On 18 August, five cannon brought down from Edinburgh Castle to the Netherbow Port at St Mary's Wynd for the invasion set off towards England dragged by borrowed oxen.
On 19 August two 'gross culverins', four 'culverins pickmoyance' and six (mid-sized) 'culverins moyane' followed with the gunner Robert Borthwick and master carpenter John Drummond.
The King himself set off that night with two hastily prepared standards of St Margaret and St Andrew.

Catherine of Aragon was Regent in England.
On 27 August, she issued warrants for the property of all Scotsmen in England to be seized.
On hearing of the invasion on 3 September, she ordered Thomas Lovell to raise an army in the Midland counties.

In keeping with his understanding of the medieval code of chivalry, King James sent notice to the English, one month in advance, of his intent to invade.
This gave the English time to gather an army and to retrieve the banner of Saint Cuthbert from Durham Cathedral, a banner which had been carried by the English in victories against the Scots in 1138 and 1346.
After a muster on the Burgh Muir of Edinburgh, the Scottish host moved to Ellemford, to the north of Duns, Scottish Borders, and camped to wait for Angus and Home.
The Scottish army then crossed the River Tweed near Coldstream.
On 24 August, James IV held a council or parliament at Twiselhaugh and made a proclamation for the benefit of the heirs of anyone killed during this invasion.
By 29 August Norham Castle was taken and partly demolished.
The Scots moved south, capturing the castles of Etal and Ford.

A later Scottish chronicle writer, Robert Lindsay of Pitscottie, tells the story that James wasted valuable time at Ford enjoying the company of Elizabeth, Lady Heron and her daughter.
Edward Hall says that Lady Heron was a prisoner (in Scotland), and negotiated with James IV and the Earl of Surrey her own release and that Ford Castle would not be demolished for an exchange of prisoners.
The English herald, Rouge Croix, came to Ford to appoint a place for battle on 4 September, with extra instructions that any Scottish heralds who were sent to Surrey were to be met where they could not view the English forces.
Raphael Holinshed's story is that a part of the Scottish army returned to Scotland, and the rest stayed at Ford waiting for Norham to surrender and debating their next move.
James IV wanted to fight and considered moving to assault Berwick-upon-Tweed, but the Earl of Angus spoke against this and said that Scotland had done enough for France.
James sent Angus home, and according to Holinshed, the Earl burst into tears and left, leaving his two sons, the Master of Angus and Glenbervie, with most of the Douglas kindred to fight.
