"[on feeling down] It is quite understandable. It's a very natural reaction. But one day, in a week, a month, a year, on that day when God willing, we all return to our homes again, you're going to feel very proud of what you have achieved here in the face of great adversity. What you have done, should be, and I think will be, an example to all our countrymen, soldier and civilian alike. You have survived with honour, that and more: here in the wilderness, you have turned defeat into victory. I congratulate you. Well done."
