Roman lead sling bullets (glandes) have been found at Windridge Farm near St Albans in Hertfordshire since the 1970s. A previous study suggested these missiles could have originated from a plough-disturbed hoard of Roman lead objects. More recent discoveries of glandes from other sites throughout Europe have enhanced our understanding of depositional characteristics, morphology and lead sources for Roman sling bullets and this paper offers an alternative explanation for their loss. Their atypical form (for Britain), and the prospect of a continental origin of the lead ore for their manufacture, suggest an early date of deposition. We also argue that the number of bullets and the pattern of their dispersal are indicative of an episode of conflict. After review of attested early military engagements that could have taken place in the vicinity, we propose that the projectiles may relate to one of two events: Claudius's invasion under the auspices of Aulus Plautius in a.d. 43 or Caesar's second incursion of 54 b.c.

Excavations in Insulae II, III and XIII in the southern half of Verulamium demonstrated the absence of occupation prior to the late first century and the relatively late development of the street grid in this area. This forced a re-evaluation of the date of the 1955 ditch, suggesting it was not dug until the Flavian period. The excavations also demonstrated that Watling Street had never bisected Insula XIII on the south-eastern side of the Forum-Basilica, thus negating a major argument for the presence of a Claudian fort under the centre of the later town. A restricted excavation in the northern corner of Insula XIII revealed evidence for the location of the town’s baths, while excavation in Insula XIII revealed a long sequence of industrial and domestic occupation stretching from the late first to early fifth centuries. Evidence for continued occupation into the fifth century or beyond was recovered from Insula II, and to a lesser extent, in Insula XIII.
