Johnston, like Lee, never forgot the magnanimity of the man to whom he surrendered. He would not allow criticism of Sherman in his presence. Sherman and Johnston corresponded frequently, and they met for friendly dinners in Washington whenever Johnston traveled there. When Sherman died, Johnston served as an honorary pallbearer at his funeral. During the procession in New York City on February 19, 1891, he kept his hat off as a sign of respect, although the weather was cold and rainy. Someone concerned for his health asked him to put on his hat, to which Johnston replied, "If I were in his place, and he were standing here in mine, he would not put on his hat." He did catch a cold that day, which developed into pneumonia and Johnston died 10 days later in Washington, D.C. He was buried next to his wife in Green Mount Cemetery, Baltimore, Maryland.
