Wesley Eagen was the Confederation of North America's ambassador to New Granada in the late 1880s. He was presumably an important member of the People's Coalition who received the posting in 1888 after Ezra Gallivan became Governor-General of the C.N.A.
As war loomed between New Granada and the United States of Mexico in February 1890, Eagen was summoned to the offices of Premier Adolfo Camacho on the morning of the fifteenth, along with the ambassadors from Great Britain and Spain. Camacho informed Eagen and the others that the previous day, Mexican Chief of State Benito Hermión had ordered the Mexican army stationed in Guatemala to a state of readiness, and alerted elements of Mexico's Pacific and Gulf Fleets to prepare for action. Camacho then told Eagen and the others, "We will fight the Mexicans if it comes to that, but in our struggle we may need help. What will your countries do in this time of trouble?" Camacho then went on to warn Eagen specifically that "today Hermión threatens La Guaira, tomorrow he may attack Norfolk. You must realize that we will fight, and may be able to defeat this madman without your help. But if we fail, you will be next. Guatemala was the doorway to Bogotá, and Bogotá may prove the gateway to Burgoyne."
Eagen returned to the North American embassy and wired news of his meeting to Gallivan. The Governor-General indicated that while he sympathized with the plight of the New Granadans, he was not prepared to risk war with the U.S.M. to defend them. He ordered the Office of Foreign Affairs to inform Edmundo Roa, the Mexican ambassador to the C.N.A., of his "grave concern," but he did nothing else. The British and Spanish governments had been more willing to intervene, but would not do so without the North Americans. In the end, the New Granadans had to face the Mexicans alone.
Wesley Eagen does not have an entry in Sobel's index. He is mentioned on page 220 of For Want of a Nail ....
Sobel's source for Wesley Eagen's tenure as ambassador to New Granada is Eagen's memoir, In the Twilight (New York, 1909).
