The ten or more dangerous parties singled out for prosecution were still at large, and Pels realized that if these men entrenched themselves in their adobe houses, defending themselves through loopholes, it would be most difficult to capture them. Thus he wired J. P. Lower and Sons of Denver: ``Have you any percussion hand grenades for throwing in a house or across a well loaded with balls or shrapnel shot?

His problem then became one of restraining the American fighters who wanted to clean out the Vermejo by force immediately.
