on 13 May 1787; provided an escort out of British waters. On 3 June 1787, the fleet anchored at Santa Cruz, Tenerife. On 10 June they set sail to cross the Atlantic to Rio de Janeiro, taking advantage of favourable trade winds and ocean currents. The Fleet reached Rio de Janeiro on 5 August and stayed for a month to resupply. The Fleet left Rio de Janeiro on 4 September to run before the westerlies to Table Bay in Southern Africa, which it reached on 13 October; this was the last port of call before Botany Bay. On 25 November, Phillip transferred from the Sirius to the faster Supply, and with the faster ships of the fleet hastened ahead to prepare for the arrival of the rest of the fleet. However, this "flying squadron", as Frost called it, reached Botany Bay only hours before the rest of the Fleet, so no preparatory work was possible. Supply reached Botany Bay on 18 January 1788; the three fastest transports in the advance group arrived on 19 January; slower ships, including Sirius, arrived on 20 January. Phillip soon decided that the site, chosen on the recommendation of Sir Joseph Banks, who had accompanied James Cook in 1770, was not suitable, since it had poor soil, no secure anchorage, and no reliable water source. Cook was an explorer and Banks had a scientific interest, whereas Phillip's differing assessment of the site came from his perspective as, quoted by Tyrrell, "custodian of over a thousand convicts" for whom he was responsible. After some exploration, Phillip decided to go on to Port Jackson, and on 26 January, the marines and the convicts landed at a cove, which Phillip named for Lord Sydney. This date later became Australia's national day, Australia Day. Governor Phillip formally proclaimed the colony on 7 February 1788 in Sydney. Sydney Cove offered a fresh water supply and a safe harbour, which Phillip famously described as: "being with out exception the finest Harbour in the World [...] Here a Thousand Sail of the Line may ride in the most perfect Security." Establishing a settlement On 26 January, the Union Jack was raised, and possession of the land was taken formally in the name of King George III. The next day, sailors from Sirius, a party of marines, and a number of male convicts were disembarked to fell timber and clear the ground for
