In page Benjamin Butler:

"

After Abraham Lincoln was elected president in November 1860, Butler traveled to Washington, D.C. When a secessionist South Carolina delegation arrived there he recommended to lameduck President James Buchanan that they be arrested and charged with treason. Buchanan refused the idea. Butler also met with Jefferson Davis and learned that he was not the Union man that Butler had previously thought he was. Butler then returned to Massachusetts,[1] where he warned Governor John A. Andrew that hostilities were likely and that the state militia should be readied. He took advantage of the mobilization to secure a contract with the state for his mill to supply heavy cloth to the militia. Military contracts would constitute a significant source of profits for Butler's mill throughout the war.[2]
