A note on place-names
Because various streets and buildings have been renamed since 1914, the first reference to each gives both titles, for example ‘Royal Barracks (now Collins Barracks)’; ‘Sackville Street (now O’Connell Street)’. Subsequent references use whichever name is most appropriate in the text.
A note on money
The pound (£) was divided into twenty shillings (s) and the shilling into twelve pence (d). Intermediate amounts were written in a combination of denominations, e.g. 3s 6d; £2 3s. Some relatively small amounts in pounds might be written entirely in shillings, e.g. 42s (£2 2s).
