This is a poignant story, and as others have already said here it reflects the reality and pity of war, which always deserves a moment or two of reflection. A UK newspaper also has an item of this, which can be seen at: http://www.dailymail.co.uk/news/article-2158303/Rare-intact-skeleton-British-soldier-site-Waterloo-battlefield-musket-ball-felled-ribs.html
One perhaps for the amateur detectives, and I do not rank myself as one of these! According to the above article, the unfortunate 'late British soldier' - if indeed he was - was young and short, only just over 5 feet. Makes you wonder not only about how and when he died, but when he was buried. It is very easy to imagine that he was killed during the battle, probably severely wounded and taken to the rear but died before he could be attended to. Following the battle, with the Allies in possession of the battlefield, this corpse may then have been buried where he lay. But there must have been many others, especially if he had been taken back to some sort of rudimentary field dressing station. Will the new car park reveal more bodies perhaps?
