You quoted Lincoln's inauguration speech: "...but beyond what may be necessary for these objects (collect tariffs), there will be no invasion,..."

That was on March 4, 1861.

Four days later, the US Congress adjourned.

The next day, Mr. Lincoln invited the Cabinet to begin planning the invasion of Ft. Sumter and Pensacola.

Mr. Lincoln's statesman like efforts for peace lasted for 5 days.

The next day, Mr. Lincoln invited the Cabinet to begin planning the invasion of Ft. Sumter and Pensacola.

How do you invade your own forts located in your own cities?
