Once on Chunuk Bair

Am I getting sentimental in my old age? The other morning, just after I woke up, I felt the need to check some geographical details with respect to the Gallipoli peninsular. I was trying to understand the precise relationship between Lone Pine, Chunuk Bair and the Nek. Also, which were the troops that took the first, and the second, though only briefly, and were slaughtered in their hundreds at the third site. Was it simply the sound of the names in my head, on my tongue, that blurred my eyes, so that I could not read the words on the page? It was strange to lie back on the pillows and feel the tears running down my cheeks - why?
