The Dear Admiral
According to William Groom (1899-1900, cited by Bosman, 1980 on p. 203), a play called either The Dear Admiral or simply Dear Admiral was done in the Harrington Street Theatre, Cape Town, by the LeRoy-Duret Company during their first season, being played on 20 and 26 April, 1866. No author is mentioned.
No reference to a play by this name can be found, though there is a reference by Bogar (20**) to an anonymous play called The Rear Admiral (also by an anonymous author), performed in Baltimore in 1845 by the comedian John E. Owens (1823-1886)[1]
