context_page_description: 91st Heavy Anti-Aircraft Regiment, Royal Artillery was a part-time unit of Britain's Territorial Army formed in the West Riding of Yorkshire just before the outbreak of World War II. Its service during the war included Home Defence during the Battle of Britain and The Blitz, and a length period in Middle East Forces. Postwar it continued to serve in the TA in the air defence role until 1955.
context_section_description: After the Fall of France, German day and night air raids and mine laying began along the East Coast of England, intensifying through June 1940. Several times the Humber HAA guns (62nd and 91st HAA Rgts) were in action against aircraft attacking the Salt End and North Killingholme oil installations, and the regiment claimed its first two 'kills' on the night of 26/27 June. It claimed another three by the middle of August.
  Luftwaffe night raids over the Humber increased during August while the Battle of Britain was under way, but were still small in scale. 221 HAA Battery was nominated as a reserve battery with mobile guns, and during September it was sent to reinforce 26 (London) AA Bde defending London as The Blitz got under way (where one gunner was killed by a bomb blast). In mid-October, 270 Bty and half of 286 HAA Bty (from Horsham St Faith) were sent by 39 AA Bde to reinforce the Sheffield Gun Zone under the command of 67th (York and Lancaster) HAA Rgt, while the other half of 286 Bty went to London to reinforce 221 Bty. 221 Battery moved from London to Norwich in October, and then to Nottingham and Derby in December. The CO, Lt-Col Chilman, went to command a training regiment in October and was replaced by Lt-Col K.W. MacKichan.
