{{RomanMilitary}}
The earliest Roman forts at Vindolanda were built of wood and turf.<ref name=":0">C.Michael Hogan. 2007. ''Vindolanda Roman Fort'', The Megalithic Portal, ed. A.Burnham [http://www.megalithic.co.uk/article.php?sid=17742]</ref> The remains are now buried as much as {{cvt|4|m|ft|order=flip}} deep in the anoxic waterlogged soil. There are five timber forts, built (and demolished) one after the other. The first, a small fort, was probably built by the 1st Cohort of Tungrians about 85 AD. By about 95 AD this was replaced by a larger wooden fort built by the 9th Cohort of [[Batavi (Germanic tribe)|Batavians]], a mixed infantry-cavalry unit of about 1,000 men. That fort was repaired in about 100 AD under the command of the Roman prefect Flavius Cerialis.<ref>Birley, Vindolanda Guide, 2012, pages 31–32.</ref> When the 9th Cohort of Batavians left in 105 AD, their fort was demolished. The 1st Cohort of Tungrians returned to Vindolanda, built a larger wooden fort and remained here until [[Hadrian's Wall]] was built around 122 AD, when they moved, most likely to Vercovicium ([[Housesteads Roman Fort#History|Housesteads Roman Fort]]) on the wall, about two miles to the north-east of Vindolanda.<ref name="Birley35">Birley, Vindolanda Guide, 2012, page 35.</ref>
