Monk had now time to breathe. On the 20th the post was allowed to go,
and with it went three official letters from the general. One was to
the Speaker, laconically informing him that the Scotch army was at the
service of the Parliament if it were still under restraint, and that
in accordance with his new commission he had cashiered such officers
as would not recognise its authority. "I do call God to witness," he
concluded, "that the asserting of a Commonwealth is the only intent of
my heart, and I desire if possible to avoid the shedding of blood, and
therefore entreat you that there may be a good understanding between
Parliament and army. But if they will not obey your commands I will not
desert you according to my duty and promise."
