The spirit of martialism in Jainism is manifest in its very own name (Jain meaning a conqueror), and the epithet accorded to the last Jain _tirthankar_ of our present yuga is Mahavir, i.e., the great hero.
In fact the first hero of Jaina lore, the greatest hero of all, and the first one to achieve moksa, according to certain Jaina traditions, is Bahubali (one with strong arms -- one of the many definitions of Bahubali).
The story of Bahubali, son of Rishabha, the first tirthankar, is told, among others, in Jinasena's _Adi-Purana_ where Jainism is described as a weapon of war (1.4), the various ascetic practices are compared to an army which conquers the enemy, karma (4.153 etc.), and the monk is instructed to abandon his body like that of an enemy on the battlefield (11.98) (see Paul Dundas, "Jain Digambar Warrior" (=DJW), in Carrithers and Humphreys, _Assembly of Listeners_ pp. 173-4).
