Answer:
The Dardanelles campaign was a failure for Great Britain.
Step-by-step explanation:
In the first place the Dardanelles campaign was a failure for Great Britain. Because, it was a very important strategic point due to its geographical location and the utility it provided to the power who dominated it. In second place because it was a big impact into Great Britain's and French's alliance reputation. But in third place because major personalities like Winston Churchill himself were in command of that fight and they weren't able to achieve success in it. But in fourth place because it made a perfect combination of failure with the Gallipoli defeat and dragged too much attention to the strength of the alliance.
