We were applying tourniquets and compressive bandages and treating collapsed lungs.

There was also the human aspect where we were talking to the victims to explain to them what we were doing. Saying, “I’m a doctor, my name is Matthieu, we’re going to get you out of here.”

I remember the looks in their eyes, the words of some of the victims.

One of the first things I did when I got to the pit was to shout — I have a loud voice that carries — “All the victims who can move on their own, please stand up and come over here.”

Unfortunately, all those who could move had either already fled or had hidden.

At around midnight, people heard the cops knocking at the door. People were asking, “Should we open the door?” The terrorists had gone to the bathroom where people were hiding and pretended to be special forces. So it was not obvious what to do.

They opened the door, and we left to go through the exit near the stage. I saw the cops, and one was young and he looked so scared. I took one girl with me and told her to put her hands on her eyes. I walked through the central area near the stage, and it was war. Young people had been dancing two hours earlier, but now there was blood everywhere. It was horrible.

I arrived [at Police Headquarters] to see televisions screens with images of the video protection [security cameras] of Paris that are connected to the police and that have close-ups of what was happening in different places.

Then there was this whiteboard, and it had all the sites listed on it and then columns for absolute emergency, relative emergency and dead.

It seemed surreal to me. There were perhaps more people in the column “deceased,” at least at the beginning, than the other columns.
