Crusades according to Shakespeare

"As far as to the sepulchre of Christ--
Whose soldier now, under whose blessed cross
We are impressed and engaged to fight--"...

But I have sent for him to answer this;

And for this cause awhile we must neglect
Our holy purpose to Jerusalem....
But come yourself with speed to us again;
For more is to be said and to be done

Than out of anger can be uttered.

WESTMORELAND I will, my liege.
