January 1803: HMS Calcutta departed England bound for Port Phillip Bay, where a new settlement was to be established. The seven Gibraltar mutineers were aboard. Court martialled. Convicts now. Patrick McCarthy was one of them. Aged 24. Never to return to England or his Irish home.
Calcutta carried a crew of 150, 308 male convicts, civil officers, marines, and some wives and children. Sailing with her was the supply ship Ocean. They reached Rio De Janeiro on 19 July. After a short layover they sailed southward, arriving at Cape Town on 16 August. While anchored there, Calcutta received news that Britain was now at war with the Batavian Republic. The Dutch sent a representative aboard Calcutta to demand that she surrender. While the representative waited, Calcutta's Captain Woodriff spent two hours preparing her for battle. He then showed the representative Calcutta's sailors and marines at their guns, and told the Dutchman that "if he wants this ship he must come and take her if he can". The convicts were asked if any would volunteer to fight and work the ship. All volunteered (onya Patrick!). The Dutch gave Calcutta 24 hours to leave, saying that they "did not wish to capture such a large number of thieves".
