I think The eagle's were an army. They played an important part in the battle. They were active in it.
Seeing the sudden gleam in the gloom
Bilbo looked round. He gave a great cry:
he had seen a sight that made his heart leap, dark shapes small yet majestic
against the distant glow.
“The
Eagles! The Eagles!” he shouted. “The Eagles are coming!”
Bilbo’s eyes were seldom wrong. The eagles were coming down the wind,
line after line, in such a host as must have gathered from all the eyries of
the North.
So the host was gathered from all the eyeries of north. i doubt if it would have been 10!
That, however, was a little
delayed, so in the meantime I will tell something of
events. The Eagles had
long had suspicion of the
goblins’ mustering; from their watchfulness the
movements in the
mountains could not be altogether hid. So they too had
gathered in great numbers, under the
great Eagle of the
Misty Mountains; and
at length smelling battle from afar they had come speeding down the gale in
the nick of time. They it was who dislodged the goblins from the mountainslopes,
casting them over precipices, or driving them down shrieking and
bewildered among their foes. It was not long before they had freed the Lonely
Mountain, and
elves and
men on either side of the valley could come at last to
the help of the battle below.
so this shows that they took an important part in the battle. they dislodged the goblins from the rear and the mountain slope or else the allies would have been defeated.
I dont think bilbo was an army. (LMAO)
Beorn? Well i dont think that should be considered an Army. For he was a man, even if a shape shifter and represented the line of men.
And he was alone.
In that last hour Beorn himself had appeared - no one knew how or from
where. He came alone, and in bear’s shape; and he seemed to have grown almost
to giant-size in his wrath. The roar of his voice was like drums and guns; and
he tossed
wolves and goblins
