Lichfield's position as a focus of supply routes had an important strategic significance during the war, and both forces were anxious for control of the city. The Parliamentary commander Lord Brooke led an assault on the fortified close, but was killed by a deflected bullet on St Chad's day in 1643, an accident welcomed as a miracle by the Royalists. The close subsequently yielded to the Parliamentarians, but was retaken by Prince Rupert of the Rhine in the same year; on the collapse of the Royalist cause in 1646 it again surrendered.
