Friends around the globe have sent samples from places as diverse as Waterloo , site of Napoleon 's 1815 defeat , and Gaugamela , east of modern-day Mosul in northern Iraq , where Alexander the Great defeated Darius III of Persia in 331 B.C. The dirt goes into 65 iron cannonball-size boulders that Mr. Joyce has forged as time capsules of human conflict .
