In Greece, his services were not confined to the duties of a surgeon but were of a more military nature. Howe's bravery, enthusiasm, and ability as a commander, as well as his humanity, won him the title "the Lafayette of the Greek Revolution." Howe returned to the United States in 1827, to raise funds and supplies to help alleviate the famine and suffering in Greece. Howe's fervid appeals enabled him to collect about $60,000 which he spent on provisions, clothing, and the establishment of a relief depot for refugees near Aegina. He later formed another colony for exiles on the Isthmus of Corinth. Afterwards, Howe wrote an account of the revolt, "Historical Sketch of the Greek Revolution", which was published in 1828.
