Revelation 12:13; The Dragon Persecuted the Man Child

Revelation 12:13 And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child. 

Three great campaigns now take place in the earth as Satan mobilises his military might against Israel.

The battle in the land (v6, 13-15).

Revelation 12:6 And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days.

Revelation 12:13-15 And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child. And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent. And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood. 

The battle in the wilderness (v15-16).

Revelation 12:15-16 And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood. And the earth helped the woman, and the earth opened her mouth, and swallowed up the flood which the dragon cast out of his mouth. 

And the battle of the remnant (v17), Satan was thwarted.

Revelation 12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ. 

The defeat of the armies of Antichrist are not described at this point. The preparations for the battle against the remnants of Israel gathers momentum.
