The Battle of Deptford Bridge (also known as Battle of Blackheath) took place on 17 June 1497 on a site in present-day Deptford south-east London, near the River Ravensbourne and was the climax of the Cornish Rebellion. Henry VII had an army of some 25,000 men and the Cornish lacked the supporting cavalry and artillery arms essential to the professional forces of the time. After carefully spreading rumours that he would attack on the following Monday, Henry moved against the Cornish at dawn on Saturday (17 June 1497). The Royal forces were divided into three 'battles', two under Lords Oxford, Essex and Suffolk, to wheel round the right flank and rear of enemy whilst the third waited in reserve. When the Cornish were duly surrounded, Lord Daubeney and the third 'battle' were ordered into frontal attack.
