The wedding between Langtry and de Bathe took place in St Saviour's Church, Jersey, on 27 July 1899, with Jeanne Marie Langtry being the only other person present, apart from the officials. This was the same day that Langtry's horse Merman won the Goodwood Cup. In December 1899, de Bathe volunteered to join the British forces in the Boer War. He was assigned to the Robert's Horse Mounted brigade as a lieutenant. In 1907, Hugo's father died; he became the 5th Baronet, and Langtry became Lady de Bathe.
