Whether fortitude is properly about dangers of death in battle?

Objections

Objection 1 : It seems that fortitude is not properly about dangers of death in battle. For martyrs above all are commended for their fortitude. But martyrs are not commended in connection with battle. Therefore fortitude is not properly about dangers of death in battle.
Objection 2 : Further, Ambrose says (De Offic. i) that "fortitude is applicable both to warlike and to civil matters": and Tully (De Offic. i), under the heading, "That it pertains to fortitude to excel in battle rather than in civil life," says: "Although not a few think that the business of war is of greater importance than the affairs of civil life, this opinion must be qualified: and if we wish to judge the matter truly, there are many things in civil life that are more important and more glorious than those connected with war." Now greater fortitude is about greater things. Therefore fortitude is not properly concerned with death in battle.
Objection 3 : Further, war is directed to the preservation of a country's temporal peace: for Augustine says (De Civ. Dei xix) that "wars are waged in order to insure peace." Now it does not seem that one ought to expose oneself to the danger of death for the temporal peace of one's country, since this same peace is the occasion of much license in morals. Therefore it seems that the virtue of fortitude is not about the danger of death in battle.
