[1] Sackville was first recorded as a cricketer in 1734 when he and his brother, Lord Middlesex, played for a Kent side against one from Sussex at Sevenoaks Vine.
[2][3] In August 1735, Sackville captained Kent to victory against Sir William Gage's Sussex side on the same ground.
[7] The couple's parents were furious, and the Prince of Wales compensated Sackville for any loss of income, making him a lord of his bedchamber in 1745, and thus securing him as a recruit to his party.
[11][8] Finally, he was committed to a private lunatic asylum circa 1746, then sent abroad to exile on a very small allowance in Lausanne where Lord Shelburne met him in 1760, and commented on his dirty condition but lucid conversation.
[8] According to his descendant Robert Sackville-West, 7th Baron Sackville in his book Inheritance he became insane later in life, dying in Geneva, Switzerland, aged 52.
