On the 21st there was a ball with over 500 guests in St. George's Hall. "Djambi" next continued to Sydney, where the officers dined on 30 May. On 6 June the governor and other dignitaries visited "Djambi". On 8 June there was a ball. On 20 June the Djambi left Sidney for Batavia. On 23 July 1863 "Djambi" arrived in Batavia. On 12 August she left Batavia, obviously to go to Surabaya where she was being repaired in late August. On 13 September the Djambi left Surabaya, and she arrived back in Batavia on 17 September. In 1863 there was a lot of tension between Japan and western powers about opening the country to foreign trade. After some rumors had circulated, "Djambi" left Batavia for Japan on 26 September 1863. The commander would try to sail most of the way from Batavia to Nagasaki, but would be forced to use the engines due to many head winds. On 7 October "Djambi" arrived in Hong Kong to bunker. She left for Nagasaki on 14 October, arriving there on the 26th. The first action for Van Rees would be to contact the Medusa, and to take command of all the Dutch ships in Japan, meaning the "Medusa", which was in Yokohama. On 11 November the "Medusa" arrived in Nagasaki, and after Van Rees took overall command of the ships, "Djambi" continued to Yokohama. Both ships were primarily meant to protect trade interests and Dutch citizens. On 25 February 1864, Rutherford Alcock the British minister to Japan, arrived in Nagasaki on the warship "Argus". He had orders to open the Straits of Shimonoseki, which had been kept closed to foreign shipping by the Chōshū clan. On 15 May both the "Medusa" and "Djambi" were in Yokohama, waiting for the "Metalen Kruis" (which would arrive 28 June) and the steam paddle ship "Amsterdam" (which would arrive 4 July). On 20 May the British first rate ship of the line "Conqueror" arrived with 588 marines. After this fleet had been assembled the forces of the United Kingdom, the Netherlands, France and the United States were brought under the command of English Vice-Admiral Kuper. In mid-July the English warships "Barossa" and "Cormorant" were sent to hand the Chōshū clan an ultimatum.
