旅はことゆえ無しに終わったと、古い日記に記されている。
The journey ended without incident, as recorded in an old diary.
The phrase is composed of ことゆえ (archaic reading of 事故, meaning 'incident' or 'mishap') and 無し (classical negative adjective meaning 'not exist'). The exact historical derivation is uncertain, but it follows a classical pattern of noun + 無し to mean 'without ~'.
