More often than not, Harbottle's spelling of names and places agrees with other sources. Therefore, the benefit of the doubt, when resolving discrepancies, has been ceded to Mr. Harbottle.
The usefulness of the Index, especially in the text-only version of this volume, is severely compromised. Where the Index disagrees with the text, it is assumed to have been an editorial error, and corrections have been made.
Where corrections disturb the alphabetic order, the items have not been repositioned, with a few exceptions noted below.
Several index entries ('Sandbag Battery', 'Stopford', 'Hans Waldmann'), violated the alphabetic order or were otherwise misplaced. They were retained as printed. Other entries were corrected (e.g. Olearchus/Clearchus, Oreizaga/Areizaga, Ouchterlony/Ochterlony) in such a way as to place them out of order. The original position is retained.
More strangely, on p. 287, there are entries for 'Ley' and 'Licias', both of which seem to be intended as references to 'Ney' and 'Nicias'. The entry for 'Licias' on p. 240 is duplicated later for 'Nicias' and was removed. The page reference (p. 68) for 'Ley' has been transferred to the list for Marshall Ney, and the entry for 'Ley' deleted as well.
No attempt was made to test each page reference for accuracy, but the entry for David II of Scotland was incorrectly given as page 274 (which does not exist). He is mentioned on p. [174] and the index was corrected. The last page reference for Prince Mentschikoff was also given as p. 274, and was removed.
The index item for 'Cacina' refers the reader to p. 47, where a mention of 'Cæcina' occurs. There is a separate item for 'Cæcina', referring to a different article on p. 68. The two items have been combined.
The index entry for 'Claulen' is doubly problematic. The name appears in the text as 'Clauleu'. The n/u misprint is a common one. In this case, however, there seem to be two. Neither the index or the text agrees with the historical 'marquis de Clanleu'. Both have been amended.
On p. 290, the entry for Muzuffa Jung refers to 'Muzuffer Jung' in the text. Other sources have 'Muzuffar' or 'Muzuffer' Jung, no doubt a transliteration issue. Following the text seemed the preferrable correction.
In the text, there are four references to a Samnite commander 'Pontius'. The index has two items 'Pontius, 62, 63' and 'Pontras, 53'. The name in the second item is an error. These refer to three battles: Caudine Forks B.C. 321 (p. 53), Ciuna B.C. 315 (p. 63), and Colline Gate B.C. 82 (p. 63). Gaius Pontius was the commander for the earlier battles, and the later battle involved a different commander, Pontius Telesinus. These errors were resolved by transferring the reference to p.63 to the earlier Pontius (and correcting his name). A fourth battle, also fought by Gaius Pontius at Lautulæ B.C. 316 (p. [136]) was missed.
