Placed on an elevated position like the strategic hatchet-polishers, these men separate old ropes into loose strands (oakum). They play a secret policing role, keeping an attentive eye on everything that happens on the San Dominick to make sure that relative order is maintained, so as not to alarm Captain Delano. However, despite their role as sentinels, they attract Delano’s attention when they hit a sailor with a knife after the man expresses hope that Delano might free the Spaniards. Through this violent deed, they provide a first clue that the black slaves, not the Spanish sailors, might actually be in charge.
