Source-derived summary

The Battle of Tassafaronga, sometimes referred to as the Fourth Battle of Savo Island or in Japanese sources as the Battle of Lunga Point (ルンガ沖夜戦; "Naval Battle of Lunga"), was a nighttime naval battle that took place on 30 November 1942 between United States Navy and Imperial Japanese Navy warships during the Guadalcanal campaign. The battle took place in Ironbottom Sound near Tassafaronga Point on Guadalcanal.

In the battle, a US force of five cruisers and four destroyers under the command of Rear Admiral Carleton H. Wright intercepted eight Japanese destroyers attempting to deliver food to their forces on Guadalcanal. The US destroyers waited four minutes after radar contact for permission to launch torpedoes and missed the optimal firing position; the torpedoes all missed, and the destroyers retired. The US cruisers opened fire and sank one destroyer. The muzzle flashes exposed the US cruisers' positions. Under the command of Rear Admiral Raizō Tanaka, Japanese destroyers quickly launched Type 93 "Long Lance" torpedoes, sinking one US cruiser and heavily damaging three others. The rest of Tanaka's force escaped undamaged but failed to complete the intended supply mission.

Rear Admiral Samuel J. Cox, director of the Naval History and Heritage Command, considers this battle and the Battle of Savo Island to be two of the worst defeats in US naval history, behind only Pearl Harbor.

Editorial reviewA strong contextual entry point for chronology, institutions and public events when official records are distinguished from later interpretation. The current lead gives the account dated anchors—1942—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Battle, Tassafaronga and naval can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the history & society register because the source frames it as 1942 naval battle between US Navy and Imperial Japanese Navy warships during the Guadalcanal campaign. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Aug 22, 2026. The linked authority identifier is Q1475679. The Library of Congress control number is sh96005011. Authority coordinates are -9.200, 159.833. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1942.

Critical limits

Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Compare institutional narratives with records created by participants and affected communities. Dates and formal titles are useful anchors, but not substitutes for context.
