XIII.
The booming salvo hurls its ceaseless shower,
Saint John’s huge bastion slowly crumbling falls,
Destruction seizes many a stately tower,
And totter to their base Tirynthian walls
Beneath the fury of resistless balls,
From circling orchards heaved by Britain’s sons;
And snake-like trench advancing swift appals
The garrison, as o’er the isthmus runs
The deadly sapper’s stroke that like an earthquake stuns.
