This document possibly a contemporary copy, is refering to Cromwell's illness during 1658 which proved fatal. Adjutant General Allen was present at the three days prayer meeting which took place at Windsor in April 1648, in which Cromwell took a leading part. The Army leaders reviewed their past political actions, and decided to call Charles Stuart to account for all the "mischief he had done". From then on Allen was most undecided in his opinions, and as will be seen from the above letter , he changed from thinking in 1654 that Cromwell had "much uprightheartedness to the Lord" to deciding in 1658 that only Cromwell's death would bring peace to the Country.
