When the Guglers arrived in 1375, there was a lot of destruction (symbolic image)

The Gugler invaded the Swiss Plateau 650 years ago and caused widespread destruction – but they did not achieve their goal.
In 1375, a troop of mercenaries known as the Gugler crossed into Switzerland from France. The fighters entered via the Jura and rampaged between the River Limmat and Lake Neuchâtel. Several villages disappeared from the map, although historians dispute how many were destroyed directly by the Gugler.
The mercenaries did not come by chance. The invasion occurred during the Hundred Years’ War, when frequent ceasefires left many soldiers without employment. To prevent unrest, the French crown kept them occupied. “So the king kept them busy,” explains Paul Bühler, a theologian and amateur historian from Biberist, canton Solothurn, who has studied the Gugler in detail.
At the time, the French count Ingelram de Coucy (1339–1397) commanded the mercenaries. He sought to claim an inheritance that his mother, Katharina von Habsburg, had never received. Katharina was supposed to inherit several towns – including Aarau, Lenzburg, Bremgarten (canton Aargau), Sursee and Willisau (canton Lucerne) – but she lost them in an inheritance dispute.

Fear and devastation
In December 1375, the mercenaries set out to seize what Ingelram considered his rightful due. They plundered and set fires. To deny them a stronghold, the Habsburgs themselves burned the town of Lenzburg.

The campaign lasted about a month before Swiss forces drove the Gugler back to France.
Defeat near Buttisholz
The decisive blow came at Christmas 1375, when troops from Entlebuch defeated the Gugler near Buttisholz. In the following days, they also suffered defeats at the hands of forces from Bern near Fraubrunnen and by troops from Seeland and Fribourg near Ins. A monument in Fraubrunnen still commemorates the victory.

Although the Gugler were expelled, the damage was severe. “In their search for food and warmth, the mercenaries robbed villages and set fire to farmhouses,” says Bühler.
Vanished villages
Numerous settlements disappeared during this period. In canton Solothurn, examples include the towns of Altreu and Fridau, or villages such as Waldkirch and Bienken near Oensingen, Wedelswil and Gutzwil near Solothurn, Bützingen near Lüsslingen, and Günnikofen near Lüterkofen.
This is what Altreu might have looked like around 1300. The small town with the bridge over the Aare (white) has disappeared, today Altreu is a small village.

But were the Gugler truly responsible? Bühler notes that “the plague and economic difficulties also contributed to the decline of villages”. Some may have been abandoned before the invasion.
Even today, the evidence remains uncertain. Estimates of the invading force vary widely, ranging from fewer than 20,000 to as many as 40,000 men. The cantonal archaeology department of Solothurn, for example, describes the vanished town of Altreu: “There is archaeological evidence of a fire disaster here. Whether the town fire can be blamed on the Gugler remains an open question.”
Lenzburg Castle still towers over the small town today. This is where the Habsburgs retreated to when the Gugler ravaged the Central Plateau.

Not every vanished village can therefore be attributed to the mercenaries. But 650 years ago, the Gugler certainly left a trail of destruction on the Swiss Plateau.
Theologian, pastor and amateur historian Paul Bühler has studied the Gugler in depth and is giving lectures on the 650th anniversary of the invasion.

Where does the name Gugler come from?
Gugler comes from the Middle High German word Gugel. In the 14th century, this was a type of cap, a hood, which the Gugler wore under their helmets. The word is probably also found in the famous cake, the Gugel-Hopf, as the baking tin is reminiscent of the Gugel.
