Regiment suisse de Diesbach


1733 - 1798

Le Roi Charles Emmanuel III signa, le 14 novembre 1733, une convention avec le Colonel Albert Louis Roquin de Suerdon to raise a swiss infantry regiment called Roquin. The men are assembled from the country around the City of Berne. In 1734 the Regiment is ready in Turin with a force of two battalions.

Service during the Polish Succession War

Roquin, after garrison duties, in september 1735 is present on the west side of lake of Garda supporting the french action on the East side. At the end of the action, the 8 november, Roquin takes winter quarters in the country around Cremona and Brescia.

In 1737 the regiment changes its commander; since 17 may 1737 the new Colonel is Jean Rodolfe de Diesbach. The regiment changes its old name in Diesbach. This unit is not disbanded but the capitulation between the King and Jean Diebach is renewed for other twelve years. At the end of 1742 a 3rd battalion is raised. Each battallion has 4 companies.

Service during the Austrian Succession War

In 1742 Diesbach is campaigning in north-east Italy in the Po plains. During the spring of that year we find Diesbach in the City of Piacenza. In September the regiment is divided; the 1st and the 2nd battalions stay in garrison in Po cities, such as Modena, while the 3rd battalion marches on the Alps; from the camp of Novalesa in Susa Valley the Regiment pass the Mount Cenise gap an it takes action in Savoy during the counter-offensive against the invading Spanish army. In jenuary 1743 3rd Diesbach returns again in Piedmont. The 1st and 2nd battalions fight at Camposanto (8 february 1742). The whole regiment is reunify and marches to the west front. Behind the trenches in Varaita Valley Diesbach is waiting for the main french-spanish invasion of Piedmont. During the combats of Chateau Dauphin (8 october 1743) Diesbach is entrenched around the village of Chateau. The follow year its principal task is the control of the Alpine frontiers. The 10 april Colonel Agustine Roquin is the new commander of the regiment renamed Roquin. The Prince Conti's action reaches again the Varaita Valley. This regiment is one of the units that fight at the redoubt of Mount Cavallo during the battle of Pierre Longue (17 july 1744). During the hard combat, the 1st and 2nd battalion make a fierce defence inside the redoubt but at the end they are drived out during the last successful french attack losing 372 men. The brave Colonel Roquin, while defending with his officier's spontoon the palissade, is shot down hit at the head. Yet the 22 july the regiment has a new colonel, Charles Antoine Roy, and a new name, Roy. After the defeat the whole piedmontese army is concentrated in south west Piedmont in order to break the siege of the Place Fort of Cuneo. So the three battalions of the regiment are present at Madonna dell'Olmo (30 september 1744). Roy is situated on the right wing, first line. In 1745 the great Maillebois' offensive gives no match to the Piedmontese hope to stop it. After the battle of Bassignana (27 september 1745) Roy leaves its 3rd battalion to defend the new bult powerful Citadel of Alessandria. It helds the block of the fortess for six month (11 november 1745 &endash; 11 march 1746). The other two battalions of Roy are in the order of battle of Leutrum's army in the well planned counter offensive that clear the piedmontese landscape. Then the regiment marches in the south-west in the mediterranean theatre. But in 1747 the regiment is urgently recalled on the Alpine front. Again the 3rd battalion takes a day of glory. The battalion helds the redoubt of Gran Serin, defending it against the extremely dangerous french assault of the Marquise de Villemur's right column. The trench were defended by two battalion of Kalbermatten and the 3rd Roy against 14 enemy battalions. The defence is successful and the day is saved.

In 1751 the capitulation is extended for other twelve year. In 1760 the Regiment becomes Regiment Tscharner. In 1763 the previous capitulation is confiermed.
