The Mordor battle line:
Grishnakh’s raiders form the right of the line with a four company formation of orcs next to them. A troll forms the link between the two orc formations, followed by the troll drummer, artillery, archers with the Witch King in support, the formation of Morannon orcs and Gothmog with the six companies of warg riders on the left flank.
Boromir was going to have his work cut out against this host.
