Ala I Gallorum Sebosiana ( Cavalry Unit) – France

This cavalry regiment (ala) was formed in Gaul and named after its first commander Sebosiana. This cavalry unit of 500 men was in Carlisle in the year 105 (see https://www.jstor.org/stable/30030577) and a tombstone was found at Inveresk in Musselburgh around 140 AD (see https://archaeology.co.uk/articles/bodyguards-corpses-and-cults.htm and https://canmore.org.uk/site/295681/carberry). They trained with lances, bows, slings and javelins. It was at Lancaster probably after 125 AD, with a standard compliment. An inscription shows that this regiment was back for a period in the middle third century.
