The London Trained Bands (LTBs) were a part-time military force in the City of London from 1559 until they were reconstituted as conventional Militia regiments in 1794. They were periodically embodied for home defence, for example in the army mustered at Tilbury during the Armada Campaign of 1588. They saw a great deal of active service during the English Civil War, including the First and Second Battles of Newbury, and the battles of Alton, Cheriton, Cropredy Bridge and Lostwithiel. Throughout their history they were used to suppress civil disorder and insurrection around the capital.
