Look, what I speak, my life shall prove it true;
That Mowbray hath received eight thousand nobles
In name of lendings for your highness' soldiers,
The which he hath detain'd for lewd employments,
Like a false traitor and injurious villain.
Besides I say and will in battle prove,
Or here or elsewhere to the furthest verge
That ever was survey'd by English eye,
That all the treasons for these eighteen years
Complotted and contrived in this land
Fetch from false Mowbray their first head and spring.
Further I say and further will maintain
Upon his bad life to make all this good,
That he did plot the Duke of Gloucester's death,
Suggest his soon-believing adversaries,
And consequently, like a traitor coward,
Sluiced out his innocent soul through streams of blood:
Which blood, like sacrificing Abel's, cries,
Even from the tongueless caverns of the earth,
To me for justice and rough chastisement;
And, by the glorious worth of my descent,
This arm shall do it, or this life be spent.
