Input: Question: How many months after the beginning of World War II was Kershaw commissioned as a second lieutenant? Passage:At the beginning of World War II, Kershaw served with the Thames River police, then was commissioned second lieutenant in the 16th/5th Lancers on 15 June 1940. He was promoted temporary captain, and landed in North Africa in November 1942 in Operation Torch. He served in tanks, and was awarded the Military Cross (MC) for his actions north of the Kasserine Gap in Tunisia in 1943. On 21 February 1943 he was a brigade staff officer (GSO3) with 26th Armoured Brigade (which comprised his own regiment amongst others) and had command of the brigade command tank. The brigadier was commanding from a scout car whose radio broke down. Kershaw, despite heavy machine gun and artillery fire, repeatedly ran from his tank, to the scout car, and back, to take the brigadier's orders, which he then relayed over the tank's radio. The following day, a German counterattack was believed to be imminent. Kershaw volunteered to man his tank, which had been disabled, to bring additional fire to bear on the advancing forces; despite its vulnerability to artillery fire as it was in full view on a road.
