Boyd began his education at
Punahou School, known as Oahu College at the time. In 1880, King Kalākaua established a
government-funded program for promising Hawaiian youths to be educated abroad. Boyd;
James Kaneholo Booth, his Punahou classmate; and
Robert William Wilcox, a Maui-born schoolteacher in Honolulu, were chosen as the first students of the Hawaiian study abroad program. They were sent to Europe along with
Celso Caesar Moreno, a former cabinet minister who had been controversially dismissed. Kalākaua intended for them to be sent to
Prussian military academies; however, once in Prussia, Moreno decided they were unsuited for the rigors of the Prussian schooling system. The three Hawaiian youths were enrolled in different military academies in Moreno's native Italy instead. Wilcox and Booth were enrolled at the
Royal Military Academy in
Turin and
Royal Military Academy in
Naples, respectively, while Boyd was enrolled in the
Royal Naval Academy at
Livorno. During
Kalākaua's 1881 world tour, the king and his entourage were greeted by Moreno, Booth, and Boyd at the Naples pier. Later, in an audience with
Umberto I of Italy and his wife
Margherita of Savoy, they learned that Moreno had misrepresented the three students as Kalākaua's natural (i.e., illegitimate) sons. After this revelation, Moreno was dismissed as the guardian of the three students and
Michael Cerulli, who later became Hawaiian consul-general in Naples, was appointed to take care of their needs. The frugal spending allowance given to the youths was often only enough for their basic necessities. Boyd often wrote home to
Walter Murray Gibson, the king's prime minister, to ask for additional funds. Encouraged by Moreno, they sought the same lifestyle as their more affluent Italian classmates who were able to travel during school holidays. In 1884, Boyd's failure to pass his final exam greatly distressed him. In a letter dated March 27, 1884, he wrote home to the king, informing him about his failure to pass his exams and begging him to allow him return to the islands: Now Your Majesty must know the truth, and nothing else but the truth, I am five years abroad, and during this short period I have suffered more than a man of forty; I have had vengance, I have had a duel, and lastly I have had enemies: all for the sake of my country. Their has[sic] been times in which I wished to runaway and beg for my living, but when I think of your kindness towards me, my passion calms quickly, and I dream of the happy future: But at last I have come to the conclusion not to suffer anymore, my studies to the present are not at all little; and perhaps sufficient to earn my living as a gentleman; Theirfore I am ready to come home and serve thee Sire, or else I shall run away because I would rather die a beggar than to be a slave. I will take a square resolution as soon as I receive Your Majesty's letter; but I swear in the name of my dead father that I will stay no longer in this revengeful country. The schooling ends on the 3rd of June, and I should wait for your answer in August, if at the end of this month I receive no answer, Your Majesty may calculate that I have no Country, I have no parents, and I have no king; I will be a roamer all the days of my life, like a Jew: I will come back to serve you as a souldier, and even as a shoeblacker; but I will never be a slave. Your Majesty may be sure that these words are as true as If I had my hands on the bible while writtin it, theirfore give me hope, and let me die in peace: I will repeat again, that my education is quite sufficient. I can come home alone, not as a child, but as a young man of 21 years old. I have the honor to wish his Majesty a prosperous reign and a long life. Despite these setbacks, Boyd continued in his education until the summer of 1887. After passing his final examinations in June, Boyd reunited with his brother Colonel James Harbottle Boyd and attended the
Golden Jubilee of Queen Victoria with the Hawaiian delegation led by
Queen Kapiolani and Crown Princess Liliuokalani. While in London, Colonel Boyd wrote to the Hawaiian government about the future for his brother. However, news of political unrest back home prompted the Hawaiian royal party to return to the islands in July. Boyd stayed behind in
Liverpool until he also returned to Hawaii on October 22, 1887, aboard the steamer
Adriatic. ==Return to Hawaii and the Wilcox rebellion==
