Wales by the time she reached Tenerife, the least for any First Fleet transport. Indeed, Phillip wrote to Admiralty advising that "the convicts are not so sickly as when we sailed," though the women aboard Prince of Wales had no new clothing and were still in the ragged apparel they had worn in prison. There was no ship's surgeon aboard but Chief Surgeon John White, periodically came on board from Sirius when weather and sailing conditions permitted. As the Fleet headed toward Rio in July, humid conditions and heavy rains generated a "plague of bugs" below decks with more than a hundred insects found in one small sleeping area alone. There were also reports of rats, fleas and lice, and an outbreak of scurvy in late December. Despite this, serious illness remained rare and the first convict death was from accidental causes rather than disease. On 24 July the ship's longboat fell from a boom and struck 22-year-old Jane Bonner in the head; she died from her injuries six days later. A second convict, John Hartley, died of unknown causes on 5 August. The fact that Hartley was flogged, as punishment for the alleged planned mutiny, may have contributed to his poor health and subsequent death. These two deaths compared favourably with those on other transports, particularly Alexander; Alexander recorded 30 deaths, a consequence of overcrowding and an overflowing bilge. Convict discipline was also well maintained, except for prostitution between the female convicts and the crew, which was rampant on Prince of Wales, Friendship and Lady Penrhyn. The first recorded punishment of a convict aboard Prince of Wales was in October 1787, nearly nine months after she had sailed; six lashes for a woman caught stealing from her fellows while they were "at prayer." Marines The ship also carried a contingent of 31 marines of the New South Wales Marine Corps, comprising lieutenants Thomas Davey and Thomas Timins, five non-commissioned officers, and 24 privates. Sixteen of the marines embarked with their wives, and there were six children. Discipline was poor. In June 1787 two marines were court-martialed for disobeying orders; one received 300 lashes. Later in the voyage, two sergeants refused to share a mess after one insulted the other's wife. Drunkenness was also common. In June one drunken marine sergeant fell through an open hatchway and injured the pregnant wife of another marine, for which offence he was placed
