On Easter Monday, 1917, the first day of the Arras Offensive, he paused for a moment to fill his pipe. A shell passed so close to him that the blast of air stopped his heart; he died without a mark on his body.

Thomas was an astonishing thing, an established literary critic who suddenly morphed into a great poet. All his poems were written in the three years before he died, and he kept getting better. The Other is hauntingly good: http://www.poetryfoundation.org/poem/239754. WWI famously killed many poets, but I wish Thomas hadn't been one of them. He had pure English in his veins, and I like him better than Frost.
