Final answer:
The experienced Yorkist general who directed the archers at the Battle of Towton during the Wars of the Roses is likely to be Lord Fauconberg. However, the reference provided refers to General William Howe, a figure from the American Revolutionary War, not the Wars of the Roses.
Step-by-step explanation:
Unfortunately, the reference given doesn't relate to the Yorkist general involved in the Battle of Towton during the Wars of the Roses. The figure presented, General William Howe, conjured up from a 1777 portrait, is linked to the American Revolutionary War and not the Wars of the Roses. The key figure you might be referring to in the context of Towton would be Lord Fauconberg, who played a pivotal role in orchestrating the Yorkist archers' strategies, contributing significantly to the Yorkist victory at Towton.
