For those whose ancestors served in World War I:
"The Austro-Hungarian Forces in the Field, October 1918." by UK War Office.
The entire 225 pages of the book is an Order of Battle for the Austrian Army
in 1918 -- tells what units made up various divisions and brigades (some
independent brigades) of the army at that time. There is an index of
regiments with their nationalities and Depot (HQ) cities given as well as a
list of new regiments numbered 104 and above -- with some information on the
older (lower numbers) regiments or recruiting districts from which their
troops came (i.e. 133rd Infantry: IV old II/101= the fourth batallion of the
133rd was formerly the 2nd batallion of the 101st regiment). Schutzen,
Honved (Hungarian), Landsturm, Feldjaeger, cavalry, artillery, dismounted
cav, technical troops, etc. are all detailed as single troop units and as a
part of a brigade or division.
Incidentally, IR 28, the Children of Prague, that deserted to the Russians is
in the Index with Czech/Polish as its nationality and Innsbruck (Bruck.)
listed as Depot for the I, II, and III Battalions. There is a footnote that
says the regiment was struck off the rolls of the Army for mutiny on May 31,
1915, but has now been reformed (Oct. 1918?). The old Ist Battalion is now
in the 94th--Reichenberg--regiment (may be the remnants of the old regiment
that did not desert).
IR 36 (Brunn) that also deserted in great part to the Russians was disbanded
on June 15, 1915 and was not yet reformed per October 1918. Thus if your
ancestor was in IR 36 he either was in the Czech Legion that fought in Russia
after May 15, 1915, or he was transferred to another Austrian regiment in
June, 1915. The War Archive could probably tell you which units received
soldiers from the old IR 35 in June, 1915.
The book also identifies a number of divisions and brigades, etc., that were
disbanded prior to October 1918 with the date when that occurred.
The book is an excellent source for those who are searching for a unit that
an ancestor was in during WW I. First of all it is in English!! Then, it
would take some study (plan to spend an hour or two) but one could look for
the name of the city that was known to be within an ancestral birth district
among all of the "Depot" cities named and thus identify the best
possibilities for units in which he may have served. Not an easy task but I
have not yet found any alternative that would make it easier. There is no
index of Depot towns in the book but there is an index of names of commanders
for those who have family lore or documents that mention a commander's name.
The book will also give alternative possibilities with lists of battalions
(from XXXX regiment) that made up mountain brigades or lists of newly formed
regiments with the numbers of the old regiments from which they got a
battalion or two.
Research on WW I soldiers is fairly difficult because Vienna does not have
all of the usual information that is available for soldiers pre-1868. It is
made doubly difficult because many men were recruited by a certain regiment
but ended up in special units that did not serve with the regiment -- and
whose records may not be with regimental records. There were also many
changes caused by attrition during the war -- if a company was reduced so
much that it was ineffective and reinforcements were not forthcoming its
surviving soldiers might have ended up as reinforcements for another company
from another regiment in the near vicinity. Thus a soldier did not always
serve in the same unit for the duration of the war.
This book provides the individual researcher with information to include in a
query to Vienna since it names the various troop units recruited in an
ancestral district in 1918.
It may be available via interlibrary loan or it may also still be available
for purchase direct from Battery Press (they are a mail order house), from
internet book dealers or from your local bookstore on special order.
