In 1892, when Churchill was 17, he won the Public Schools fencing championship, presaging his future career as a fighting man. Generally, however, his other achievements at school didn’t seem to suggest an academic future. His parents decided that he wasn’t university material and instead they wanted him to try to enter the Royal Military College at Sandhurst and the military career for which he had already shown an inclination.
He left Harrow in 1892 and went to a ‘crammer’ to help him pass the entrance exam, which he eventually did on the third attempt in 1893. Churchill’s poor maths meant he couldn’t join the artillery and engineers, and he didn’t do well enough in the final exam to qualify for the infantry, much to his father’s disappointment. Against his father’s wishes, he qualified for a cavalry cadetship (the cavalry was more expensive than the infantry; the family would need to buy one or two costly ‘hunters’, polo ponies).
