I have seen the term "French pockets" used for dog ear and mule ear pockets. Does anyone know if the terms "mule ear pockets" and "dog ear pockets" were used during the Civil War? Was "French pockets" a Civil War period term?
"The uniform trowsers for both officers, and enlisted men, shall, in cold weather, be of cloth, with French pockets, made loose, and to spread will over the boot, of white and light blue mixed, commonly called sky blue mix."
Note the regulations use the term "French pockets".
