Is this paragraph worded in the correct way?

Over the next few days, the orc horde repeatedly attacked the caravan, but they could not overcome the magical defenses created by the wizards in the convoy and were repulsed. One night while the caravan was encamped at the edge of the Chondalwood, the orcs managed to breach the defenses and the Shadovar directly assailed Kleef and his companions. The group fought valiantly against the shades, but they were forced to flee into the Chondalwood, where they were given assistance by the satyrs and treants living in the forest. While many of the forest creatures fought the orc warriors who attempted to pursue the four companions into the Chondalwood, one of the satyrs helped the group magically travel a great distance through the vast woods.
