What "won" means in the Alexander sources
Alexander's career runs from his accession in 336 BCE through his death in Babylon in 323 BCE. The campaigns cover the Balkans, Asia Minor, the Levant, Egypt, Mesopotamia, Iran, Central Asia, and the Indus region.
Arrian, drawing heavily on Ptolemy and Aristobulus, is the usual starting point for battle narratives. Plutarch's Life of Alexander and Diodorus add color and sometimes different numbers. None of them hands you a modern win-loss box score. They describe set-piece battles, sieges, pursuits, and local revolts.
Live search results split the viral question. Some threads repeat a popular modern tally of about 19 battles and 12 sieges. Academic and encyclopedia pages more often stress the undefeated field record and the four major pitched battles against royal or satrapal armies. The English Wikipedia article Wars of Alexander the Great (page checked 25 October 2026) even publishes a long victory table that mixes battles and sieges from Chaeronea onward.
Major field battles usually counted as victories
The table below lists the four pitched battles most often named when people ask how many big fights Alexander won against imperial or royal armies. Years follow common textbook dating. Results follow the standard narrative outcome (Macedonian victory).
| Battle | Year (BCE) | Main opponent | Result in standard accounts | Notes |
|---|---|---|---|---|
| Granicus | 334 | Persian satraps in Asia Minor | Macedonian victory | Opening battle of the Asian campaign |
| Issus | 333 | Darius III | Macedonian victory | Darius fled; family captured |
| Gaugamela (Arbela) | 331 | Darius III | Macedonian victory | Often treated as the decisive Persian defeat |
| Hydaspes | 326 | King Porus (Paurnava) | Macedonian victory | Costly win; Porus kept as a vassal in many tellings |
Under that narrow field-battle rule, the headline number is four major named victories against royal or satrapal armies, with no matching major defeat in the same category. Encyclopaedia Britannica and similar references also stress the undefeated field record rather than a single universal total of every fight.
Sieges and other actions change the count
Tyre (332 BCE) is the classic example of a siege that was strategically huge and tactically brutal, yet is not a "battle" in the open-plain sense. Gaza fell after another hard siege in the same year. Thebes had already been destroyed in 335 BCE when Alexander crushed the Greek revolt before crossing to Asia.
If a quiz wants "battles won" and the teacher means every named combat action, the tally rises quickly. That is where the roughly 19-and-12 style counts come from: they fold sieges and lesser engagements into one career log. Different atlases disagree on what to include, and some catalogues explicitly warn that an entry count is not a claim Alexander personally fought that many discrete battles.
Gaugamela is also called Arbela in some older English works because the fight sat near that city. Same battle, two labels. For another page on this site about how military reputations get simplified, see Erwin Rommel. For fortress memory from a later century, see the Maginot Line.
How to answer the search query cleanly
Best short answer: Alexander is presented as undefeated in major pitched battles; the Persian and Indian field set usually cited is Granicus, Issus, Gaugamela, and Hydaspes.
Best careful answer: say which list you are using (four great pitched battles versus a broader battles-and-sieges catalogue), cite Arrian or a modern reference for each row, and do not invent a fake ancient official total.
Cold War deterrence ideas such as mutually assured destruction belong to a different era; use that page when you are comparing how later powers avoided direct great-power battle, not when you are counting Macedonian engagements.
