 Here is a link to some numbers from the official reports on the battle. A couple of points. It is interesting to note that these figures are described as the British and Hanoverian Army (not armies). Also something worth footnoting in the article battle box next to the Allied missing "The greater number of the [British and Hanoverian] men returned missing had gone to the rear with wounded officers and soldiers, and joined afterwards. The officers are supposed killed".
