On April 25th each year, Australia and New Zealand celebrate ANZAC Day. It was originally established to commemorate their troops who landed at Gallipolli in the Mediterranean on that date in 1915.
A great many of them died there, partly due to inept Allied planning and mishandling of the campaign, partly due to a vigorous Turkish defense, partly to endemic diseases. Their experiences gave rise to what became known as the 'ANZAC spirit':
The Anzac spirit or Anzac legend is a concept which suggests that Australian and New Zealand soldiers possess shared characteristics, specifically the qualities those soldiers are believed to have shown on the battlefield in World War I. These qualities cluster around several ideas, including endurance, courage, ingenuity, good humour, larrikinism, and mateship. According to this concept, the soldiers are perceived to have been innocent and fit, stoical and laconic, irreverent in the face of authority, naturally egalitarian and disdainful of British class differences.
The Anzac spirit also tends to capture the idea of an Australian and New Zealand "national character", with the Gallipoli Campaign often described as being the moment of birth of the nationhood of both Australia and New Zealand.

ANZAC Day has since come to serve a wider purpose, commemorating all those Australian and New Zealand service personnel who've died in conflicts since World War I as well. Dawn services are held in many centers in both nations on April 25th each year. Here are two pictures of this year's services. (Remember that Australia and New Zealand are across the International Date Line from us, so as I write these words in the USA, at about 11.30 p.m. Central time on April 24th, it's already 2.30 p.m. on April 25th in Sydney, Australia).
It's impressive to see tens of thousands of people getting out of bed before dawn to honor their country's servicemen on ANZAC Day. May we follow their example here in the USA.
May the souls of all departed ANZAC's, through the mercy of God, rest in peace.
