"Not this time", Gandalf corrected the ElvenKing. "Armies of Orcs are on the move. They're bred-fighters; prepared for war. Our enemy summoned his full strength because we forced him, ever since the company of Thorin Oakenshield had set out to reclaim their homeland", he explained before proceeding to walk out the tent, and look towards the sealed entrance to Erebor, in the distance. "They were never meant to reach the Mountain; Azog the Defiler was sent to kill them", he paused right there, knowing that it was Saeril who sent the Orc there, while under Sauron's control. 

"His master, whom they call "the One", seeks control of the Mountain; not just for the treasure within, but for where it lies; its strategic position", he glanced back to Bard and Thranduil. "It's a gateway to reclaim the lands of Angmar in the North. If that fell-Kingdom should rise again, Rivendell, Lórien, the Shire, even Gondor itself will fall".

Just as a swarm of bats flew before them, Legolas instinctively put an arm around Yavanna's shoulders, merely to shield her from the threat, while ducking in further himself. The blonde prince looked up to see the bats, just after Tauriel mentioned them. "These bats were bred for one purpose", he observed. "For war", his conclusion rang true just when he took notice upon Bolg summoning the rest of the Orc forces, along with the swarm. "We have to go back; warn the others. Come", he instructed them before taking his leave, holding the younger she-elf's hand, as he led the way back down the hill.
