March was the tactical peak: three of four documented U.S. tactical victories in the Iran war fell in one month

Asked:

“The number of US victories in the war with Iran by month.”

No authoritative month-by-month ledger of “victories” exists, so this report counts conservatively: a victory is one distinct, dated U.S. combat action reported to have achieved its immediate tactical objective, with cumulative battle-damage updates and duplicate reports removed. On that basis the reviewed web evidence supports 4 tactical victories from the war’s start on February 28 through August 2026 — 1 in February, 3 in March — plus one separate campaign-level victory declaration in April. Units are distinct actions per calendar month.

The single February victory is the war’s opening: the Feb. 28 first-wave strikes of Operation Epic Fury, reported to have suppressed Iranian air defenses and hit leadership targets in the opening hours — en.wikipedia.org

All three March victories were naval or maritime: the sinking of IRIS Dena by USS Charlotte (Mar. 4), two warships destroyed dockside at Chabahar (Mar. 5), and the Kharg Island military-target raid — homelandsecuritynewswire.com

The Kharg Island raid is counted once despite two dated reports (Mar. 11 and Mar. 14) that describe the same target set of 90+ military sites — asiatimes.com / todayville.com

April’s marker is a declaration, not an engagement: officials called the campaign a “total” victory, citing 13,000+ targets struck, over 90% of Iran’s regular naval fleet sunk and about 80% of its air defenses destroyed — politifact.com

The qualifying events

Month	Date	Event	What the reporting says	Type	Source

Method: live-web research conducted September 1, 2026, covering the U.S.–Iran war from its February 28, 2026 start through August 2026. Built from 33 extracted candidate records across three result sets; most were cumulative battle-damage snapshots, duplicate reports of the same action, or undated campaign summaries and were excluded, leaving 4 distinct dated tactical victories and 1 campaign-level declaration. A number measures distinct qualifying actions per calendar month. “Victory” is judgment-dependent; sources mix official claims and secondary reporting, so this is a conservative reproducible count, not an official battle register. No additional distinct, exactly dated tactical victories were confirmed for April–August.
