General Sir Aylmer Haldane, [G.C.M.G.], [K.C.B.], [D.S.O.], published an account of his escape in 1900 as How We Escaped From Pretoria. He went on to pursue a distinguished military career which culminated in his appointment as G.O.C. in Mesopotamia where he successfully suppressed the Arab Rebellion.

The debate about whether Churchill abandoned Haldane and Brockie was re-ignited with the discovery in 1997 of a letter written by Haldane in 1930, shortly after Churchill's publication of My Early Life. He wrote that 'Since the publication of his book, which maintains what I honestly think is fiction so far as his escape enters into it, I feel that I have nothing more to conceal ... The truth was that I had made all the plans with another man to escape when Churchill came into the picture. He perfectly understood that he and I were to go in company. We tried together one night, but conditions were unfavourable. The next night we tried again in company, proof that he understood we were not to go separately. [The next night] he slipped off without myself or the third man, whose abuse of Churchill I shall not forget' (The Sunday Times 24.7.1997 refers). The debate is given extensive treatment in Celia Sandys' new book and the author comes down on Churchill's side.
