Primary text read
Civitas read the ancient or primary text for at least one figure on this card. Other figures may still be Wikipedia-compiled and are labelled.

naval battle · 26 or 27 September 480 BCE

Battle of Salamis (480 BCE)

Decisive trireme battle in confined waters; standard example for naval warfare and for Athenian sea power.

Evidence: Primary text read Draft estimate

What the record says

  • Note Date 26 or 27 September 480 BCE; outcome: Greek victory.
  • Unverified (Wikipedia-compiled) Wikipedia-compiled (stub): Greek fleet 371-378 ships; Greek losses ~40 ships, Persian losses ~300 ships. Ship counts derive from Herodotus/Aeschylus traditions and are contested.
  • Primary text PRIMARY-SOURCE figures: Herodotus (Rawlinson transl., vol. 4, read 2026-10-12): 7.89 Persian triremes "in all twelve hundred and seven" at the muster (before storm losses); 8.48 Greek fleet "without counting the penteconters, three hundred and seventy-eight"; 8.89 Ariabignes, a Persian fleet commander, killed, "of the Greeks there died only a few", most barbarian dead drowned. Ancient claims, not measurements; Rawlinson's own note flags the 378 vs 366 problem.

Confidence. low-medium (ship counts contested).

Evidence: Primary text read Draft estimate

What the record says

  • Primary text PRIMARY-SOURCE (read 2026-10-12, Arrian transl. Chinnock), Anabasis 2.8: Darius sent "about 30,000 of his cavalry and with them 20,000 of his light-armed infantry" across the Pinarus; placed "the 30,000 Greek mercenaries" against the Macedonian phalanx with "60,000 of the men called Cardaces" beside them; "The whole of the army with Darius was said to number about 600,000 fighting men." Reported claim ("was said").
  • Primary text PRIMARY-SOURCE (read 2026-10-12, Arrian transl. Chinnock), Anabasis 2.10: "Here fell Ptolemy, son of Seleucus ... besides about one hundred and twenty other Macedonians of no mean repute." Notable dead only; not a total Macedonian loss figure.
  • Primary text PRIMARY-SOURCE (read 2026-10-12, Arrian transl. Chinnock), Anabasis 2.11: Darius fled in his chariot, left it at rough ground with his shield, mantle and bow; killed Arsames, Rheomithres, Atizyes, Sabaces (viceroy of Egypt), Bubaces, "besides about 100,000 of the private soldiers, among them being more than 10,000 cavalry"; the camp taken with Darius's mother, wife and infant son; fought "in the month Maimacterion, when Nicostratus was archon of the Athenians".
  • Primary text PRIMARY-SOURCE (read 2026-10-12, Arrian transl. Chinnock), Anabasis 2.12: the next day Alexander, wounded "in the thigh from a sword", visited the wounded and buried the dead.
  • Note Not used: Chinnock's footnotes citing Curtius, Diodorus, Justin and Plutarch (not independently read).

siege · January-July 332 BCE

Siege of Tyre (332 BCE)

Canonical ancient siege combining a mole, siege towers and naval blockade; a model case for concept-siege-warfare.

Evidence: Primary text read Draft estimate

What the record says

  • Unverified (Wikipedia-compiled) Dates January-July 332 BCE; outcome: Macedonian victory (Wikipedia infobox).
  • Primary text PRIMARY-SOURCE figures: Arrian, Anabasis 2.24.4-5 (English translation hosted on johndclare.net, read 2026-10-11): about 8,000 Tyrians killed in the final assault; Macedonian losses in the assault included Admetus and about 20 royal guards, and about 400 Macedonians died in the whole siege; about 30,000 Tyrians and foreigners enslaved; those who fled to the sanctuary of Heracles were granted amnesty.
  • Unverified (Wikipedia-compiled) Other accounts (Diodorus, Curtius; not read by me) reportedly add ~2,000 crucified; Wikipedia compiles 6,000-7,000 killed + 2,000 executed (stub). Treat Arrian as a single ancient claim, not a measurement.

Confidence. medium (narrative); numbers = ancient claims read in primary text.
