He had, by most accounts, simply wandered off -- one historian suggests he had visited a brothel.

The Marco Polo Bridge incident is generally regarded as the start of the Second Sino-Japanese War, a conflict that would merge into the larger conflagration of World War II and cost millions of lives.
