"I am sorry, lads," I said to them in French, "that I have been compelled to resort to subterfuge to make prisoners of you, but, you see, we are all invalids here, and not strong enough to take your ship by force; and therefore, since it is imperative that we should have her, I have been compelled to use guile.  However, I will keep my word with you in the matter of something to quench your parched throats; and if you choose to be sensible, and make no foolish attempts at escape, you shall have no reason to complain of harsh treatment."
