1 · Understand it

Why the Dardanelles

By early 1915 the Western Front was deadlocked and the easterners in the British Cabinet, Churchill among them, argued for an attack elsewhere. Turkey had entered the war in November 1914; forcing the Dardanelles would open a supply route to Russia through the Black Sea, might knock Turkey out, and might bring the neutral Balkan states in on the Allied side.

The strategic reasoning was sound. Russia needed munitions and had ports that froze; the Ottoman Empire was the weakest of the Central Powers; and a success would have relieved the Western Front's political pressure. The campaign is a case where a good idea was destroyed by execution rather than by conception, which is a distinction worth making because it is rarely true.

What went wrong

The naval attack came first. In March 1915 an Anglo-French fleet attempted to force the straits and lost three battleships to a minefield laid in a bay the sweepers had missed, with three more damaged. The attempt was abandoned, and the interval before the landings gave the Turks five weeks to fortify under the German general Liman von Sanders.

The landings on 25 April 1915 were at Helles and at what became Anzac Cove, where the Australian and New Zealand Army Corps came ashore about a mile north of the intended beach, under cliffs. The Turkish 19th Division under Mustafa Kemal held the high ground at Chunuk Bair, and Kemal's order to his men that he was not ordering them to attack but to die is the campaign's most famous phrase.

Deadlock followed within days and reproduced the Western Front on a smaller and hotter peninsula. The August offensive at Suvla Bay achieved surprise and was not exploited. Conditions were extreme: flies, dysentery, no shelter, water shipped in, and trenches yards apart. Around 480,000 Allied troops were committed and casualties were roughly 250,000, with Turkish losses of a similar order.

The evacuation, and the effects

The withdrawal in December 1915 and January 1916 was the campaign's one unqualified success. Deception was elaborate — self-firing rifles rigged with water tins, muffled boots, gradual thinning of the line — and around 105,000 men and most of the guns were removed without a single casualty on the final nights.

The effects were substantial and various. Churchill left the Admiralty and went to command a battalion in France. The Turkish victory gave Mustafa Kemal the reputation on which he founded the Turkish Republic. Russia remained cut off, which contributed to the supply crisis behind the revolutions of 1917. Bulgaria joined the Central Powers in September 1915, partly on the evidence of Allied failure.

And in Australia and New Zealand the campaign became a founding national story: Anzac Day is commemorated on 25 April, and the argument that colonial troops had been spent by British commanders became part of the case for independent foreign policy. That the myth is contested — the British and French lost more men there than the Anzacs — matters less than that it was believed and acted on.

The pairing in the essential question is the lesson. A faultless evacuation does not redeem the decision to land, and competence at one level cannot repair an error at another. That is the most transferable idea in the strand and it applies to Haig, to Jutland and beyond the option.

2 · Learn it — the notes

The dates that earn marks

March 1915
The naval attempt fails; three battleships lost to an unswept minefield. Why this date: The failure that gave the defenders five weeks and made surprise impossible.
25 April 1915
Landings at Helles and Anzac Cove; Kemal holds the high ground. Why this date: The date commemorated as Anzac Day, and the moment the campaign's outcome was effectively set.
August 1915
The Suvla Bay landing achieves surprise and is not exploited. Why this date: The last chance, lost to the same exploitation problem as the Western Front.
December 1915 – January 1916
Evacuation of around 105,000 men with almost no casualties. Why this date: The one success, and the pairing that makes the strand's argument.

The figures, and how far to trust them

  • About 480,000 — Allied troops committed to the campaign.
  • About 250,000 — Allied casualties, with Turkish losses of a similar order. (Casualty totals differ substantially between sources depending on whether sickness is included.)
  • About 105,000 — Men evacuated in December 1915 and January 1916, with almost no casualties.
  • 5 weeks — Between the failed naval attack and the landings — the warning given to the defenders.

The people to place

  • Winston Churchill — First Lord of the Admiralty; principal advocate of the naval attack and left office over its failure.
  • Mustafa Kemal — Commanded the 19th Division at Chunuk Bair; the reputation founded the Turkish Republic.
  • Ian Hamilton — Commanded the expedition; his headquarters remained offshore, which is part of the case against the command.
  • Liman von Sanders — German general who reorganised the Turkish defences in the five weeks the Allies supplied.

