At the time of the rebellion, there is little exact detail as to where Jones and his people are going. We are given the fact that they ran off from the farm, but little exact location is given. This might contribute to how overwhelmed they were with the animals' revolt. Exact escape plans could not be constructed in the intensity of the moment:
The situation was quite out of their control. They had never seen animals behave like this before, and this sudden uprising of creatures whom they were used to thrashing and maltreating just as they chose, frightened them almost out of their wits. After only a moment or two they gave up trying to defend themselves and took to their heels. A minute later all five of them were in full flight down the cart-track that led to the main road,
with the animals pursuing them in triumph.
Orwell indicates that Mrs. Jones left the farm "another way." In the end, all of the humans left the farm, being "chased" by the animals to the main road. The presumption that could be made is that Jones made his way to Willingdon. In Chapter 4, this is where he is found, trying to enlist the help of any human who would listen to him and his tale of woe:
Most of this time Mr. Jones had spent sitting in the taproom of the Red Lion at Willingdon, complaining to anyone who would listen of the monstrous injustice he had suffered in being turned out of his property by a pack of good-for-nothing animals.
Given Jones' penchant for drink and the fact that the Red Lion was a location he frequented even before the animals threw him out, it might make sense that this is where he wound up when he was overrun from the farm.
