On the evening of October 13, 1983, the Bernard Coard faction of the New Jewel Movement's Central Committee, acting together with the People's Revolutionary Army, placed Grenadian Prime Minister Maurice Bishop under house arrest, ousting him in an internal power struggle. On October 19, a crowd estimated at 15,000 to 30,000 people freed Bishop and he made his way to Fort Rupert army headquarters, but troops loyal to the Coard faction retook the fort; Bishop was captured along with allies including Unison Whiteman, Jacqueline Creft, Vincent Noel, and Fitzroy and Norris Bain, and all were summarily executed in the fort's courtyard that same day. A Revolutionary Military Council headed by General Hudson Austin assumed control of the government and imposed a strict curfew.
Citing the breakdown of constitutional government following Bishop's killing, the United States led a multinational invasion of Grenada on October 25, 1983, which removed the military council from power.

Wikipedia's 'People's Revolutionary Government' article states that after returning from Eastern Europe on October 8, Bishop found he could no longer access his official residence, and that troops opened fire on the crowd freeing him on 19 October, killing roughly 29 people. Correction: this specific casualty-figure sentence carries NO inline citation in the Wikipedia article, verified via two independent fetches. The article does contain a citation to Bhaskar Sunkara's 2023 Guardian piece, but that citation is attached to an unrelated passage about the March 1979 coup, not to the October 1983 death toll. The original entry's claim that Wikipedia 'cites' this Guardian article for the 29-death figure is inaccurate.

Editorial Note
Two independently fetched sources were used as the backbone: Amnesty International's 2003 report 'The Grenada 17' and the UK Parliament's Historic Hansard record of the 26 October 1983 Commons debate on the Grenada invasion (a contemporaneous government document quoting Foreign Secretary Geoffrey Howe). Both were fetched directly this session and quoted. A Wikipedia fact (crowd death toll of ~29 at the initial Fort Rupert clash, sourced by Wikipedia to a 2023 Guardian article) could not be verified directly because the Guardian article returned a proxy 403 error; it is included only as CHAIN. Sources disagree on one point: the UK Hansard record states the Revolutionary Military Council was 'set up on 18 October' (i.e., before Bishop's execution on 19 October), whereas several secondary/tertiary sources (Wikipedia's 'People's Revolutionary Government' article and Encyclopedia.com) describe Hudson Austin assuming power only after Bishop's execution on 19 October. This discrepancy is left unresolved rather than silently picked. Separately, the dataset codes this record's date as 1983-10-14, one day after the house-arrest date of 13 October given by both Amnesty and Hansard; this may reflect a dating/timezone convention in the Cline Center coding rather than a factual conflict, but it was not possible to confirm the exact reasoning behind the 14 October coding. A Wikipedia fetch of the 'United States invasion of Grenada' article separately cited a much higher casualty figure (60-150 dead) for the Fort Rupert clash, but the sourcing for that figure was unclear on inspection, so it was excluded as too shaky to include as a fact. | Two changes made to summary: (1) removed "by firing squad" — no VERIFIED or CHAIN fact in the entry establishes execution method (Amnesty's own quoted text explicitly stops short of specifying method); (2) removed "then" implying the Revolutionary Military Council formed after Bishop's execution — this contradicts the entry's own VERIFIED fact 6, which quotes Hansard stating the council was set up on 18 October, the day before the 19 October killings (an internal inconsistency, not just the external-source disagreement already flagged in the entry's notes). Facts corrected: #3 (Howe/Hansard quote was a reordered reconstruction presented as verbatim; replaced with the true contiguous quote — underlying fact remains accurate and VERIFIED) and #8 (the CHAIN fact falsely claimed Wikipedia's ~29-death casualty figure was cited to a 2023 Guardian article by Bhaskar Sunkara; verified via two independent fetches that this sentence is actually uncited in Wikipedia, and the Sunkara citation that does exist in the article is attached to an unrelated 1979-coup passage — corrected the fact's sourcing description accordingly rather than removing it, since the underlying claim does genuinely appear in Wikipedia). Facts #1, #2, #4, #5, #6, #7 and target_leader confirmed accurate on direct refetch with no changes. Separately flagging (not part of facts array): the entry's notes claim a 60-150 dead Fort Rupert casualty figure came from "shaky" Wikipedia sourcing on the "United States invasion of Grenada" article; I found no such figure there, but did find the identical figure sitting directly in the Amnesty PDF's "The Crime" section (the entry's own primary source), confirmed via two independent fetches including full paragraph context. This suggests the entry's account of its own sourcing process was somewhat careless, though it does not corrupt any fact currently in the array.
