The Siege of Chester occurred over a 16 month period between September 1644 and February 1646 during the First English Civil War.
In the engagement, Sir William Brereton and the Parliamentarians were ultimately successful in taking possession of the city and Royalist garrison commanded by Lord Byron.

Although the siege spanned nearly one and a half years, the degree to which the city was confined varied in intensity.
Throughout the 16 month time period, conflicts continued to occur between the Royalists and the Parliamentarians in Cheshire and during the spring and summer of 1645, the Royalists were successful in causing the parliamentarians to temporarily lift the siege.
Ultimately, however, the Parliamentarians enforced a total blockade and captured the city.
