I have decided to model the Hessian contingent which went to Scotland for the "45". I know they did not take part in any real fighting, but I would quite like to re-create Murray's abortive siege of Blair Atholl Castle, and the Hessians were the possible relief force for that.
Stuart Reid's 1745 A Military History of the Last Jacobite Rising (page 106) says that the force comprised a battalion of Grenadiers, the Prince Maxmillian Regiment (2 Bns), the Ansbach Regiment (2 Bns) and 6 companies of Guards. However this book was originally published in 1996 and in his more recent Osprey Cumberland's Culloden Army (published 2012), Stuart Reid gives the organisation as six regiments, Garde, Prinz Maxmillian, Mansbach, Von Donop, Erbprinz and Grenadiere. These are all shown as of a similar size averaging 845 men each.
As I understand it, their organisation prior to 1760 was as single battalion regiments, each of 10 companies, as mentioned on page 19 of Stuart Reid's 2010 Osprey Frederick the Great's Allies 1756-63, so that is what I am going to go with.
There is a posting on this website from 2010, discussing Hessian organisation in the War of the Austrian Succession, which would clearly be the same as that for the Jacobite Rebellion (link below).

The consensus agreed this same organisation of single battalion regiments of 10 companies, but also mentioned one Grenadier company per regiment.
I understand that the Grenadiere Regiment started its life in 1697 as a composite battalion of 6 regimental grenadier companies, but was reconstituted as a permanent unit in 1702. In 1745 they were a similar size to other regiments, so they either had just 6 much larger companies, or they had reorganised themselves into 10 standard sized companies (I suspect the latter).
What I am not sure about is whether the regiments in 1745 had their grenadier companies with them (ie they actually comprised 11 companies). Since there was now a separate Grenadiere Regiment, there was no requirement to converge the other grenadier companies anymore, nor do the Orders of Battle for either the Jacobite Rebellion or the War of Austrian Succession show such a converged battalion. My conclusion is that the 1745 regiments did have integral grenadier companies, and that is how I am proposing to model them. I however doubt if the Grenadiere Regiment itself would have had an 11th company.
I have several books on the Jacobite Rebellion, including Christopher Duffy's "The 45", and I have recently ordered his The Best of Enemies – Germans versus Jacobites 1746, which should add to my knowledge.
Does anyone have any other information on this.
