Dardanelles: Book 3 in the Changed Course series

By Tony Dunning

The Dardanelles should have been impossible.

In 1909, one decision changed history.

When the British War Office approved Commander Godfrey Herbert's revolutionary manned underwater craft instead of rejecting it, the course of the First World War began to diverge from the history we know.

Now, in the summer of 1915, that decision is reshaping an entire campaign.

As the Gallipoli offensive unfolds, Herbert's daring operators slip beneath the waters of the Dardanelles, cutting defensive nets, clearing deadly minefields and striking where no conventional fleet can reach. Battleships that were lost in our history survive to bombard Ottoman positions, giving Allied troops a fighting chance to establish themselves on the peninsula.

Yet victory is far from certain.

The mountains above ANZAC Cove remain unforgiving. Mustafa Kemal adapts with brilliant determination, turning Gallipoli into a brutal war of trenches and attrition. German submarines arrive to hunt Britain's mysterious underwater force, while Berlin races to understand the secret weapon that is changing naval warfare.

As British battleships finally force their way into the Sea of Marmara, the strategic balance of the war shifts. Constantinople trembles. Russia's lifeline begins to reopen. Bulgaria hesitates. Across Europe, governments realise that no harbour, no fleet and no coastal fortress can ever again be considered safe.

The Herbert Programme has proved that history can be rewritten beneath the waves. Now the enemy intends to do the same.

Dardanelles is the thrilling third novel in the Changed Course series, an epic alternate history saga that asks a single question:

What if Britain had said "yes" in 1909 instead of "no"?

Perfect for readers of Harry Turtledove, Robert Conroy, and Douglas Reeman, and for gripping World War I military fiction, this action-packed novel combines real historical events with a compelling alternate timeline where innovation changes the fate of nations-and the future of war itself.
