ANZAC or Anzac?

[Dianaa]

Given that the name was apparently coined by a signaller, it would have been transmitted by morse code which does not contain case in the letter/numeral codes. Similarly newspaper reports from the front would go over the wire and be formatted into case sensitive text by the typesetters back in Australia using regular English language conventions. These reports can only be considered secondary sources in this context.

While I agree Mike's original post mentioned the date of June 1915, two months after the landings at what became Anzac Cove and I've commented on that earlier date in above posts. I still believe that a definative answer would only come from primary sources such as unit diaries and original notations in the handwriting or personally signed by senior command such as Gen. Birdwood at Anzac Cove or in Cairo.
