So only about 336 men were by the end of the campaign “missing”... from the British list. Discrepancies? Well. French claims to taking 600 prisoners can be attributed to their usual exaggeration OR due to them taking men recorded as wounded prisoner if they were left behind in which case your counting some them twice... Portuguese losses must also be factored in. But if Oman is double counting men who were wounded, then captured as two losses, or missing but rejoined their unit before the retreat was over as a loss, then we can assume losses are not as high as claimed in real terms.
2327 Casualties from 19 September to 19 November 1812.
348 Killed
1643 Wounded
336 Missing.
So I would estimate plausibly 1200 Portuguese casualties.
I’d need a lot more time to investigate losses from disease and sickness over the same period which are fairly constant through out the period.. but even if we double the losses... it lakes in comparison to allied losses in Market Garden.
