[Li Nalas tells Sisko the story about how he came to fame]

Li Nalas:
...We made our way to a ridge overlooking a small lake. As I was the only one still carrying a phaser, I went on ahead to scout for the enemy. Halfway down the embankment, I slipped, went sprawling on my back down to the edge of the lake, just as a huge Cardassian emerged from the water. He must have just finished bathing. He stood there, frozen in surprise, dressed only in his underwear, shivering in the cold. I lay there, looking up at him, too stunned to even move, and it was only when he reached for a phaser rifle that was lying across his clothes on a nearby rock, that I realized that I was still holding my own phaser, and I shot him. His body fell on top of me, and that's how my companions found us a moment later.
