219 cohors XX Palmyrenorum
Among their many military innovations, the Romans seem to have invented paperwork, a matter about which we’ve commented before. Some of this paperwork actually survives, usually in trash heaps near long-abandoned fortresses.
One of the greatest troves of surviving Roman military documents comes from the ruins of the fortress-city of Dura-Europos, about ten miles north of where the Euphrates River passes out of modern Syria into Iraq, a site now devastated by the maniacal minions of the self-proclaimed “Islamic State.” Most of these documents are from the cohors XX Palmyrenorum equitata milliaria, a combined infantrycavalry regiment. The cohort formed the principal garrison at Dura-Europos from as early as AD 170 until the city was taken and destroyed by the Persians in 257. The XX Palmyrenorum included six centuries (companies) of infantry and five turmae (troops) of cavalry plus a troop of dromedarii or “camelry,” with a normal complement of some 1,100 to 1,200 men, rather more than the thousand implied by the tag “milliaria.” The surviving paperwork is extensive, hundreds of documents having been found, some fragmentary and some largely intact. Several documents are so detailed we know the names of nearly a thousand of the troops, and even those of some of the horses.
Among the papers that come down to us are portions of several morning reports, which can be pieced together to give us an idea of the daily routine and duties of an elite unit on frontier duty in the early Third Century.
A morning report from an uncertain date in the latter half of AD 219 details the “ordinary” distribution of the troops in the cohort.
Cohort Strength 1,210 men
Present at Dura ( 936)
Headquarters [ 30]
Guards [ 21] a
Other [ 885]
Detached Service ( 274)
Headquarters [ 30]
Imperial Delegation [ 56] b
legio IV Scythica [ 1] c
Scouts [ 14]
Lion Hunting [ 7] d
Outposted [ 196] e
Notes:
a. Guarding the unit standards, shrine, and bank, rather than on ordinary sentry duty.
b. Men detailed to express the loyalty of the cohort to the Emperor Elagabalus (proclaimed June 8, 218), in far-off Bithynia (northwestern Turkey-in-Asia), close to 1,500 miles away by the fastest route.
c. Apparently, a liaison to the detachment of the legio IV Scythica that was also based at Dura.
d. Procuring lions for the garrison’s arena.
e. Stationed along the Euphrates in over a dozen posts. There were 91 men at Becchufrayn and 63 more at Appadana to conduct patrols along the frontier with Parthia and from 1-10 men at the smaller posts, combining the duties of customs agents, border guards, and local police.
These figures seem to have been more or less stable over many years. A report for March 27, AD 233, indicates cohort strength at 1,137, which probably does not include its commander, the tribune Iulius Rufianus, otherwise unknown to history, nor his personal staff and bodyguards. An actual nominal roll of AD 239 dated May 31-June 1 shows 914 infantry, 223 cavalry, and 34 camelry, for a total of 1,171, again without the commander or his entourage.
The AD 233 report also details personnel distribution in the cohort.
Milites caligati (literally “booted soldiers,” i.e. infantry), 880, including officers. There were nine centurions: one the primpilus or chief centurion of the cohort, one as chief of infantry, one as chief of cavalry, and one for each of the six foot centuries.
There were also eight duplicarii (double-pay men, more or less
“sergeants”), and one sesquiplicarius (pay-and-a-half man, “corporal”);
Milites equitata (“horsed soldiers”), 223, including 5 decuriones (platoon leaders), 7 duplicarii, and 4 sesquiplicarii;
Dromedarii (camelry), 33 and 1 sesquiplicarius. Normally this would have been commanded by a decurio, so perhaps the post was vacant and command had devolved on the sesquiplicarius.
In this morning report Tribune Rufianus issues the standing orders for the day and gives the watchword, “Holy Mercury.” He then details personnel transfers or movements by name, designates the commander of the watch and the personnel assigned to guard the regimental shrine, and gives instructions on preparations for religious observances to be held on the 29th.
This was a standard format, repeated in the morning reports over the next few days, with some variation, such as the notice of the death of one man, the detailing of several men for special duties, such as collecting wood for the unit baths, a couple of discharges, several men listed as AWOL, and similar routine information.
Not very much different from a modern morning report.
