Samuel entered the navy in 1705 as a volunteer on board
HMS Ipswich, with Captain Kirktowne, and served in a subordinate rank and afterwards as a lieutenant through the
War of the Spanish Succession. On 12 January 1719 was appointed first lieutenant of
HMS Preston with Captain Robert Johnson. Both Goodere and Johnson transferred to
HMS Weymouth on 28 February 1719, and saw service in operations on the north coast of Spain in mid-1719. Later that year, on 6 November 1719, again with Johnson, he transferred to
HMS Deptford. A few weeks later, however, Johnson preferred a charge of misconduct against Goodere, alleging that an attack on
San Sebastián on 23 June had failed as a consequence of Goodere's actions. Goodere was tried by court-martial on 24 December 1719, was found guilty of "having been very much wanting in the performance of his duty", and was dismissed from his ship, which, in time of peace, was equivalent to being dismissed from the service. In the opinion of
John Knox Laughton, it is doubtful whether Goodere served again at sea until November 1733, when he was posted to
HMS Antelope for a brief period of two weeks "apparently on some electioneering job" rather than as an active officer. He may have been living with his father, now nearing 80, who was on bad terms with his eldest surviving son, John. John was described as "rough, uncouth, and of no education". Samuel was also on bad terms with his brother; and these became worse when John, who had divorced his wife for adultery, found that she too was supported against him by Samuel. On the death of their father Sir Edward Goodere on 29 March 1739, John inherited the
baronetcy, but a share of the Goodere estate was left to Samuel. John thought Samuel's share was too generous, while Samuel thought it too little. The brothers quarrelled, and John, joining with his son who was of age, cut off the entail (bequest). Shortly after, his son died, and John announced his intention of leaving the property to one of the sons of his sister Eleanor, the mother of
Samuel Foote the comedian. == Murders his brother ==
