Owing money to army agents he returned to England to face charges brought against him. He returned in 1810 and took government contracts to build infrastructure. This included gaols, schools and most memorable was in 1814 when commissioned to build a road through the blue Mountains with the aid of thirty convicts whose reward was their freedom. Cf.
