the large number of enemy troops, the combined forces of dwarves, elves and humans were unable to prevail. The half-orcs began to climb the hill on the back, pinching the coalition forces on the ridge. The war broke out in full swing, and Thorin and others in the mountains also heard the loud noise of war, and they knocked down the stone wall on the gate and killed many half-orcs. Thorin and the others received the best weapons and equipment from the treasure house and began to join the battle group. Thorin burst into the half-orc army, but was blocked by Bog's giant guards and surrounded.
The coalition forces were caught in a bitter battle, and the leader of the giant eagles in the Misty Mountains led the giant eagles to reinforcements. Bilbo first spotted the eagle and shouted "Here comes the eagle," provoking a half-orc to stun Bilbo with a stone. The giant eagle crushed the enemy forces on the mountain, allowing the coalition forces to concentrate on the battle in the valley and gradually regain the advantage. Behon now appears on the battlefield in the form of a bear, and Behon breaks the half-orc defenses, carrying the wounded Thorin, who, in a fit of rage, breaks up Bog's guards and kills Pog. The half-orcs were defeated, and the coalition forces took advantage of the victory to pursue and win.
