He was the newspaper's special correspondent and reported on the Polish Insurrection in 1863-1864 following which he wrote a book, "Polish Experiences", published by Macmillan in 1864. His hosts, during his travels, included the Tarnowski family. Bullock described visiting the family seat at Dzików Castle where he met Count Jan Tarnowski and his two brothers, Juliusz Tarnowski and Stanisław Tarnowski. Juliusz was killed 2 weeks later fighting the Russians whilst Stanisław was condemned by the Austrians to 12-year solitary confinement in the Wawel Castle. Some months later, as Bullock returned from his wider travels back to Kraków, he sought permission to visit Stanisław in prison. Although permission was formally granted, access was denied on the morning of his visit.
