Interesting Random Facts--The Grand Old Duke of York

Via Wikipedia
Like most Nursery Rhymes, the historical origins of The Grand Old Duke of York are unclear.  But the top historical candidates are:

• Richard, Duke of York (1411–1460), who was defeated at the Battle of Wakefield on 30 December 1460. Richard's army, some 8,000 strong, was awaiting reinforcements at Sandal Castle in Wakefield (the castle was built on top of a Normanmotte). He was surrounded by Lancastrian forces some three times that number, but chose to sally forth to fight. Richard died in a pitched battle at Wakefield Green, together with between one third and one half of his army.^[4]
• James II (1633–1701), formerly Duke of York, who in 1688 marched his troops to Salisbury Plain to resist the invasion from his son-in-law William of Orange, only to retreat and disperse them as his support began to evaporate.^[5]
• The most common attribution is to Prince Frederick, Duke of York and Albany (1763–1827), the second son of King George III and Commander-in-Chief of the British Army during the French Revolutionary Wars and the Napoleonic Wars.^[1] His one field command of significance was the Flanders Campaign of 1793–4, which resulted in the heavy defeat at the Battle of Tourcoing (1794), followed by his recall to England.^[6] Flanders having something of a reputation for being flat, the specific location of the "hill" in the nursery rhyme has been hypothesized to be the town of Cassel which is built on a hill which rises 176 metres (about 570 feet) above the otherwise flat lands of Flanders in northern France.^[1]
