Wyniel had seen the orcs. She hadn't recognized them, rather seeing the few black shapes appear where there was only grey rock before. Her eyes popped and her heart raced, hearing the bowstrings snap and the arrows whistle. Finally she recognized the azure sky, speckled with gathering clouds, and heard the sound of horse's feet.
Boromir turned when he heard the arrows. He saw his wife stumble and fall heavily backward, her dress billowing strangely in front of her as she did so. He sprinted quickly to her side, glimpsing the black shapes across the river. He was confused and frightened when he saw the arrows, but not his wife, lifting up and down through the grass.
His decorated shield he rested at Wyniel's feet when he found her. She was pierced three times in the chest.
