The ad starts with all the men whistling the song which they sung as they made the charge, and shows them bowing their heads and stopping whistling one by one to represent the fallen.

When all these young, fit, healthy men stand in front of the Shrine of Remembrance at sunset, you really have a sense of the scale of loss sustained on the battlefield 100 years ago.

The 16th Battalion suffered heavy losses during a hellish fire fight at Bloody Angle on the hills at Gallipoli. First-hand accounts talked about the men singing as they went into battle despite the treacherous conditions. Of the 600 in the Battalion, 338 young men were killed during the charge at Bloody Angle. The Raise a Glass campaign has a cast of 338 men - one representing each of those fallen men.
