Structurally, this is one of the stronger highlights in the insight. Four slides, two battles, a treaty, and a closing line — 'La Matanza marks where the Guanches won. La Victoria marks where the Spanish won. Los Realejos marks where it ended. You can drive between all three in twenty minutes' — that earns its place. The chronology is clean and the cape-swap detail is exactly the kind of specificity the brand rewards.
The issues are surgical. One factual error (soldier count: 2,000+ vs ~1,120), one literal typo (he victory), a repeated awkward phrasing ('in translation the slaughter' / 'in translation he victory'), space-before-colon drift caught elsewhere in the insight but clean here, and a cross-highlight terminology mismatch: the Cities siblings use Alonso Fernández de Lugo on first mention while this highlight only ever uses the surname. None of these are rewrite-the-slide problems — they're a single editorial pass.
The 80% loss figure stays dramatic either way; if anything, ~1,120 soldiers losing 80% is more powerful than 2,000+ losing 80%, because 900 dead in one ravine reads more immediate than a rounded five-figure estimate. Fix the number, keep the drama.
Optional recommendations
Optional — not slide-level. Three directions the highlight could grow into, none urgent:
Tie the closing line to a concrete anchor. The 'drive between three towns' beat is the highlight's best line but drops the reader without a pointer. A guide-note on slide 4 — a mirador, a plaque, or the Mirador de Humboldt if it sees all three valleys — would give Pierre and Clara somewhere to stand.
Bridge to Santa Cruz's founding. The Festivals highlight mentions Fernández de Lugo planting a wooden cross at Añazo on 3 May 1494. This highlight could close one of its slides with 'Nine days earlier he had planted a cross on the beach at Añazo. That became Santa Cruz.' — strengthening the insight's interconnection.
Bentor's leap needs one line of weight. Slide 4 opens with a suicide and moves on. For Pierre specifically, one beat — that Bentor's jump became the Guanche symbol of refusal — would stop it reading like a bullet point.
Leave these to the author's call. They're lens-driven, not rubric-driven.
Research
Disputed claim. From /tmp/island-rites-rituals-research.json:
Claim:Fernández de Lugo led more than 2,000 soldiers into the ravine of Acentejo. Finding: Wikipedia's article on the First Battle of Acentejo gives the Spanish force as approximately 1,120 soldiers, not more than 2,000. Source:en.wikipedia.org/wiki/First_Battle_of_Acentejo
Verified claims (from same research JSON, high confidence):
The First Battle of Acentejo occurred in May 1494 in a ravine in the north of the island. Fernández de Lugo escaped by swapping his red cape for a common soldier's. — Wikipedia
The Spanish lost 80% of their force at La Matanza. — Wikipedia
Persona reactions
Agreement. All three personas converge on the closing line ('three towns, twenty minutes') as the highlight's strongest beat — and all three flag that the typo on slide 3 is disproportionately corrosive. It's a ⚠️ in isolation but a ❌ for trust on a paid guide.
Conflict. Pierre wants more historical texture (the patrilineal correction, Bentor's symbolic weight) while Lena & Théo want less history and more 2026 hooks (viewpoint, meal, festival). Clara sits between them, asking for a navigational link out to a day trip or the Santa Cruz founding, not more prose.
Persona-driven fixes.
Fix the typo and the 'in translation X' phrasing on both slides 2 and 3 (biggest trust hit, smallest effort).
Correct 'more than 2,000 soldiers' to ~1,120 per Wikipedia — the 80% loss is more dramatic against the smaller force, not less.
Use Alonso Fernández de Lugo on first mention to align with the cities siblings; subsequent references stay as Fernández de Lugo.

LA MATANZA

LA MATANZA
textBody
Current
In May 1494 the Spanish commander Fernández de Lugo led more than 2,000 soldiers into the ravine of Acentejo in the north of the island. The Guanches ambushed them from the slopes above. The Spanish lost 80% of their force. The Spanish commander escaped by swapping his red cape for a common soldier's. The town built on that battlefield is called La Matanza, in translation the slaughter.
Proposed
In May 1494 the Spanish commander Alonso Fernández de Lugo led around1,120 soldiers into the ravine of Acentejo in the north of the island. The Guanches ambushed them from the slopes above. The Spanish lost 80% of their force. FernándezdeLugo escaped by swapping his red cape for a common soldier's. The town built on that battlefield is called La Matanza—literally, the slaughter.
Why. Four targeted edits. (1) 'more than 2,000 soldiers' → 'around 1,120 soldiers' per Wikipedia; 80% of ~1,120 reads more visceral than 80% of a rounded 2,000+. (2) First mention becomes Alonso Fernández de Lugo to align with the Santa Cruz and La Laguna sibling highlights. (3) Second reference drops to 'Fernández de Lugo' and replaces 'the Spanish commander' — we already know he is. (4) 'in translation the slaughter' → '— literally, the slaughter' — reads natively in English.

LA VICTORIA

LA VICTORIA

Current
Fernández de Lugo returned with a rebuilt army and chose open ground near Aguere, now La Laguna, where his cavalry had room to move. Bencomo, the mencey of Taoro and the most powerful king on the island, made the fatal error of engaging on flat terrain. He was killed in the battle alongside his brother Tinguaro. The town founded on the site of the final Guanche defeat is called La Victoria in translation he victory.

Why. Fixes the literal typo (he victory → the victory, missing t) and mirrors slide 2's new construction ('— literally, the X'). Rest of the slide is untouched — Bencomo, Tinguaro, the cavalry-on-flat-ground explanation all land well.

Bentor, Bencomo's son, threw himself from the cliffs at Tigaiga rather than surrender. On 25 July 1496 the remaining menceyes signed the Treaty of Los Realejos. They accepted Christianity and Spanish rule. La Matanza marks where the Guanches won. La Victoria marks where the Spanish won. Los Realejos marks where it ended. You can drive between all three in twenty minutes.
