Draco and Theo fought in unison as their bonds held the shields and then they swapped, giving themselves time to regain strength. The death eaters on either side of Voldemort - his closest most coveted members - fought alongside him but there were enough Order members and older students that they didn't get in the way. Ginny Weasley blasted Dawlish - a loathsome character Draco had always despised - so viciously that he tripped over his own cloak and exploded into a shower of fleshy chunks and splintering bones. The explosion took out several spiders that were using him as a human shield too.
