Reported totals vary between secondary sources (one gives roughly 8,000, including around 4,500 Irish troops and German mercenaries under Martin Schwartz, plus English recruits gained along the march), but exact numbers for this leg of the campaign are not confirmed by primary sources.
Simnel March into Yorkshire 1487 was a Tudor march, fought in the area of Yorkshire, England in 1487. The city of York refused Simnel's Yorkist force entry; a related diversionary raid by Lord Scrope on York's Bootham Bar (12 June) and a royal detachment under Henry Clifford sent from York towards Tadcaster were both repelled by the rebels, but the main army failed to gain York or significant further recruitment and continued its march south towards Stoke Field, where it was defeated on 16 June 1487.
The site of Simnel March into Yorkshire 1487 lies on Triassic Rocks (Undifferentiated), bedrock that formed in the Triassic. The rock here is sandstone and conglomerate, interbedded.