How historians disagree

Attributed interpretations, never voiced — the AO4 seam.

  • The 'sound idea, bad execution' reading: Forcing the Dardanelles was strategically intelligent and was ruined by delay, insufficient force, poor intelligence and command from a ship offshore. Contested by The reading that the operation was beyond what amphibious technique and communications could deliver in 1915, so that no execution would have succeeded and the concept was therefore the error..

What students say — and what is actually the case

Not this: Gallipoli was mainly an Australian and New Zealand campaign.

This: British and French forces committed and lost more men there than the Anzacs. The campaign's national significance in Australia and New Zealand is real and is a separate fact from the composition of the force.

Not this: The campaign failed because the Turks were unexpectedly strong.

This: The five-week warning after the naval attempt allowed Liman von Sanders to reorganise the defences. The Allies supplied the surprise they then lacked, which is a decision rather than an accident.

Two things students merge

Blurred: The naval attempt and the land campaign.

The distinction: March 1915 is a fleet action against minefields and forts; from April it is an amphibious landing and a land campaign. The first caused the second by removing surprise, and they should not be described as one operation.

Blurred: A successful operation and a successful campaign.

The distinction: The evacuation was a model operation inside a failed campaign. Judging the campaign by the evacuation is exactly the criterion error the strand exists to expose.

What a Grade 9 answer holds here

A Grade 9 answer separates the concept from the execution and then refuses to let the evacuation redeem either. A sound strategic idea, a naval attempt that removed surprise, five weeks handed to the defenders, and then a withdrawal conducted perfectly — the sequence shows that competence and correctness operate at different levels, and that the second cannot be inferred from the first.

3 · How it is examined

This strand is genuinely set through: Paper 2 Section A (a) (6 marks — “Describe TWO features of EITHER … OR ….”); Paper 2 Section A (b) (8 marks — “How far does Source A support the evidence of Source B about …? Explain your answer.”); Paper 2 Section A (c) (16 marks — “Extract C suggests that …. How far do you agree with this interpretation? Use Extract C, Sources A and B and your own knowledge to explain your answer.”).

What earns marks: The five-week interval, named as a cause. It converts 'the Turks defended well' into an explanation with a decision behind it, which is what the mark scheme means by analysis rather than description.

4 · Prove it — the questions

Answered inside Incandio, where a marker checks what a correct answer must contain and tells you which half was missing. The marking stays in the app; the questions are here.

  1. Describe TWO features of the Gallipoli campaign. [6 marks · Paper 2 Section A (a)]
  2. How far does Source A support the evidence of Source B about the Gallipoli campaign? Explain your answer. [8 marks · Paper 2 Section A (b)]
  3. Describe TWO features of the evacuation from Gallipoli. [6 marks · Paper 2 Section A (a)]
  4. Extract C suggests that Gallipoli failed because of poor leadership. How far do you agree with this interpretation? Use Extract C, Sources A and B and your own knowledge to explain your answer. [16 marks · Paper 2 Section A (c)]
  5. How far does Source A support the evidence of Source B about conditions at Gallipoli? Explain your answer. [8 marks · Paper 2 Section A (b)]

Think you understand it?

Reading is the start. On Incandio a topic counts as mastered only once you have taught it and defended it — the two things a revision guide cannot ask of you.

Incandio this topic → Prove it. Teach it. Defend it. What does “Incandio it” mean?

  1. Prove it — five questions on Gallipoli: reasons, features, evacuation and effects, marked on the spot, that tell you what was missing rather than just what was wrong.
  2. Teach it — Explain Gallipoli: reasons, features, evacuation and effects — what happened, why, and what it made possible — to Ember, an AI pupil who asks the awkward question. Understanding is credited; wording is not required.
  3. Defend it — Argue Gallipoli: reasons, features, evacuation and effects against Winston Churchill — three rounds, marked against descriptors you can read before you begin.
