I've travelled fairly extensively in Turkey, but never to Gallipoli so can't really help with this one I'm afraid. Most towns and cities in Turkey prominently display statues or large busts of Ataturk, who is still held in high regard - and rightly so. He was a brilliant military and civilian leader, with a gift for attempting the seemingly impossible and succeeding. He even organised the change in Turkey's alphabet from Arabic to European script!
Ataturk's mausoleum in Ankara, as well as being his final place of rest, is also a museum to his life, and houses many personal possessions. The guard of honour, usually comprises members of the navy, army and airforce, and their turn-out is excellent.
Britain's Winston Churchill is said to have detested Ataturk, probably because he gave the allied forces a 'bloody nose', and once said of him 'Turkey is governed by a drunk', to which Ataturk, who had a great liking for Turkish arak readily agreed! There is a common saying in Turkey which goes 'without Ataturk, Turkey would be like Afghanistan'.
