Task: Question Understanding
Input (English): Passage: Moving back west, by 13 June 1497 the Cornish army arrived at Guildford. Although shocked by the scale of the revolt and the speed of its approach, Henry VII had not been idle. The army of 8,000 men assembled for Scotland under the command of Giles, Lord Daubeny, Henry's chief general and Lord Chamberlain, was recalled. Then the Earl of Surrey was sent north to conduct a defensive, holding operation against the Scots until such time as the King had quelled his domestic difficulties. The Royal family  moved to the Tower of London for safety whilst in the rest of the City there was panic among the common citizens. It is said there was a general cry of 'Every man to harness! To harness!' and a rush of armed citizenry to the walls and gates. Then, the same day that the Cornish arrived at Guildford, Daubeney and his men took up position upon Hounslow Heath and were cheered by the arrival of food and wine dispatched by the Lord Mayor of London. The Crown decided to take the offensive and test the strength and resolve of the Cornish forces. Lord Daubeney sent out a force of 500 mounted spearmen and they clashed with the Cornish at 'Gill Down' outside Guildford on Wednesday 14 June 1497. The Cornish army left Guildford and moved via Banstead and Chussex Plain to Blackheath where they pitched their final camp, looking down from the hill onto the Thames and City of London. Despite unrest among the Cornish forces, An Gof held his army together, but faced with overwhelming odds, some Cornish deserted and by morning there remained only some 9-10,000 Cornish stalwarts left in arms.
Question: When did Daubeney and his men take up position upon Hounslow Heath?
