Question: When did the first commanding officer of the 6th Airlanding Brigade join the military? Passage 1:In 1908, the New York State Legislature created a statewide system of unsigned legislative routes. The portion of what is now NY34 from Van Etten to Ithaca was included in Route9, which originally began in Horseheads and went generally northeast across central New York to Bouckville. North of Ithaca, two sections of modern NY34from Cayuga Heights Road north to current NY34B in Lansing and from the north end of NY34B in Fleming to Auburnbecame part of Route11. On March1, 1921, Route9 was realigned south of Van Etten to follow modern NY34 south to Chemung Street in Waverly. When the first set of posted routes in New York were assigned in 1924, none of modern NY34 received a signed designation except for the current overlap between NY34 and NY13 south of Ithaca, which became NY13 at this time.
Passage 2:On 23April1943, the War Office gave permission to raise a second airborne division, the 6th Airborne. The division comprised the 3rd and 5th Parachute Brigades and the 6th Airlanding Brigade, giving it two parachute and one airlanding brigades, which became the standard British complement for an airborne division. In May 1943 Brigadier Hugh Kindersley was appointed as the airlanding brigade's first Commanding Officer (CO). Under his command he had two experienced battalions transferred from the 1st Airlanding Brigade: the 2nd Battalion, Oxfordshire and Buckinghamshire Light Infantry (2nd OBLI) and the 1st Battalion, Royal Ulster Rifles (1st RUR). They were joined by a unit newly transferred to the airborne forces, the 12th Battalion, Devonshire Regiment (12th Devons), a hostilities-only unit formed during the war, as the brigade's third infantry battalion. Other units assigned around the same time were the 53rd (Worcestershire Yeomanry) Airlanding Light Regiment, Royal Artillery, the 249th (Airborne) Field Company, Royal Engineers and the 195th (Airlanding) Field Ambulance, Royal Army Medical Corps.
Passage 3:Close to the West Pennine Moors, Bolton is northwest of Manchester. It is surrounded by several smaller towns and villages that together form the Metropolitan Borough of Bolton, of which Bolton is the administrative centre. The town of Bolton has a population of 139,403, whilst the wider metropolitan borough has a population of 262,400. Historically part of Lancashire, Bolton originated as a small settlement in the moorland known as Bolton le Moors. In the English Civil War, the town was a Parliamentarian outpost in a staunchly Royalist region, and as a result was stormed by 3,000Royalist troops led by Prince Rupert of the Rhine in 1644. In what became known as the Bolton Massacre, 1,600residents were killed and 700 were taken prisoner.
