" `Tis thus that, through the greedy servant's sin,

  And easy sovereign's goodness, on his side,

  The files beneath his banners muster thin,

  When in his midnight camp, `to arms,' is cried,

  For by the wary Spaniards charged within

  His ramparts is he; foes that with the guide

  Of Avalo's fair lineage, would assay

  To make to heaven or hell their desperate way.
