Whakaotihia te rerenga e whai ake nei: I tae atu te ope a Scott ki te Raorao o Mexico i te marama o Akuhata 1847, i taua wa kua whakauruhia e Santa Anna tetahi ope tata ki te 25,000 nga tangata. Na te mea kaore he pakitara o Mexico City, kaore hoki e taea te tiaki, i whai a Santa Anna ki te wikitoria i a Scott i roto i te pakanga, i kowhiri ki te whakaeke i tetahi paruru tata ki te Awa o Churubusco, e hia maero ki te tonga o te taone nui. I tiimata te Pakanga o Contreras i te ahiahi o Akuhata 19, i te wa i whakaekea ai e te ope taua o Mexico i raro i te rangatira a Gabriel Valencia, ka peia e ia tetahi roopu Amerika i whakawakia ki te hanga huarahi. I te ata tonu o te ra i muri mai, ka ohorere te ope a Amerika i arahina e te Tiamana Persifor Frazer Smith, ka whakangaromia te ope a Valencia. Ko nga korero mo te hinganga i Contreras i whakawehi i te toenga o te ope a Santa Anna, a ka akiaki tonu a Scott i te whakaeke, ka tiimata te
Te Pakanga o Churubusco. Ahakoa te kaha o te paruru i whakaarahia e te Battalion o Saint Patrick me etahi atu waahanga, ka tere te kaha o Scott ki te patu i te ope Mexico kua ngoikore. Whai muri i te pakanga, i whiriwhiria e Santa Anna he rangimarie me Scott, a, i whakamohio te minita mo nga iwi ke o Mexico ki a Trist kua rite ratou ki te tiimata i nga whiriwhiringa hei whakamutu i te pakanga.
