A chaplain is the minister of the Prince of Peace serving the host of the God of War--Mars. As such, he is as incongruous as a musket would be on the altar at Christmas. Why, then, is he there? Because he indirectly subserves the purpose attested by the cannon; because too he lends the sanction of the religion of the meek to that which practically is the abrogation of everything but brute Force.
