Tuhia he haere tonu mo tenei pene - Ko te mahi a Tremlett i muri mai ko te Peninsula Campaign. Mai i te Paenga-whāwhā ki te Hōngongoi, 1862, he wāhanga ia o tētahi ope nui e tata ana ki te 121,000 ngā hōia i whakarewahia e te Tumuaki George McClellan ki Fort Monroe i runga i te moutere o Virginia. Ko te mahere a McClellan ko te hopu i a Richmond kia mutu ai te pakanga, engari i whakakahoretia ia e General Robert E. Lee a i te mutunga ka peia te ope katoa a McClellan mai i te peninsula. I whawhai te ope a Tremlett ki Eltham's Landing, Seven Pines, Oak Grove, Mechanicsville, Gaines' Mill, Savage's Station
Ko Glendale, ko Malvern Hill.
