"To Lucasta, Going to the Wars" is all about sacrifice. After all, the speaker leaves behind the woman he loves in order to go to war and be honorable. He makes a point of describing the extent of his sacrifice: the woman he is leaving behind is nothing short of awesome. We mean, her name is Lucasta, which means "chaste light." But no matter how good she may be, the speaker suggests, going to war is even more important.
Sacrificing love for honor is better than the alternative.
No way. Any person worth his salt would sacrifice honor for love, any day.
