What was the outcome of Don Quixote's meeting with the prisoners?

As we might expect, the outcome of this encounter is not one that Don Quixote had bargained for. When the Don sees some prisoners in chains on their way to the ships to be used as galley-slaves, his curiosity is piqued. The ever-cautious, ever-sensible Sancho Panza wisely advises his master not to interfere with the chain gang, but the Don wants to know why these men are being held against their will.
So he proceeds to ask each man to tell his story. Although the prisoners embroider their stories to make it seem that the authorities are justified in punishing them, the Don is more concerned by the fact that the men are in chains. For him, this is intolerable, and Don Quixote, being Don Quixote, performs what he thinks is another noble deed by charging at the soldiers guarding the prisoners.
In the ensuing struggle, the prisoners manage to escape. Having helped free the men, Don Quixote insists that they present themselves to his beloved Dulcinea, which, understandably, they refuse to do. Not surprisingly, they just want to make themselves scarce before the authorities catch up with them—but not before they've attacked the Don and made off with his and Sancho's possessions. As always, Sancho was right, and now he's terrified that the Holy Brotherhood, the nearest thing to a police force in this neck of the woods, will come after him and the Don for helping free the prisoners.
