Any sketch of Edward Chapin which omitted to notice his religious character would be essentially incomplete. He early became a professed disciple of Christ, and to the end of his life he proved the genuineness and sincerity of his belief by his consistent Christian walk and conversation. In the hour of death his faith and hope did not fail him. A friend, writing of his last hours, says:—
He met death, not only with entire resignation, but apparently with triumph. A few hours before his departure he engaged in audible prayer, which was listened to with deep emotion by the hospital attendants and the wounded men about him. He prayed for the surgeons of the hospital, for the nurses, for the sick and suffering men, for the soldiers in the army, for his country that it might be delivered from its dangers, and for himself that he might be fully prepared for the change before him.In person he was of medium height, strongly built, with broad shoulders and full chest. His features were regular; his hair and eyes were light; his mouth well shaped, with his lips firmly shutting; his whole face indicating a firm and resolute character. Chapin was modest and unassuming in his manners, and perhaps somewhat reserved in his demeanor towards strangers, but thoroughly manly and independent in spirit. He usually held a high rank in his Class, whether in College or at the Academy; but he was a careful and thorough scholar, rather than a showy one. As a soldier he was resolute, patient, and faithful; thoroughly convinced of the justice of the cause for which he fought, and unwavering in his confidence in its success.
