In the eight seasons after the Second World War Gimblett was the mainstay of the Somerset batting. Without taming his aggressive instincts, he had become more judicious in his shot selection, and though he remained until the end of his career likely to smash the first ball of a match for six, he also took on the role of senior batsman in a Somerset side that was usually weak in batting. In the 1946 season, Somerset's best for more than 50 years, he made 1947 runs at an average of 49.92 runs per innings, the highest seasonal average of his career. There were seven centuries, the most of any season, and they included 231 against Middlesex at Taunton, his first double century and part of what Wisden termed a "merciless onslaught" by the Somerset batsmen.
