Perhaps the greatest tribute to William T. Sherman was paid by his old Civil War opponent Joe Johnston, who had fought him in Georgia and had signed with him an armistice after the Battle of Bentonville in April 1865. The two became friends. General Johnston attended Sherman's funeral in New York in 1891, stood in the rain to watch the cortege pass, and caught a cold. It caused Johnston's death two weeks later.
Rain has been a long time literary symbol or forshadowing of death. Sometimes life imitates art.
