The Great Siege Ledger: Reconciling Casualty Figures
In a sixth-form seminar on the 1565 Siege of Malta you are given three extracts and asked to write a source criticism under timed conditions. Extract A is a chronicle published in 1567 by a knight of the Order, dedicated to the Grand Master; it claims that 25,000 Ottoman soldiers died and only 8,000 Christians. Extract B is a letter written in July 1565 by a Venetian merchant in Messina, repeating news from a ship's captain; it says 'not above 9,000 Turks have died' and estimates 4,000 defenders. Extract C is a modern footnote summarising Ottoman payroll records: 22,000 effectives were paid in June 1565, but the registers do not record deaths. Your teacher asks you to judge which casualty figure is most defensible and to explain what the extracts can and cannot prove. You have 20 minutes and may not consult other sources.
1. Which figure for Ottoman deaths is most defensible, and which is least? Justify your ranking by reference to the function and timing of each extract.

None of the three extracts supplies a reliable death toll. Extract C is the most useful, but it gives 22,000 effectives paid in June, not deaths; using it as a casualty figure confuses the size of an army with mortality. Extract A is least defensible as a count: it was published two years after the siege by a knight of the Order and dedicated to the Grand Master, so its purpose was commemorative and patron-facing; inflating Ottoman losses magnified the Order's achievement. Extract B is earlier and less directly interested, but it is hearsay from a ship's captain and a merchant in Messina, so it cannot be treated as an eyewitness count. If forced to rank plausibility, the 9,000 figure is closer to a possible order of magnitude than 25,000, but the safest conclusion is that Ottoman deaths are unknown. A good answer distinguishes effectives, casualties and reports, and refuses to average incompatible figures.
2. How does the provenance of Extract A and Extract B shape what each can be used for?
Read the worked answer
Provenance determines use. Extract A's dedication to the Grand Master and its publication after the siege make it evidence for how the Order wanted the victory remembered: martyrdom, heroic defence, enormous enemy losses. It can be used for ideology and representation, not for precise numbers. Extract B's merchant letter shows what news was circulating in Messina in July 1565 and what a literate outsider found plausible; its value lies in reception and contemporary rumour, not in eyewitness accuracy. The two extracts can be cross-read: both agree the siege was bloody and that Christian numbers were lower, but their disagreement over scale reveals the gap between commemorative and commercial information networks. A candidate should not say one is simply 'biased' and discard it; each answers a different question.
3. What additional evidence would most improve your judgement, and what would it not settle?
Read the worked answer
Additional evidence that would improve judgement includes Ottoman muster rolls, galley provisioning accounts, burial registers, and letters from neutral observers such as Venetian or Genoese agents. Muster rolls could establish how many soldiers were present and whether reinforcements arrived; burial records might indicate minimum deaths. But these would not settle the question completely: armies often buried hastily, deserted, died of disease after the siege, or exaggerated losses for political reasons. The best answer therefore asks for evidence that can triangulate presence, attrition and reporting, while acknowledging that a precise casualty total may be unrecoverable. This is stronger than asking vaguely for 'more sources'.
