Well, not a “Confederate General’s” hat. Just looks like a slouch hat with cavalry insignia (crossed sabres) and a Lt Colonel’s rank insignia (silver leaf). The CSA didn’t use that since they did officer’s rank via the collar markings* and the Union at that time I think indicated rank via the shoulder strap markings.

* - And even then they didn’t use the golf leaf/silver leaf markings for major and Lt Col. One star (large) was major; two stars was Lt Col, three stars was a Colonel. Three stars in a wreath was the collar marking for all four ranks of general.
