Revelation 19:16-21
"And he hath on his vesture and on his thigh a name written, King Of Kings, And Lord Of Lords. And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God; That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great. And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army. And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone. And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh."
This was the literal physical battle of Armageddon. Chapter 16 was the 3 spirits calling them to this physical battle. 17 and 18 was the symbolic application of the state of affairs the whole world was in at the end of those 42 months.
You cannot ignore the actual physical battle. You cannot separate the FP, the beast, and Satan from this physical event. The FP and the beast were tossed into the lake of fire. Satan was bound in the pit. This was the end of those 42 months to the hour.
The last hour was when the 10 kingdoms show up and join with Satan, the FP, and the beast. The battle was only an hour, because that was the only hour God allowed, the battle itself. Did the actual battle last for an hour? Hard to say. There was either time allowed for any to change their minds, or Jesus literally took an hour to kill every last one of them, instead of doing it instantly.
Well I don’t see revelation 19 as a literal battle but that’s a different debate but let’s see the differences in revs 16 and revs 19 battles
Rev 16:16-21
16 Then they gathered the kings together to the place that in Hebrew is called Armageddon.
17 The seventh angel poured out his bowl into the air, and out of the temple came a loud voice from the throne, saying, “It is done!” 18 Then there came flashes of lightning, rumblings, peals of thunder and a severe earthquake. No earthquake like it has ever occurred since mankind has been on earth, so tremendous was the quake. 19 The great city split into three parts, and the cities of the nations collapsed. God remembered Babylon the Great and gave her the cup filled with the wine of the fury of his wrath. 20 Every island fled away and the mountains could not be found. 21 From the sky huge hailstones, each weighing about a hundred pounds, fell on people. And they cursed God on account of the plague of hail, because the plague was so terrible.
See above above that Babylon the great is judged we also see all through chapter 18 and who destroys Babylon the great?
Rev 17:16-17
16 The beast and the ten horns you saw will hate the prostitute. They will bring her to ruin and leave her naked;they will eat her flesh and burn her with fire. 17 For God has put it into their hearts to accomplish his purpose by agreeing to hand over to the beast their royal authority, until God’s words are fulfilled
Yes the beast and the 10 horns. We also see earlier in chapter 16 that the beast is in the battle of rev 16.
Now in the verses of rev 19 which you provided there is no mention of the term Armageddon or Babylon the great but we do see that it’s actually the destruction of the beast and the false prophet
