The number of beds occupied at any one time would depend upon the current military activity. The camp hospital within the besieged fort of Hod Hill (Dorset) in England, occupied from CE 44-51, might expect an occupancy of 12-20% of the force. At Inchtuthil on the River Tay in Scotland which was miles behind the lines, the maximum occupancy might be as low as 2.5%. On 18 May CE 90 (?) at Vindolanda, a fort near Hadrian's Wall in the far north of England, 4% of the 752 soldiers were indisposed - 15 were ill, 6 were injured, and 10 were suffering from eye problems.
