Comandos trial: Court revises temperature data and 'zero test' interruption facts

Two recruits, Dylan da Silva and Hugo Abreu (both 20 years old), died during the training exercise; multiple other trainees suffered serious injuries requiring hospitalization.
The decision to halt came only after consulting medical staff and the regiment commander
The court's revised findings show Lieutenant Colonel Mário Maia took steps to address the dangerous conditions before the exercise was suspended.

Court documented extreme heat conditions (40.2°C average) on September 4, 2016, when recruits Dylan da Silva and Hugo Abreu died during the Comandos training exercise in Alcochete. The court found that Lieutenant Colonel Mário Maia consulted medical staff and the regiment commander before deciding to interrupt the 'zero proof' exercise due to heat, dehydration, and exhaustion among trainees.

  • Dylan da Silva and Hugo Abreu, both 20, died during Comandos training on September 4, 2016
  • Temperature recorded at 40.2°C average, 40.9°C maximum in Pegões that day
  • 19 defendants charged; prosecution seeking 2-10 year sentences for five of them
  • Court revised facts regarding temperature data and the decision to interrupt the 'zero proof' exercise

A Portuguese court revised key factual findings in the Comandos recruits death trial, including temperature records and the decision to halt the training exercise, with defense counsel claiming the changes favor their clients.

A Portuguese court has revised its factual findings in one of the country's most scrutinized military trials—the case surrounding the deaths of two young recruits during a Comandos training exercise five years ago. On Tuesday, the judges notified all parties through the court's electronic system that they were altering key facts from the prosecution's original accusations, including precise temperature readings from the day and the sequence of events that led to the suspension of the training.

Dylan da Silva and Hugo Abreu, both twenty years old, died on September 4, 2016, during what is known as the "zero proof"—the first test in the elite Comandos course, held in Alcochete near Lisbon. The heat that day was severe. According to the court's revised findings, the meteorological station at Pegões recorded an average temperature of 40.2 degrees Celsius, with highs of 40.9 and lows of 39.1. At Coruche, the readings were slightly lower but still extreme: 38.3 average, 39.6 maximum, 37.5 minimum. Beyond the temperature itself, the court found that trainees were rationing water, pushing through demanding combat instruction exercises, and showing signs of profound exhaustion and dehydration. Several recruits had already been moved to the medical tent, including one named Ailton Spínola, who required intravenous fluids.

The revised facts paint a picture of escalating concern among those running the exercise. Lieutenant Colonel Mário Maia, who directed the training, noticed that a large number of recruits from two groups were struggling to complete their assigned tasks. He called over the medical officer, Miguel Domingues, who assessed the situation and determined that at least one trainee needed immediate care. Later, after lunch, Maia telephoned the Comandos Regiment commander, Dores Moreira, to alert him to the dangerous heat. Moreira suggested altering the schedule for the following day. The court's revised account emphasizes that the decision to halt the exercise came only after Maia consulted both Domingues and another officer named Rui Monteiro—the doctor reported he had multiple trainees in the medical tent and lacked resources to support further instruction, while Monteiro advised against continuing given the demands of the planned exercises.

The trial involves nineteen defendants—eight officers, eight sergeants, and three enlisted men, most of them instructors. The prosecution has sought prison sentences ranging from two to ten years for five of them, charging them with abuse of authority resulting in serious physical harm. The accusation states they acted with "manifest disregard for the grave consequences" they inflicted. Beyond the two deaths, multiple other recruits suffered serious injuries and required hospitalization.

Alexandre Lafayette, the defense attorney for Maia and sergeant-instructor Ricardo Rodrigues, told reporters that the court's revisions are favorable to his clients and that he will not request additional evidence or further proceedings. He emphasized that the revised facts support the actions his clients took, particularly Maia's intervention to stop the exercise. The attorney representing the families of the two dead recruits, Ricardo Sá Fernandes, has not yet commented publicly on the changes.

The court's decision to revise these facts came after technical recording problems forced a postponement of the verdict reading on Monday. Before adjourning, the judges informed all parties that they intended to communicate the factual amendments and asked whether they could do so electronically. No one objected. Now, all parties have ten days to respond and indicate whether they wish to request additional evidence or procedural steps. The verdict itself remains pending, and the revisions suggest the court's understanding of what happened that day—and who bears responsibility—may differ in important ways from what the prosecution originally alleged.

The court found that the decision to interrupt the exercise came after Lieutenant Colonel Mário Maia consulted the medical officer and another officer, both of whom advised against continuing given the conditions and the demands of the planned instruction.

Why would a court revise its factual findings this late in a trial? Doesn't that seem unusual?

Model

It happens when judges want to ensure the record is precise before they issue their final verdict. They're not changing the law or the charges—they're clarifying what actually occurred on the ground. In a case with this much scrutiny and this much at stake, getting the facts right matters enormously.

Inventor

And these revisions—the temperature data, the phone call to the commander—they help the defense?

Model

According to the defense attorney, yes. Because they show Maia was actively monitoring the situation, consulting medical staff, and taking steps to address the danger. It's the difference between someone who ignored warning signs and someone who saw them and acted.

Inventor

But two people still died. Does that change?

Model

No. The deaths are the foundation of the entire case. What changes is the court's understanding of whether those deaths resulted from negligence and disregard, or from a situation that deteriorated despite reasonable precautions. That distinction determines guilt.

Inventor

The prosecution wanted sentences up to ten years. Do you think these revisions will affect that?

Model

Almost certainly. If the court finds that the exercise was halted based on medical advice and consultation with superiors, it's harder to argue reckless disregard. The prosecution will have to make its case within a different factual framework.

Inventor

What happens now?

Model

The families and prosecutors have ten days to respond. They can request more evidence, challenge the revisions, or accept them. Then the court issues its verdict. The real test comes when the judges explain their reasoning in writing.
