Plato, Laws 944c

δικαίως, ἀποβολεὺς δὲ ὅπλων. οὐχ ὁμοίως γὰρ ὅ τε ἀφαιρεθεὶς μετʼ εἰκυίας βίας γίγνοιτʼ ἂν ῥίψασπις ὅ τε ἀφεὶς ἑκών, διαφέρει δὲ ὅλον που καὶ τὸ πᾶν. ὧδʼ οὖν δὴ λεγέσθω νόμῳ· ἐὰν καταλαμβανόμενός τις ὑπὸ πολεμίων καὶ ἔχων ὅπλα μὴ ἀναστρέφῃ καὶ ἀμύνηται, ἀφῇ δὲ ἑκὼν ἢ ῥίψῃ, ζωὴν αἰσχρὰν ἀρνύμενος μετὰ κάκης μᾶλλον ἢ μετʼ ἀνδρείας καλὸν καὶ εὐδαίμονα θάνατον, τοιαύτης μὲν ὅπλων ἀποβολῆς

For the man who by a fair amount of violence is stripped of his arms will not be as much of a shield-flinger as the man who has voluntarily thrown them away—rather there is a vast difference between the two cases. So let the pronouncement of the law be this:—If a man is overtaken by his enemies and, having arms, instead of turning and defending himself, voluntarily drops his arms or flings them away, thereby gaining for himself a life that is shameful by speed of foot, rather than by bravery a noble and blessed death,—concerning the arms flung away in a loss of this sort a trial shall be held, but the judge shall pass over in his enquiry a case of the kind previously described.
