what is the watchword?how does boxer react?

Squealer tells the animals, “Discipline, comrades, iron discipline! That is the watchword for today.” Again as in the case of the milk and apples, Squealer ensures the animals’ compliance by threatening Mr. Jones’s return. Of all the animals, Boxer takes obedience to the pigs to heart most. He now has two personal maxims: “Napoleon is always right” and “I will work harder” (70).
