Solemn Engagement

The Solemn Engagement (A Solemne Engagement of the Army, under the Command of his Excellency Sir Thomas Fairfax) was a declaration to the English House of Commons adopted unanimously by the General Council of the Army commanded by Thomas Fairfax at Newmarket on May 29, 1647. Acting in response to a parliamentary threat of disbandment, the document asserted that the army would not disband until satisfactory terms were negotiated. This was in part because of weeks of arrears owed to the soldiers, and in frustration of the slow progress parliament had made in securing a settlement with the imprisoned Charles I.
