XVI.
“Their light arm’d archers far and near
Survey’d the tangled ground;
Their center ranks, with pike and spear,
A twilight forest frown’d;
Their barbed[349] horsemen, in the rear,
The stern battalia[350] crown’d.
No cymbal clash’d, no clarion rang,
Still were the pipe and drum;
Save heavy tread, and armor’s clang,
The sullen march was dumb.
There breathed no wind their crests to shake,
Or wave their flags abroad;
Scarce the frail aspen seem’d to quake,
That shadow’d o’er their road.
Their vaward[351] scouts no tidings bring,
Can rouse no lurking foe,
Nor spy a trace of living thing,
Save when they stirr’d the roe;
The host moves like a deep-sea wave,
Where rise no rocks its pride to brave,
High swelling, dark, and slow.
The lake is pass’d, and now they gain
A narrow and a broken plain,
Before the Trosachs’ rugged jaws;
And here the horse and spearmen pause.
While, to explore the dangerous glen,
Dive through the pass the archer men.”
