The red-and-white Crossland arms gained popularity in quite a different way. Probably because the yellow-and-black "Maryland colors" were popularly identified with a state which, reluctantly or not, remained in the Union, Marylanders who sympathized with the South adopted the red-and-white of the Crossland arms as their colors. Following Lincoln's election in 1861, red and white "secession colors" appeared on everything from yarn stockings and cravats to children's clothing. People displaying these red-and-white symbols of resistance to the Union and to Lincoln's policies were vigorously prosecuted by Federal authorities.
During the war, Maryland-born Confederate soldiers used both the red-and-white colors and the cross bottony design from the Crossland quadrants of the Calvert coat of arms as a unique way of identifying their place of birth. Pins in the cross bottony shape were worn on uniforms, and the headquarters flag of the Maryland-born Confederate general Bradley T. Johnson was a red cross bottony on a white field.
