Cawthorne supported North; voted against Shelburne’s peace preliminaries, 18 Feb. 1783, for Fox’s India bill, and against Pitt’s Government; and after the general election of 1784 was listed by William Adam with Opposition. But when in the new House Delaval declared his adherence to Pitt, Cawthorne again followed him; defended Delaval when attacked by Philip Francis for changing sides, 16 July 1784;
Cawthorne died 1 Mar. 1831.
