Hi Mick!
I wonder if Mack has access to the Police Gazette for those years - maybe you could ask him if he doesn't pick up this thread!
Army: Deserters
There is an incomplete card index at The National Archives to army deserters (1689-1830), compiled from bounty certificates of rewards paid out of locally-collected taxes to those who had turned the deserter in. The index covers only rewards paid out in London and Middlesex (from E 182/594 to E 182/673 ) and in Bedfordshire, Berkshire, Buckinghamshire, Cambridgeshire and Cheshire (E 182/2 to E 182/114 ). The main part of the index is of deserters, giving date and regiment:, as well as a reference to E 182 by piece number and sub-number. There is also a sequence by county, as well as cross-references from entries like "Dragoons", "Fencibles" and "Militia" to the main sequence. If you order one of these E 182 references, you will get one or more large boxes of tax documents, with no obvious clue as to where the bounty certificates will be. Look amongst the many unwrapped bundles of documents for a bundle wrapped up in linsen paper (a stiff brown paper).
There are registers of deserters, 1811-1852, in WO 25/2906 to WO 25/2934 . Until 1827 they are kept in three series, for cavalry, infantry and militia (the latter up to 1820 only). After 1827 they are arranged by regiment. These registers give descriptions, dates and place of enlistment and desertion, and outcome. There are registers of captured deserters, 1813-1845, in WO 25/2935 to WO 25/2951 , with indexes up to 1833 in WO 25/2952 , WO 25/2953 , and WO 25/2954 . Deserters who surrendered themselves under proclamation, 1803-1815, are in WO 25/2955 . On capture, some deserters were sentenced to imprisonment on the Savoy hulk: there are unindexed registers for the hulk, 1799-1823 (WO 25/2956 ).
Local newspapers and (for 1828 to 1845) the police newspapers Hue and Cry and the Police Gazette carried details of deserters, giving name, parish and county of birth, regiment, date and place of desertion, a physical description and other relevant information. For deserters in Australia (HO 75 ), consult Y Fitzmaurice, Army Deserters from HM Service (Forest Hill, Victoria, 1988)
