The outbreak of the Franco-Prussian War in July 1870 compelled Alma-Tadema to leave the continent and move to London. His infatuation with Laura Epps played a great part in his relocation to England and Gambart felt that the move would be advantageous to the artist's career. In stating his reasons for the move, Tadema simply said "I lost my first wife, a French lady with whom I married in 1863, in 1869. Having always had a great predilection for London, the only place where, up till then my work had met with buyers, I decided to leave the continent and go to settle in England, where I have found a true home."  With his small daughters and sister Atje, Alma-Tadema arrived in London at the beginning of September 1870. The painter wasted no time in contacting Laura, and it was arranged that he would give her painting lessons. During one of these, he proposed marriage. As he was then thirty-four and Laura was now only eighteen, her father was initially opposed to the idea. Dr Epps finally agreed on the condition that they should wait until they knew each other better. They married in July 1871. Laura, under her married name, also won a high reputation as an artist, and appears in numerous of Alma-Tadema's canvases after their marriage (The Women of Amphissa (1887) being a notable example). This second marriage was enduring and happy, though childless, and Laura became stepmother to Anna and Laurence. Anna became a painter and Laurence became a novelist.  He would initially adopt the name Laurence Alma Tadema instead of Lourens Alma Tadema and later adopt the more English Lawrence for his forename, and incorporate Alma into his surname so that he appeared at the beginning of exhibition catalogues, under "A" rather than under "T". He did not actually hyphenate his last name, but it was done by others and this has since become the convention.

Answer this question "What did he do when he arrived there?" by extracting the answer from the text above.
