Private Quelch, merely another soldier in the platoon, who believed not so of himself; also significantly discovered to be a student, he was called 'The Professor' by his partners. Quelch's understanding was not more than extraordinary; nevertheless, his qualities were under shadowed by his haughtiness. Himself was open in when he wanted for consent and usually broke and not required. He was one guy who patronised himself and fancied his own whims. Knowledge, though he had, Quelch didn't possess etiquette. Like somebody who came un-invited, The Professor would exhibit his understanding from time to time, in front of his mates, juniors, seniors. He considered himself to be respected for his learning and his trust, yet, his seniors cared little for him. Doom was brought by him by trifling with Corporal Turnbull who assigned long-lasting cookhouse duties to Quelch to educate a lesson to him. However, The Professor had some thing to be respected for, his firm approach. Himself was still essential and condescending of individuals around him.
