Bertie won recognition for unsuccessfully defending his ship against superior odds in the American Revolutionary War. He was later criticised however for failing to close with the enemy at the Glorious First of June and later for pulling rank on a subordinate officer just days before the capture of the French island of Mauritius and taking credit for the victory. Despite these controversies, Bertie was rewarded for his service with a baronetcy and the Order of the Bath, retiring in 1813 to his country estate at Donnington, Berkshire.
