Before dawn on 14 July 1978, soldiers taking part in an exercise in the El Garrobillo–Pinilla area of Murcia reported a group of lights that appeared to accompany them back toward their camp. The released Spanish military file is catalogued under Mazarrón as dossier 780714. Its surviving evidence is a short information note quoting a captain’s report, followed by a much later assessment for declassification.
The account contains striking claims about low height, movement and red illumination. It also has a clear documentary limit: the later reviewer states that no further case material was held beyond the transmitted note. This is therefore a report with insufficient supporting evidence for a physical identification, rather than a demonstrated encounter with an extraordinary craft.
An exercise before dawn
The note says the unit was conducting several days of field exercises. During the night of Thursday 13 July, a detachment was ordered to carry out a practice raid against another company bivouacked in the Rambla de Pinilla area. The observation occurred on the return journey, between about 04:00 and 06:00 local time on the 14th.
The distinction between the night’s starting date and the following morning matters. The catalogue’s incident date is 14 July 1978. The later administrative transfer and declassification do not create a second event. Nor should the exercise’s several-day duration be treated as several days of reported lights: the document describes this particular return journey.
The captain’s account was quoted in a September 1978 intelligence note. It was subsequently transmitted into the air-force review system in 1993. The released file therefore gives access to an early report through a chain of official copying. It is not a newly conducted interview with every soldier, and the later summary is not an additional independent witness.
The reported group of lights
The quoted description centres on a red light that sometimes went out. Two white lights with a slight greenish tint appeared intermittently. The longer 1978 text also mentions four further white lights appearing much less often without a fixed formation. The later summary abbreviates this description. Keeping the fuller note in view prevents an apparently simpler three-light configuration from replacing the original account.
The soldiers first watched the lights for approximately fifteen minutes opposite the Rambla de Pinilla. Their distance was not defined. They reportedly moved from side to side. Later, near a kilometre marker on the return route, the group appeared stationary above the road at an estimated eight to ten metres.
When the men approached, the lights seemed to move ahead. The report says they went around obstacles such as houses or rises in the ground and returned to a position in front of the party. They were said to accompany the soldiers toward the bivouac, with height estimates ranging from four to thirty metres.
These figures and movements are reported perceptions. The surviving material does not establish surveyed range, calibrated angular measurements or a verified object size. In particular, the file gives no sufficiently resolved physical outline to justify drawing a triangular craft around several lights. Multiple-lights is the supported feature tag; triangle is not.
Silence and illumination
The note describes the phenomenon as completely silent. It also says a red light illuminated a wall of a reservoir. That is more specific than a generic light in the sky, but the claim remains within the same quoted account. The release supplies no independently photographed illuminated wall or later measured lighting reconstruction.
No occupants, communication, landing or water entry are described. A reservoir appearing in the geographical account does not make this an underwater-object case. Likewise, reported low height should not be converted into a landing claim when the source records no ground contact. These distinctions keep the catalogue useful without giving the report features its witnesses did not establish.
The following night’s check
The unit reportedly inspected the area the next night and found nothing abnormal. A meteorological-station antenna was noticed, but those involved maintained that it could not account for their observation. The note preserves that rejection. It does not describe a controlled comparison of the antenna’s appearance from every relevant position under identical conditions.
The inspection is consequently a real follow-up, but not a demonstrated solution. Finding nothing unusual on the next night does not erase the report. Equally, the soldiers’ insistence that the antenna was unsuitable does not independently eliminate every ordinary light, perspective effect or mistaken distance estimate. The available record is too limited to establish such exclusions.
What survived for review
The declassification summary explains that information from the army’s intelligence service had been copied into a note and later sent to the reviewing air command. The document index lists that note’s two pages. Unlike a large inquiry containing separate interviews, radar sheets and technical reports, this release has a narrow evidential base.
The summary adds no confirmed explanation. Its recommendation concerns whether the paperwork still needed classification. The declassification stamp is dated 31 May 1998, and the library receipt is from June. These administrative decisions concern access to the record. They do not certify either an alien vehicle or an identified ordinary cause.

A geographical qualification
The catalogue and report call the case Mazarrón and place El Garrobillo in that municipal setting. Modern geographical sources use Garrobillo and Pinilla y Garrobillo for localities in the Lorca–Águilas area. Lorca’s official place directory includes Pinilla y El Garrobillo, while GeoNames lists Garrobillo under Águilas. The historical label should not be copied into a falsely precise modern incident address.
Approximate map area: 37.49, -1.50, a broad Garrobillo-area reference rounded from the GeoNames locality coordinate. It is a regional reference for the reported exercise area, not the exact road kilometre marker, reservoir, bivouac or a residence. The old grid references have not been used to invent a precise modern encounter point.
Assessment and sources
The case is insufficient evidence because the underlying observation survives through a short quoted report without the measurements or independent records needed to resolve its identity. The next-night check did not find a cause. The source supports documenting what the soldiers reported, but not deciding that an unknown vehicle demonstrably followed them.

The broad map reference comes from GeoNames’ Garrobillo locality record. The naming qualification is checked against Lorca’s official street and population-entity directory. Sources and image reuse terms checked 13 November 2026.
