It was the proud privilege of both the Prince brothers to give their active services to France on the battle fronts. Having passed their boyhood and early youth together, performing the same tasks and enjoying the same recreations, Frederick and Norman developed similar ambitions and aptitudes, particularly in their more strenuous activities. Moreover, they had obtained in part their early education in France, and the call to the French colors at the outbreak of the war appealed almost as strongly to them as to the patriotic Frenchmen. Norman’s early experience as an aviator at home and abroad gave him a temporary advantage over Frederick in that he already had the preliminary training for service in the aviation corps in which both desired to enlist. He was consequently first of the two to realize his heart’s desire and to take the oath of allegiance to France and her cause. It was with pardonable hesitation that permission was subsequently given by his parents to their only other son to join Norman in the perilous aviation service but it was freely given, with an appeal for God’s blessing, and Frederick sailed for France with Norman on the latter’s return from his Christmas furlough at home in 1915. He underwent the rigorous training at the Pau aviation school and began his active service at the front in the late summer, flying at first with the intrepid Captain Guynemer, at the latter’s invitation, and subsequently joining the Lafayette Squadron on the western front. He won the high esteem of his comrades for his courage and manly bearing, performing his duty with joyous enthusiasm and taking active part in twenty-two aerial engagements during the ensuing five months. When Norman fell at Luxeuil, it was a trying moment to Frederick, who had lost his only brother and the companion of his lifetime, but he promptly offered his services to France in his brother’s place and he fought with the Lafayette Escadrille until he came home on a short furlough. He subsequently returned to France to rejoin his Squadron with courage undaunted, and with unflagging faith in the ultimate triumph of the cause he loved and for which he was proud to be actively enlisted.
