I don't normally go in for deathfics, but this is quite possibly the most beautifully poignant H/D deathfic short piece I have read.

Title: Last Regret
Author: Kali
Rating: I guess it should be R for, ya know, the death
Summary: Harry finds Draco dying on a battlefield, and talks to him a little, finding out that Draco has just one regret
Warnings: This is a DEATHFIC! Draco dies. Don't read it if you don't like that, and don't flame me if you chose to ignore this warning
