Almost six months have passed since the start of the war, and the Japanese behemoth had proved to be almost unstoppable across the Pacific. Last week, we saw them complete their invasion of Burma, another victory in a long string of triumphs; yet we also saw there a huge participation by one of the most forgotten allies of World War Two: Nationalist China. Today, we are going to see war resume in the Chinese mainland as the Japanese prepare for a new offensive in retaliation for their participation in the Doolittle Raid.
