The Host of the West marches from Minas Tirith. Frodo comes in sight of the Insenmouthe; he is overtaken by Orcs on the road from Durthang to Udun.
It had been three days now since Thranduil and his people had prevented the evil that grew in the forest from gaining a bigger foothold. He wished they had been able to do something about it sooner, yet they had lost too many trying and he was now in mourning for a good many more.
And yet it was still not done. They had merely repelled the forces there, not destroyed them for good. Now they had to regroup and find a way to do the deed, for the evil could not be allowed to lurk here for much longer.
