On 4th March 1520, Lionel II and Ferdinand, Duke of Calabria were preparing to set sail from Nice to Palermo. Lionel had pulled together another 38,000 soldiers from the Burgundian royal army, joined by 8,000 men led by Charles III, Duke of Savoy, who was feudally bound to support Lionel’s invasion. Just over a month into King Edmund II’s rule over the nominal kingdom of Britannia, Lionel soon pursued a renewal of strong relations between Burgundy and the united British Isles by offering his son and heir Alexander to Edmund II’s two-year-old daughter Margaret, Princess of England. Edmund II didn’t instantly accept the proposal, as he was already fielding a slew of offers of marriage, including an offer made on behalf of the six-year-old grandson of Emperor Maximilian named Francis, after his maternal grandfather King Francis I of Brittany, and from the fifteen-year-old King Edward I of Brittany. Edmund, preferring to focus on the internal issues he faced, chose to leave the marriage of his daughter alone for now, and pointedly refused to take a side in the coming Austro-Burgundian War. This way, Edmund could see who won in the coming war, and accept the corresponding marriage offer while he worked on being recognised as the King of Britannia.
By 7th March 1520, no more preparations could possibly be made for the invasion of Sicily, and the Burgundian fleet set sail in the early hours of the morning, when the sun was still rising over the east. By early on the 8th, the fleet arrived at Palermo, and Ferdinand of Calabria disembarked his ship on a rowing boat to make an emotional appeal to the people of Sicily to support him, but this initial plan failed. The people of Palermo had done well out of the Habsburg trade, benefitting from the increase in trade between Sicily and the rest of the Habsburg lands. After realising this was the case, Ferdinand told the people that if they supported his bid for the throne, Sicily and Naples would have full access to trade with Burgundy, including its possessions in Egypt and the Middle East. This offer was enough to secure at the very least the co-operation of Palermo, who overpowered the imperial garrison in the town and opened the harbour for the Burgundian fleet to dock and disembark. However, even though the people of Palermo had of course heard of Lionel II’s military might, they weren’t willing to throw any more support behind Calabria, and he had to be content with just having the port functional. Lionel then sent out assault parties from his base in Palermo to capture the surrounding towns and villages, at each one spreading the news of Calabria’s return to Sicily and his alliance with Burgundy. However, initial progress was slow. Maximilian had anticipated an invasion of Sicily and had reinforced several key towns across the island. This war was to see two of Europe’s most powerful armies doing battle with each other. At first, the Burgundian front was stuck around Palermo, but then came shocking news from the heart of the Holy Roman Empire – on 26th March 1520, Emperor Maximilian died.
The death of Maximilian Habsburg left the imperial throne in the hands of his oldest son Friedrich Habsburg. Due to the Pope’s support of the Burgundian invasion of Sicily and Naples, Friedrich was not to be crowned as Emperor in Rome, but Maximilian himself had broken the tradition of the emperor requiring coronation by the Pope in 1508 when he declared himself emperor in Trent. Therefore, Friedrich travelled down to Trent, where he organised for himself a ‘triple coronation’ – in one day, he was crowned Emperor Friedrich IV, King Friedrich I of France, and (in a move that made it abundantly clear that he intended to fight Lionel and Calabria) King Friedrich II of Naples. Friedrich was married to Anne of Brittany, the daughter of King Francis I of Brittany and Elizabeth of York [1], and thus this marked the beginning of a crack between the nations of Burgundy and Brittany, who had until now been allies. Anne convinced King Edward I of Brittany to support her husband, and for a few years, he agreed to do so. Eventually, though, the Breton role in the Austro-Burgundian War would lead to the Breton Civil War [2]. Edward I was present at Friedrich’s triple coronation at Trent on 5th May 1520, thus making clear the alliance between the Empire and Brittany. Shortly after Friedrich’s coronation, the emperor – who was the same age as Lionel II, both of them having been born in 1483 – travelled south to Naples and over to Sicily, where he intended to repel the Burgundian invasion and kill Calabria.
Once Friedrich was back in Naples, he had an army of 40,000 with him. Well aware that he might have to contend with the papal armies if Pope Leo X decided to involve himself more heavily with the campaign, Friedrich also hired a contingent of Swiss mercenaries to patrol the border between Naples and the papal states. Meanwhile, his army moved further south through Naples, and he arrived on the island of Sicily on 29th May. By now, the Burgundian army had secured most of western Sicily, roughly forming a line between Termini Imerese on the northern coast and Licata on the southern coast. Lionel and Friedrich had their first battle on 4th June at the Battle of Caltanissetta, in central Sicily. This battle was one of Friedrich’s few tactical blunders – he underestimated the amount of men marching on Caltanissetta and thus went with far too few men to successfully defeat Lionel. It was an important lesson to the Emperor – never underestimate the enemy. Suffering heavy losses, Friedrich was forced to retreat from Caltanissetta, but not before ordering an artillery bombardment against the Burgundians. Lionel was wounded in the bombardment, but he managed to survive, although this couldn’t be said for many of his men. This taught Lionel an equally valuable enemy – his previous victories had been against an army with very little in the way of artillery or modern weaponry, as the Mamluks had been using outdated tactics against the Burgundians. The Habsburg army had no such disadvantage, and this war would be a far more equal war than the Burgundian Crusade had been.
