Example Input: Question: In what year was the commander in chief who sent Elles to investigate the first tanks born?

In January 1916, as a General Staff Officer (GSO), Elles was sent by General Sir Douglas Haig, the Commander-in-Chief (C-in-C) of the BEF on the Western Front, to investigate the first tanks or "caterpillars" being built in England.

His responsibilities included its advanced training and tactical employment. He also commanded the large central depot and workshops established near Bermicourt.
