The city of Fosses owes its origin to Saint-Feuillen or Foillan, an Irish monk who came to evangelize our country around 650 and had received a part of his estate called Bebrona (Beaver River), and later Fossa from Gertrude, the abbessa of Nivelles.
He founded a monastery of "Scots" upon these lands. The religious history teaches us that Foillan was assassinated on October 31st, 655 in the “Forêt Charbonnière”, near the Roeulx. In 656 his remains were brought back to Fosses, where Foillan became Saint Feuillen and later the patron saint of the city, with a rapidly spreading cult.
It is in his honour that processions were organized. The earliest mention in the archives is that of 1086, during the transfer of the relics to a new shrine. This religious ceremony has been organized for the past nine centuries.
The "Military March", however, only exists for certain since its inception in 1566, with a company of arquebusiers of which the statutes stipulate that they have to "find themselves in noble company, with their flags in the wind, with fifes and drums, weapons and crew, on the day they carry the glorious body of Mr. Saint Pholien".
It is therefore more to honour the relics of the patron saint than to defend them against the brigands that this military escort was provided during processions. But why is the event organized every seven years ? Because a "Vow" was made to organize processions in the early seventeenth century : the plague ravaged the region between 1634 and 1637, and it is from 1635 that this wish to hold processions every seven years was issued by the canons and the magistrates of Fosses. But it was only in 1844, that people strictly held themselves to the seven-year gap, even during the latest war in 1942.
In 1900, the procession of Saint-Feuillen already featured 25 companies and nearly 3,000 men. The crowd was estimated at more than 50,000 people and the station of Fosses, opened ten years earlier, issued 22,000 coupons!
In 1914, the preparations were interrupted by the war, but in 1918, the Dean Crépin held a moving ceremony to honour our patron saint by having his relics carried by Irish soldiers in a procession through the streets of the city centre, the day was presided over by the Abbot of Maredsous, Dom Columba Marmion, himself an Irishman.
The outings of 1921 and 1928 were more modest, and in 1935 the General Staff became a non-profit organization and really boosted the march. Despite the war, in 1942, the General Staff decided to organize the procession and obtained permission from the Kommandantur of Namur; there could be no uniforms or weapons, but companies of Fosses (without their members who were made POWs) and those of Haut-Vent, Nèvremont, and Bambois, accomplished the Tour in impeccable ranks and "armed" with... paper bags that they would blow up and pop at the officer’s command : this was of course a lot quieter than guns and blunderbusses, but the spirit was there! So this outing was called “Li Mârche ôs satchos” (the march with the bags).
For the following marches, the organizers wanted to excel by attracting more people, more guest companies and by the sumptuousness of the procession.
