Later, in the South, he rendered brilliant service which made possible the final American victory at Yorktown.
Henry Knox, a Boston bookseller, had, like Greene, only slight training for military command.

It shows the dearth of officers to fight the highly disciplined British army that Knox, at the age of twenty-five, and fresh from commercial life, was placed in charge of the meager artillery which Washington had before Boston.

It was Knox, who, with heart-breaking labor, took to the American front the guns captured at Ticonderoga.

Throughout the war he did excellent service with the artillery, and Washington placed a high value upon his services.

He valued too those of Daniel Morgan, an old fighter in the Indian wars, who left his farm in Virginia when war broke out, and marched his company of riflemen to join the army before Boston.
