The Bible did not provide a specific number. But by its description it must have been several hundred thousands. Judges 7:12 And the Midianites and the Amalekites and all the children of the east lay along in the valley like grasshoppers for multitude; and their camels were without number, as the sand by the sea side for multitude. And Gideon was able to defeat these multitude with only 300 men,
(7:16 And he divided the three hundred men into three companies, and he put a Trumpet in every man's hand, with empty pitchers, and lamps within the pitchers. ) that lapped water as a dog
(7:5 So he brought down the people unto the water: and the LORD said unto Gideon, Every one that lappeth of the water with his tongue, as a dog lappeth, him shalt thou set by himself; likewise every one that boweth down upon his knees to drink. 7:6 And the number of them that lapped, putting their hand to their mouth, were three hundred men: but all the rest of the people bowed down upon their knees to drink water. 7:7And the LORD said unto Gideon, By the three hundred men that lapped will I save you, and deliver the Midianites into thine hand: and let all the other people go every man unto his place.)
Addendum: Judges 8:10 Now Zebah and Zalmunna were in Karkor with a force of about fifteen thousand men, all that were left of the armies of the eastern peoples; a hundred and twenty thousand swordsmen had fallen.
Calculating from this passage, the armies of the eastern peoples (Midianites) began with 135,000 men. (See also John Gill Commentary - "for there fell an hundred and twenty thousand men that drew sword; besides infirm men, women, and children, which may reasonably be supposed; so that this host consisted of 135,000 fighting men").
God promised to help Gideon defeat the Midianites by giving him strength and guidance in battle.
Gideon defeated the Midianites by using a small army of only 300 men and surprising them with torches and trumpets in the middle of the night. The noise and confusion caused the Midianites to turn on each other, leading to their defeat.
defeat the Midianites;wipe them out
In the bible it clearly states that Gideon defeated the midianites.
Gideon
The Midianites
Gideon made an ephod as a way to honor and remember the victory that God had given him in battle against the Midianites.

If my interpretation of Judges chapter 7 is correct;The 300 soldiers of Gideon were armed with empty pitchers, lamps and trumphets to do battle with the " Midianites and the Amalekites and all the children of the east lay along in the valley like grasshoppers for multitude; and their camels were without number, as the sand by the sea side for multitude"
With only 300 soldiers Gideon and his men frightened the Midianite armies with trumpets and lights, the Midionites flee and are defeated by Israel. With 300 hundred trumpets blaring away as well as three hundred lights being waved about it was enough to frighten the Midianites, so much so that they were not sure who the enemy was and so fought among themselves. They were pursued by the Isaelites, their princes captured and killed and their army defeated.
The Gideon ephod was a sacred object used for seeking guidance from God in the biblical story of Gideon. It symbolized Gideon's leadership and his reliance on divine direction in battle against the Midianites. The ephod played a key role in Gideon's victory, highlighting the importance of faith and obedience in achieving success.
Gideon was the 5th Judge of Israel who was called by God - the ultimate Judge - to free the Israelites from the Midianites. The story begins in the Book of Judges chapter 6 through 8.
