Were animals used to handle cargo aboard ships?

Were pack animals used to move cargo or ammunition at sea, or was the work mechanical and manual?

Manual handling appears to have done much of the work. Mule-powered port cranes and some attempts to use animals are recalled tentatively.

Manual labor appears to have accounted for much cargo and ammunition movement. Mule-powered cranes at ports are recalled as another possibility, although the recollection is uncertain. Some attempts to use animals are also suggested. No specific example establishes how extensively animals worked aboard ships at sea, so that part of the question remains open.
