In an nutshell:

1)The outflanking of the Confederate positions' on the Rappahannock by the bulk of the Army of the Potomac crossing the Rapidan at Germanna Ford, followed by the crossing the Rappahannock of Union II Corps at Bank's Ford.

2) Deployment of the aforesaid bulk behind Lee's Army at Chancellorsville.

3) Crossing the Rappahannock by Union VI and I Corps south of Fredericksburg followed by a demonstrative attack on the Confederate right wing there.
