Harry A. Hargreaves served as a 42-year-old Regimental Sergeant-Major in the 1st Connecticut Infantry when they were sent to Nogales, Arizona, three and a half months after Pancho Villa's raid on Columbus, New Mexico, in 1916. After six weeks at Camp Steven Little in Nogales, the regiment marched to Fort Huachuca for ten days, and then marched back to Nogales. They saw no active duty during that time.
Harry was born Aug. 24, 1877, in Philadelphia, Pa. His father died several years later, and his mother Mary remarried c. 1890. She had two children by her second husband, Norman R. Dean, who were Emily P. Dean (b. 1892) and Georgiana F. Dean (b. 1894). Harry was married ca. 1906. His wife Harriette H., seven years his junior, started an interior decorating company shortly after their marriage when the couple settled in New Britain, CT. They had no children. Harry, who was a dry goods salesman before his marriage, became a bookkeeper, and then by 1913 was serving as deputy city clerk of New Britain, an office he continued to hold into the 1920's. With his wife's income from her interior decorating business, they were well enough off in 1920 to employ a live-in chauffeur. Harry continued to be involved with the military after returning from his 1916 service with Pershing's Punitive Expedition, moving from Regimental Sergeant Major in the First Connecticut Infantry, to Captain in the 169th Infantry of the Connecticut National Guard in the 1920's and 1930's. His 1942 World War II draft registration card listed his residence as Cape May, NJ. He was described as 64 years old, 5'9" tall, weighing 172 lbs., with brown eyes, and gray hair. He died on March 12, 1958, and was buried in Arlington National Cemetery.
