Kili was right - Orcs fight very poorly without leadership. The cavalry line was broken, confused, and leaderless. The Orcs had lost focus on their mission. They had, unfortunately, turned their attention to her. The Orcs in front noticed her now, standing apart from the others with that Elf bow. Rhavaniel spun Warg around and raced across the open field. She turned in the saddle and began to shoot at Orcs behind her in rapid succession. A dozen Orcs broke free of the confused group and pursued her, enraged at having been infiltrated and duped. She and Warg ran to their fallback, behind a series of boulders.
Rhavaniel and Warg hunkered down, and she pulled off all the Orc fabric on Warg, revealing his Dwarf and Elf banners.
"Sit!" she told him. Rhavaniel tossed off her Orc cloak and hood to move more freely. She emptied her quiver of arrows at the approaching line of Orcs, and then pulled more arrows out from behind the rocks.
More mounted Orcs approached her - more even than she could shoot. She paused and crouched down behind a boulder, waiting for them to get closer. Just as the line was about to leap over her low stone defenses, she pulled back her camouflage tent. Too late, the Orcs and Wargs were impaled on the spikes she had buried in the ground last night. She finished the survivors off quickly with her sword. The display discouraged the second line of attackers, and she was able to once more her bow to pick them off. The field in front of her began to fill with fighting Men and Orcs.
It appeared to be mostly Man on her side of the battle. Rhavaniel was relieved. She was still afraid of her kinsmen, and she had heard that Dwarves could become so enraged in battle that they lost all sense of reason. A Dwarf in such a state might not recognize Warg's banner and leave him be. Rhavaniel tried to wipe some of the gray paint from her face. She no longer wanted to be mistaken for a little snaga Orc.
She kept using her arrows with perfect aim. She thought that the tide was turning in favor of Bard. She was wrong. A wave of goblins came over the foothills. They swarmed like ants along the side of the foothills that defended her. She shot her arrows without pause, on pure instinct. Even then, she would have been overcome if Warg had not reared up and began snapping away at the closest ones. The goblins left her alone and swarmed the field. It was heartbreaking to see men die so close, with nothing she could do. Men would fall under a mass of goblins. She could kill them - one, two, three, and four and as the Goblin bodies fell away she could see that the man beneath was already dead.
Rhavaniel glanced at her supplies. Over two hundred arrows gone. She pulled two hundred more from hiding and continued to fire, trying to pick which men she could still save. If a man had more than three goblins on him already, may Ilúvatar forgive her, she passed him by and aimed to help a man with better odds.
