Read it through once

"Sir,--Your majesty may think it the misfortune I now lie under makes me make this application to you; but I do assure your majesty, it is the remorse I now have in me of the wrong I have done you in several things, and now in taking up arms against you. For my taking up arms, it was never in my thought since the king died: the Prince and Princess of Orange will be witness for me of the assurance I gave them, that I would never stir against you. But my misfortune was such as to meet with some horrid people, that made me believe things of your majesty, and gave me so many false arguments, that I was fully led away to believe that it was a shame and a sin before God not to do it. But, sir, I will not trouble your majesty at present with many things I could say for myself, that I am sure would move your compassion; the chief end of this letter being only to beg of you, that I may have that happiness as to speak to your majesty; for I have that to say to you, sir, that I hope may give you a long and happy reign.
