Gandalf played a crucial role. It was Gandalf who warned the Elves, Men, and Dwarves of the incoming Goblins. It was also Gandalf who arranged for the Eagles to come. Without the Eagles, the battle surely would have been lost. The Eagles role was important as they freed the ledges of the Goblins, enabling all defenders to head to the gate. And also, it is speculated that Gandalf had something to do with Beorn's appearance, since he was in direct contact earlier. Beorn's swift coming and going was what won the battle.
The battle of the five armies in "The Hobbit" starts when Thorin Oakenshield refuses to share the treasure with the other armies and a battle ensues over the mountain.

Bilbo plays no part in the Battle of Five Armies. He took his stand with the elves and put on his ring. But he got knocked out by a stone and missed it all.
In "The Hobbit," the eagles play a crucial role during the Battle of the Five Armies by arriving at a pivotal moment to aid the forces of good. Led by the Great Eagle, they swoop down to assist Thorin Oakenshield and his allies, helping to turn the tide against the goblin and warg forces. Their timely intervention not only saves lives but also symbolizes the theme of unexpected allies coming together in times of need. Ultimately, the eagles' bravery and strength are instrumental in achieving victory in the battle.
The hobbits were trapped on the edge of a cliff in a tree and the Orcs were surrounding them. The eagles flew in and saved them.
