On April 27, 1965 the loyalist counteraction broke the constitutionalist provisional government installed two days earlier in Santo Domingo. General Wessin y Wessin's forces, some 1,500 troops with armor from San Isidro, captured the Duarte Bridge and pushed against the rebel held center, while a second column attacked the western suburbs and loyalist aircraft and the vessel Mella bombarded rebel positions; with the constitutionalists reeling, provisional president Jose Rafael Molina Urena and Colonel Caamano asked US Ambassador Bennett to intervene to stop the air attacks and broker a solution, and were refused. Dismayed, Molina Urena relinquished the provisional presidency that day and took refuge in the Colombian embassy, joining other rebel leaders seeking asylum in foreign missions, while command of the constitutionalist cause passed to Caamano, whose fighters then threw back the armored thrust at the bridge.

Constitutionalist provisional president Molina Urena and Colonel Caamano asked the US ambassador for intervention to stop the Dominican Air Force attacks on constitutionalist held areas and were refused; utterly dismayed by the rejection, Molina Urena relinquished his position as provisional president to Colonel Caamano, while at San Isidro the loyalist generals chose Air Force Colonel Pedro Bartolome Benoit to head a new loyalist junta.

In the early morning of April 27 over a thousand foreign civilians were evacuated from the Embajador Hotel to US ships; later that day 1,500 loyalist troops supported by armored cars and tanks marched from the San Isidro base, captured Duarte Bridge, and took position on the west bank of the Ozama, a second force of 700 attacked the western suburbs, and when Wessin y Wessin ordered his armored units across the bridge into the city center the tanks became bogged down in the narrow streets and were destroyed, abandoned, or captured by armed civilians.
A US Defense Department report recorded that after the April 26 loyalist bombing of rebel held areas the rebel government head Molina took refuge in the Colombian embassy, other early rebel leaders sought refuge in foreign embassies, and extremist and communist elements moved into the rebel ranks as arms were distributed to thousands of civilians.

The loyalist junta's inability to finish the fight and the collapse of order led President Johnson to order intervention: initial US action was limited to evacuating citizens, but from April 28 US forces landed in strength under Operation Power Pack, eventually 42,000 troops, in a deployment that, though ostensibly neutral, aided the anti-Bosch forces, and the civil war ran to the ceasefire and provisional government of September 1965 with elections in 1966 won by Balaguer.

Editorial Note
Paired record care: this record is the loyalist countercoup phase, the deposition of the constitutionalist provisional government of Molina Urena on April 27, and must not be conflated with the April 25 arrest of Reid Cabral carried in the companion record. Interpretation is stated openly: the dataset's deposed leader with fled the country on April 27 best matches Molina Urena's same day resignation and flight into the Colombian embassy under the loyalist assault, the reading adopted here with the alternatives documented. The military outcome was mixed, the armored thrust failing at the bridge even as the provisional government dissolved, and neither faction controlled the state when US forces landed April 28. Sequencing sources differ on minor points (the papal nuncio ceasefire is dated April 29 in one account and April 30 in another); these are noted, not resolved.
Cross-Reference
Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
Identifiers for finding this same event in the other datasets:
Coup Atlas research identifies the target as: Provisional president Jose Rafael Molina Urena, who relinquished office on April 27, 1965 after the US ambassador refused help against the loyalist air and armor assault, and took refuge in the Colombian embassy; he was not physically harmed..
Baseline coding: Incumbent executive removed from power. Recorded leader fate: deposed; fled the country. The baseline file does not name individual targets; researched names are kept in a separate layer.
