Any further development of Otho's policy was checked once Otho had read through Galba's private correspondence and realized the extent of the revolution in Germany, where several legions had declared for Vitellius, the commander of the legions on the lower Rhine River, and were already advancing upon Italy.
Setiap pengembangan lebih lanjut dari kebijakan Otho itu diperiksa setelah Otho telah membaca melalui korespondensi pribadi Galba dan menyadari sejauh mana revolusi di Jerman, di mana beberapa legiun telah menyatakan untuk Vitellius, komandan pasukan di bawah Sungai Rhine, dan sudah maju pada Italia.
