7th Va. Cav. - 1 killed 3 wounded 1 captured = 5(Armstrong, 7th Va. Cav. p. 59)
11th Va. Cav. - 5 killed 6 wounded 2 captured = 13 (Armstrong 11th Va. Cav. p. 54)
12th Va. Cav. - 1 killed 6 wounded 1 captured = 8 (Fryle 12th Va. Cav. p. 48)
Total: 7 killed 15 wounded 4 captured = 26
These figures are based on the compiled service records of the regiments. Since CSRs never include all the casualties, these figures are certainly too low.
