BIBLE, REV 20:7-10
After the 1,000 year period of the Millennium, Satan will be loosed and then the nations (Gog and Magog) will gather to battle against the saints.
D&C, 88:110-16
After the Millennium and the little season Satan will gather his armies and Michael will gather his armies and Michael will overcome Satan.
HC, J SMITH 5:298
The battle of Gog and Magog will be after the millennium. The remnant of all the nations that fight against Jerusalem were commanded to go up to Jerusalem to worship in the millennium.
JD, O PRATT 18:346
He [Satan] with his army will come against the Saints, and the beloved city, and encompass them round about. His army will be so great that it will be able to come upon the Saints on all sides; he is to encompass their camp. Because of the favorable position he is to hold, in that great last battle, and because of the vast number of his army, he doubtless believes that he will get the mastery and subdue the earth and possess it. I do not think he fully understands all about the designs of God: for John tells us when this great army shall be gathered in position, around the camp of the Saints, that "fire came down from God out of heaven, and devoured them." Devoured whom? Not those who are fallen angels, for they have no bodies to be devoured; but this fire from heaven will devour the wicked apostate race who will have listened to them and who will have joined Satan's army; they will be consumed, consequently the kingdom of Christ will not be overcome by Satan or taken away from the Saints.
