The Second Fleet is the name of the second group of ships sent with settlers, convicts and supplies to colony at Sydney Cove in Port Jackson, Australia. There were six ships in the fleet: one Royal Navy Escort, four convict ships, and a supply ship.
The ships were meant to sail to Australia together, and get to Sydney Cove in 1789. However the escort ship was wrecked on the way and did not arrive, and one convict ship was delayed and arrived two months after the other ships.
Unlike the First Fleet, where great efforts were taken to keep the convicts healthy, the Second Fleet was run by private businesses who kept the convicts in horrific conditions. When they got to Sydney, the sick convicts were a drain on the already struggling colony.
