[2] Lainé published an article summarizing its creed under the title Nos deux bases, Irlande et Prusse (Our two models: Ireland and Prussia), referring to the revolutionary zeal of the IRA and the authoritarian discipline of Prussian militarism.

Lainé claimed he made the first bomb in his bedroom from nitroglycerin in a condensed milk carton with a detonator supplied by a forestry worker.

Kristian Hamon claims it was not he but fellow nationalist André Geffroy who placed the bomb which blew up Jean Boucher's statue depicting the Unity of Brittany and France in Rennes.

In 1936 Lainé created the Kadervenn (Combat tool), a paramilitary unit based on the IRA model, comprising a dozen members engaged in military manoeuvres.

This organisation instructed new recruits and in 1938 participated in exercises in the Landes de Lanvaux, a belt of heath and woodland north of Vannes.

In 1941, Lainé helped to oust Olier Mordrel from the leadership of the Breton National Party when it became evident that the Germans objected to his strident anti-Vichy position.

Hunted out of Brittany after the defeat of the Nazis, the last fighters of this unit found themselves at Tübingen, from which many stayed in Germany under false identities, assisted by Leo Weisgerber.

He had become the prophet of a Celtic religion made for himself, where Nordic racism was married to the Nietzschian will to power, and not without flirting with an air of romantic druidism".
