3.11 Cannon balls in cases

Cast-iron cannon balls have been found in great numbers. Approximately amidships these cannon balls are cemented to the top of the iron bars. Originally, they were packed in wooden boxes of sizes varying from 62 x 45 to 80 x 53 cm and a height of 30 to 40 cm. The wood has decayed, but the iron shot has concreted in a box-shape. Two rows of four to five boxes are discernible (fig. 41), but the distribution of stray cannon balls suggests that the whole area between 11.50 and 16.75 (3.5 x 6.75 m) was packed with 40 boxes at least. Depending on calibre, each box would weigh 400 kg or more, a shipment of at least 16 ton.

Only seventeen of these cannon balls have been recovered from the wreck. The calibres vary from 37.9 to 96.0 mm. The sample is interpreted as including four one-pounders, five two-pounders, one three-pounder, one four-pounder, four five-pounders and one seven-pounder (van der Linden forthcoming). This shot is assumed to be cargo; the calibre is too small for the cannon discovered at the wreck site.
