he pakaru i waenga i te plenipotentiary o Ingarangi i taua whenua me te kawana o te kawanatanga o Canton e pa ana ki tetahi kaipuke iti, he lorcha ranei e kiia ana ko "Arrow", i hua ai te rangatira rangatira o Ingarangi ki te whakangaro i nga awa awa awa, ki te tahu 23 kaipuke no te Navy Hainamana me te pupuhi i te taone nui o Canton. I muri i te āta tirotiro i ngā tuhinga ā-ture, ka whakapono a Cobden he tino hē ēnei mahi. I kawea e ia he nekehanga ki te whare paremata mo tenei kaupapa, i arahi ki tetahi korerorero roa me te maumahara, neke atu i te wha nga po, i tautokohia e ia e Sidney Herbert, Sir James Graham, William Gladstone, Lord John Russell me Benjamin Disraeli, a ka mutu i te hinganga o Lord Palmerston ma te nuinga o te tekau ma ono.
