Also during this time, the city's infrastructure underwent great improvements, with underground sewerage systems, paved streets and gas-powered street lighting.[18] An infantry regiment of the British Army was formed at Lichfield in 1705 by Col. Luke Lillingstone in the King's Head tavern in Bird Street. In 1751 it became the 38th Regiment of Foot, and in 1783 the 1st Staffordshire Regiment; after reorganisation in 1881 it became the 1st battalion of the South Staffordshire Regiment.[17]
