You launch your bolts, finding easy shots on the left and right sides of the knight's relatively unprotected neck- two shots which take him down instantly.
Bolts and arrows fly across the valley, pure shots ringing clear in painful squelches and shots off-target ringing with a clear steel tone, muffled by padding underneath the heavy plates. One of the charging knights is held up with your pit traps, while the other takes the hint and watches out for the pits and deftly avoids them- he's still slowed down from the hail of javelins coming towards him, though. A great hail of arrows keeps the third back, immobilized.
(Round 2)
You launch another bolt, the first taking down the nearest rider, and the next going towards the next nearest rider, missing the gap between his pauldron and breastplate by just a hair, leaving a dent in the border metal.
As you watch, the two riders' horses and bodies begin to smolder and combust, the armor and their bodies turning quickly to ash to be blown away in the wind.
More fire comes from your men, bolts piercing the plate of the remaining riders. The near rider gets back up again and begins another charge, only to fall to another pit trap you set up.
Bolts fly in, bloodying the knight and both your squads pick up arms to attack the downed knight. The squad of archers keeps the last knight pinned down throughout the combat.
(Round 3)
Your first shot- breathe, hold, pull. A bolt flies through the downed rider's breastplate- a flaw in the metal you managed to see, probably a point repaired many battles ago. Blood spews forth, and the rider's last breath flows from his lungs. You refocus, aiming towards the pinned-down rider. Your bolt flies true, pinning the easy spot between the shoulder plate and the main segment of his heavy armor, a bloody and painful wound.
More bolts fly towards him, and he seems very weakened. Your archers ready a final volley, and as the first shots barely impact he falls over, dying on the ground. Arrows penetrate the weak points in his armor, finishing him off finally. The final riders' horse and body wither off into red embers that fly away on an unseen breeze. Scrambles from the rubble you set off cease, and you see flares smoking from beneath the rocks.
The battle is over; the reinforcements stopped. Your ground troops gather the greatswords wielded by the knights, and you bark an order down to salvage anything from the dragon that they can- they manage to cut off several stony scales which seem rather light to you, and a couple vials of the beast's molten blood. Anything else is certainly beyond their grasp. You head back to your field camp, forces in tow.
((Sorry for taking so long, same deal here with school in the way. Spring break now, though.))
