The witches (or rather their spirits, not the witches themselves) said that Macbeth never would vanquished be until Birnam Wood came to high Dunsinane Hill. Normally, you wouldn't imagine that a forest could uproot itself and move, but Malcolm's army cut down parts of the trees to use as camouflage, which they carried to Dunsinane. So in a sense the forest did move, in a kind of legal loophole way.
Malcolm's army fulfills the witches' prophecy by advancing on Macbeth's castle while carrying branches from Birnam Wood, which aligns with the prophecy that Macbeth will fall when Birnam Wood comes to Dunsinane. This clever tactic disguises their true numbers and creates the illusion that the forest is moving. Additionally, Malcolm's ascent to the throne after Macbeth's defeat reflects the prophecy's foretold end of Macbeth's reign, restoring order to Scotland. Thus, the witches' predictions come to fruition through Malcolm's strategic actions and the eventual downfall of Macbeth.

Malcolm orders the English army to cut down branches from Birnam Wood and use them to disguise their numbers as they approach Macbeth's castle at Dunsinane. This fulfills the witches' prophecy to Macbeth that he would not be defeated until Birnam Wood comes to Dunsinane.
Malcolm MacLeod - British Army officer - was born in 1882.
Malcolm MacLeod - British Army officer - died in 1969.
Macbeth is upset when he sees Malcolm's army carrying branches from Birnam Wood because it fulfills the witches' prophecy that he would not be defeated until Birnam Wood moved to Dunsinane. This sight signals to Macbeth that his downfall is imminent, as the prophecy is seemingly coming true.
Banquo and Macbeth. Not Malcolm, that's for sure, who has to be rescued from the battle by the bloody sergeant.
The witches predict that Macbeth should be wary of Macduff, as he is a potential threat. This comes true when Macduff leads an army to overthrow Macbeth. They also predict that Macbeth will not be defeated until Birnam Wood comes to Dunsinane. This comes true when Malcolm's army uses tree branches from Birnam Wood as camouflage to approach Macbeth's castle.
Macbeth's army is loyal to him out of fear and intimidation, while Malcolm's army is loyal to him out of respect and loyalty to his rightful claim to the throne. Additionally, Macbeth's army is fueled by ambition and desire for power, whereas Malcolm's army fights for justice and to restore order in the kingdom.

The Thanes (I assume that is what you meant) did not raise the army themselves, but joined an English army raised by Malcolm and his English buddies. But Macbeth didn't care because he figured he was safe because of the witches' prophecies. When those prophecies start coming true he starts to worry.
