His memoirs, Reminiscences of Charles Seton Henry Hardee and Charles Seton Henry Hardee's Recollections of Old Savannah, published by his granddaughter after his death, were written when he was over the age of ninety[1] and became noted works on the history of the city's early years.

[3] After becoming widowed, Hardee's mother moved to Savannah, where her brother and two sisters, Charlotte and Fanny, had been living.

[4] The family arrived, on the sloop Virginia, at the Lower Rice Mill wharf, to the west of East Broad Street.

[6] He travelled the 250 miles along the Savannah River to Augusta, Georgia, aboard the iron steamboat Chatham.

[10] After graduating in 1848, he returned to Savannah, where he was hired by his uncle, Noble Hardee, to tutor his two oldest children.

They had ten known children: daughters Alice, Isabella, Margaret, Meta, Martha, Harriet, and Frances, and sons Charles, James, and Robert.

After a little over a year in the role, his position was filled by Lieutenant Colonel Harris, who had been relieved from active field service due to his failing health.

His role was to receive cotton arriving in Savannah from the Confederate government or by the State of Georgia and forward it through the blockade whenever the opportunity arose.

[13] He was given a position as Deputy Collector of the Port and Assistant Depositary in the Savannah Treasury Department, filling a vacancy left by the death of John Boston.

His notebook lay on his table, ready for further recollections of the development of his beloved city," wrote his granddaughter Martha Gallaudet Waring, who had his works published.
