Jardine is best known for captaining the English team during the 1932–33 Ashes tour of Australia. There, his team used 'bodyline' tactics against Donald Bradman and other opposing Australian batsmen. A bodyline delivery was one where the cricket ball was pitched short so as to rise towards the body of the opposing batsman on the line of the leg stump. The plan was to get legside deflections that could be caught by one of several fielders on the leg side. This tactic was considered by many to be intimidatory and physically threatening. Jardine is widely regarded by commentators and writers as the person responsible for that strategy.
