This is a very interesting angle. If we apply the strict definition of “no casualties at all,” there is no recorded war in the Bible with zero deaths, because warfare in the biblical narrative typically involves killing, judgment, or deliverance.
However, if we interpret “no deaths” as **“the Israelites did not use weapons, or the enemy was defeated by supernatural means, and no battlefield slaughter is recorded,”** then the following battles or military actions can be considered “bloodless victories” or “zero‑casualty conflicts.”
### 1. Jehoshaphat Against the Alliance of Moab, Ammon, and Mount Seir
This is the most famous instance in the Bible of a “war without fighting.”
- **Reference**: 2 Chronicles 20
- **Background**: A coalition of three nations came to attack King Jehoshaphat of Judah. Jehoshaphat proclaimed a fast and prayed before the LORD, saying, “We do not know what to do, but our eyes are on you.” God answered through the prophet Jahaziel: “You will not need to fight in this battle. Stand firm, hold your position, and see the salvation of the LORD.”
- **Outcome**: As the people of Judah began to sing and praise, the LORD set ambushes against the coalition. The enemy armies turned on one another and completely destroyed themselves. The people of Judah did not draw a sword; they only went out to plunder the fallen, spending three days gathering the spoils. **This is the classic example of zero casualties on the Israelite side.**
### 2. The Victory at the Red Sea
Strictly speaking, this is not a “war” but an act of deliverance and judgment. From a military perspective, however, the Israelites went from being pursued to seeing their enemies destroyed without suffering any losses themselves.
- **Reference**: Exodus 14
- **Background**: Pharaoh’s army pursued the Israelites to the Red Sea. Moses stretched out his hand over the sea, and the LORD drove it back with a strong east wind, allowing the Israelites to cross on dry ground. The Egyptians followed them into the sea.
- **Outcome**: The LORD threw the Egyptian army into confusion, clogged their chariot wheels, and then commanded Moses to stretch out his hand again. The sea returned to its normal flow, drowning the entire army of Pharaoh. **Not one Israelite was harmed; they achieved complete deliverance without wielding a sword.**
### 3. The Fall of Jericho
In this battle, the inhabitants of Jericho were “utterly destroyed” (except Rahab and her family), so from the enemy’s side there were many casualties. However, from the perspective of **the Israelite soldiers**, this was a battle in which they did not engage in hand‑to‑hand combat; the walls fell simply by marching and shouting.
- **Reference**: Joshua 6
- **Background**: Joshua commanded the priests to carry the Ark of the Covenant, with seven priests blowing trumpets, while the people marched around the city once a day for six days. On the seventh day they marched around seven times. When the priests gave a long blast, the people shouted, and the walls of Jericho collapsed.
- **Outcome**: The Israelites entered the city and destroyed it. Although there were many deaths on the enemy side, **no Israelite is recorded as having been killed by enemy resistance during the taking of the city** (in stark contrast to the later battle at Ai).
### 4. The Destruction of the Assyrian Army (Hezekiah’s Time)
This is a classic example of a “battle fought by an angel.”
- **Reference**: 2 Kings 19, Isaiah 37
- **Background**: King Sennacherib of Assyria besieged Jerusalem and mocked the LORD. The prophet Isaiah declared that God would defend the city. That night, the angel of the LORD went out.
- **Outcome**: The angel struck down 185,000 men in the Assyrian camp. **Judah did not send out troops, nor did they engage in any kind of combat.** Sennacherib withdrew and was later killed by his own sons in his temple. For the people of Judah, this was a victory without having to fight.
### 5. Spiritual Warfare
If we move beyond physical battles, there are passages that describe heavenly conflicts involving no human deaths:
- **Daniel 10**: Daniel prays, and the angel Gabriel tells him that he was detained by the “prince of the kingdom of Persia” for twenty‑one days until Michael the archangel came to help. This is a spiritual conflict with no human participation.
- **Elisha’s Prayer (2 Kings 6:15‑23)**: The king of Aram sent a great army to surround Dothan. Elisha’s servant was afraid, but Elisha prayed that his servant’s eyes would be opened to see the hills full of horses and chariots of fire. Then he prayed that the Aramean army would be struck with blindness, and he led them into Samaria. When they arrived, he prayed again that their eyes would be opened. The king of Israel asked whether he should kill them, but Elisha said no; instead, he prepared a great feast for them. **This is one of the few instances in the Bible where an enemy army is neutralized without a single death** (and afterward the Aramean raiders did not return).
**Summary**:
If we strictly look for a war in which there were no deaths on either side, there is none recorded in the Bible. However, if we look for **victories where God’s people did not use weapons and suffered no casualties**, **Jehoshaphat’s victory over the coalition** (2 Chronicles 20) and **the deliverance at the Red Sea** (Exodus 14) are the most representative. **Elisha leading the Aramean army into Samaria and feeding them** (2 Kings 6) stands out as a remarkable example of overcoming an enemy without bloodshed.
