The Romance of Golden Star by George Griffith

Although Hartness was a much taller and broader man than the Spaniard, his long, loose overcoat fitted him well enough for the occasion, and when he had put on his shako, and wrapped his scarf about his neck so as to hide his fair beard, he was disguised enough to pass in the darkness for one of the enemy. We now took the two soldiers who had been with the officer and visited all the posts. We found four of the sentries who could not return the password and were therefore enemies. These we disarmed and bound instead of killing them, for I could see that what I had done had pleased my friend but little, though he saw that in such a desperate venture as ours it was necessary to use desperate measures.

When we had gone the rounds and made sure of all, we buried the two dead men, and took our prisoners into one of the caves under the carved stones. Then I posted my men so as to guard all the approaches from the city to the Rodadero, and after that I went with Hartness to the hidden hole by the Sayacusca, and showed him how the way to the Hall of Gold was opened. I did this so that the secret might be in good and safe hands if I should fall in battle, and so that he should be able to properly protect the welfare of Ruth and Golden Star, and fulfil my promises to himself and the professor.
