The orcs are not so clever if i was the general i would devide them in lines, when the troops of rohan arrived the whole tactic was wrong, i would brought large shields with many large points on them to cover the rear end. The spearmen must run towards them, they were scared the orcs, and where are there reinforcements, the big giants they could wipe out the riders of rohan! And the fighting spirits i thought it was a dissapointment, i wanted to see a true battle, the elephants had been used earlier when they galloped at the troops of the orcs, where were the URUK'HAI??? I know its written in the novel but like braveheart the orcs had could defeated the riders of rohan!!!!
