What happened when Jones came to reclaim his farm?

In October, accompanied by several other farmers, Mr. Jones tries to recapture Animal Farm. Snowball has already trained the animals for war, however, and they take their defensive positions. The smaller animals attack the men and then pretend to retreat into the yard in defeat. Once the men follow, the larger animals ambush them. Mr. Jones kills one sheep and wounds Snowball several times with his gun, but the animals manage to overpower the humans. Boxer is thought to have killed a stable-lad, which upsets the stalwart horse. But it turns out that the boy is only injured, and he flees with the other men. The only animal who does not fight is Mollie, whom the animals discover cowering in her stall.

Is there a shorter way to say that?

who helped him?

From the text:

Jones and all his men, with half a dozen others from Foxwood and Pinchfield, had entered the fivebarred gate and were coming up the cart-track that led to the farm. They were all carrying sticks, except Jones, who was marching ahead with a gun in his hands.

Jones is the only man named in the attack on Animal Farm.
