was his highest rank. He was murdered in 1848 when he was Minister of War in Austria (you're off by 1 year with 1949).

sorry 1849

He had the rank of General

You should refer to him either as General of as Minister -- he was Minister of War when he was killed.

As a result of this assault the Minister Theodor Baillet von Latour was killed.

I know you want a translation into English, well, here's the correct German term, maybe others can help, I'm looking myself and should soon find something useful.

"Eine harmlose Exhorte an die Plenarversammlung des Katholiken-Vereins am 1. August, ebd. 93-96; Politische Passionspredigten nebst der Rede zum Seelenamte weil. k.k. Feldzeugmeisters Grafen Baillet de Latour"

Perhaps his Majesty\'s remarkablest transaction, here on the Rhine, was this concerning Stanislaus. For Seckendorf the Feldzeugmeister was here also, on military function, not forgetful of the Diplomacies; who busily assailed his Majesty, on the Kaiser\'s part, in the same direction: \"Give up Stanislaus, your Majesty! (source: http://associate.com/gutenberg/etext00/History_of_Friedrich_...

First of all this was Latour's rank.

Secondly - this is the secondrank that comes after Filed Marshal which is the highest rank possible in Imperial army (corresponds to the Grand Admiral in Imperial Navy).

Fleet Admiral= High Admiral= Senior Admiral in Imperial Navy.

Colonel-General = corresponding rank in Imperial Army.

See table of military ranks at:

Basically, I agree with Klaus, and since I apparently happened to repeat his path of research, I am not going to quote the part stating Theodor Baillet de Latour held a rank of Feldzeugmeister.

The rank of a General in Austrria-Hungary was subdivided into that of Infantry, Cavalry, and Artillery (technical branches) (descending order of seniority):

*) Der "normale" General in der K.u.k. Armee wurde mit dem Zusatz der Waffengattung seiner ursprünglichen Ausbildung bezeichnet. Dies waren die Infanterie (GdI), die Kavallerie (GdK) und Artillerie bzw. techn. Waffengattungen (FZM = Feldzeugmeister).
http://land.heim.at/waldviertel/240124/1.Weltkrieg/Generale/...

The ranking was as follows:

*) Abbreviations for Commanders' ranks (in Austria-Hungary):
FM Feldmarschall
GO Generaloberst
GdI General der Infanterie
GdK General der Kavallerie
FZM **Feldzeugmeister**
FML Feldmarschalleutnant
Glt Generalleutnant
GM Generalmajor
Obst Oberst
Hpt Hauptmann

In English texts the rank does not normally get translated:

*) Advanced to the rank of **Feldzeugmeister** on the 27th November 1859 he was appointed Chief of the General Quartermaster Staff on the 31st of January 1860 followed by the Governorship of Hungary in April.
http://www.austro-hungarian-army.co.uk/biog/benedek.htm

**) promoted colonel in 1768
promoted general-major in 1789
Promoted feldmarschall-lieutenant, commander of the Order of Maria Theresa
Given command in Italy with rank of Feldzeugmeister in 1796.
http://www.historydata.com/biographies/beaulieu.html

The meaning is indeed “General of Artillery”:

*) Feldzeugmeister (FZM) (General of Artillery)
http://www.kitzbuhel.demon.co.uk/austamps/dixnut/dn2.htm

**) Besides the Kaiser, the most senior rank held by a serving officer prior to the outbreak of the war had been that of General der Infanterie/Kavallerie or **Feldzeugmeister** in the case of generals from the **artillery branch**.
http://www.austro-hungarian-army.co.uk/marshals.htm

As an optional (and imho a better, since it has a wider meaning than “artillery”) translation (which I would tend to trust since the author is apparently an educated native speaker) – “General of Ordnance”:

Alexander Archilovich was appointed head of the Pushkar. skii Prikaz or Artillery Department, and made **general of ordnance** (Feldzeugmeister) of the Russian army
(excerpt from "The Last years of the Georgian Monarchy, 1658-1832" by David Marshall Lang, University of London)
http://rustaveli.tripod.com/sakartvelo/history/17century.htm...

However, I would stick to the commonly used “Feldzeugmeister” (m.b. you would want to add an explanation as a footnote)

PS: I would recommend that you have a look at the following link: “THE AUSTRO-HUNGARIAN ARMY 1914-18” http://www.kitzbuhel.demon.co.uk/austamps/dixnut/dn2.htm. Piles of useful information you might find interesting!

The top rankings after a Field marshal are:
General
Lieutenant General
Major General
Brigadier ('Brigadier General' in US)
Colonel
Lieutenant Colonel
I believe Theodore Baillet was the equivalent of a general at the height of his career, but most of his army life he spent as a Lieutenant General and Major General
