They almost missed the brig. At the last minute they had to swim hard across the current to prevent being swept right past her. The combined flow of the great river and of the tide moved them much more quickly than they had appreciated. Jack and Dappa collided with the brig’s larboard anchor cable hard enough to leave long rope-burns on their bodies. The tun toddled downstream for a few yards and reached the end of its tethers just short of thudding into the brig’s stempost. Its momentum nearly yanked Jack and Dappa off the anchor cable, to which they were clinging like a pair of snails.
