After the war, Bolton finished sixth in 1919–20. With the help of "Trotters" teammate Ted Vizard, during the 1920–21 season Smith scored a club record 38 goals, which put him top of the First Division goalscoring chart for that season; the club recorded a third-place finish. However Bolton dropped to sixth position again in 1921–22. Smith recorded 19 goals in 1922–23 to become the club's top-scorer for the fifth time. His goals helped Bolton to reach the 1923 FA Cup Final – the first FA Cup final to be held at Wembley. Smith captained Bolton to a 2–0 victory over West Ham United. David Jack then took the mantle as the club's main source of goals in 1923–24 and 1924–25, as Bolton posted two top four finishes in succession. Smith scored 21 goals in 1925–26 to finish as the club's top-scorer for the sixth and final time. He also captained the club to another FA Cup final victory, as a goal from namesake Jack Smith was enough to beat Manchester City 1–0. The 1926–27 season was then his last at the club, as he led Bolton to fourth in the league, eight points behind leaders Newcastle United. In his nineteen years with Bolton, Smith scored 277 goals in 492 games (his league record being 254 goals in 449 appearances).
