In February and March 1945, the US Third and Seventh Armies overran the southern portion of the German Rhineland in today's Rhineland-Palatinate and Saarland, advanced to the Rhine River, and crossed in multiple locations.

Part 1 - The Northern Palatinate - February and early March 1945 In process.

Although the Battle of the Bulge officially ended on 25 January, 1945, it was around 7 February before US lines were extended eastward to their position at the beginning of the battle.

Throughout February, the Third Army battled eastward over swollen rivers and through the Siegfrield line through the western Eifel.

Following will hopefully be a text/map duo for February 1945 for each Third Army corps, from north to south. VIII, XII, XX. (III Corps moved north from the Third Army to the Ninth Army on 10 February and thus doesn't figure in here.) Here is a synopsis:
Meanwhile, Patton's Third Army battered through the Siegfried Line in three areas:

Prum - Between 4 and 6 February, before the Rhineland Campaign formally began, Patton's VIII Corps breached the Siegfried Line northwest of Prum in the Schnee Eifel. Siegfried Line fortifications here were not fully manned. Prum fell on 12 February.
Bitburg - The Third Army's XII Corps made a costly river crossing near the junction of the Sauer and Our Rivers, cleared the Vianden Bulge and advanced to Bitburg, which fell on 28 February.
Trier fell on 2 March.

Beginning on 4 February, VIII Corps advanced eastward through the Siegfried Line, passing just to the south of the Schnee Eifel ridge. It captured Prüm on 12 February, and then assumed an aggressive defensive posture through the remainder of the month.

Arrows in the accompanying map are labeled with battalions and regiments of the 4th and 90th Infantry Divisions.

The XII Corps advance to Bitburg involved a costly wintertime crossing of the swollen Sauer River and then an advance through the Siegfried Line.

Southern Palatinate & Saarland, 11-24 Mar 1945

By 11 March 1945, almost all of the Rhine left bank was in Allied hands, except for the portion from Coblenz south into northeasterrn Alsace. Within two weeks this large salient was removed, primary by aggressive action by Patton's Third Army.

Treadway Bridge across the Moselle, March 1945

The US Third Army had cleared the Eifel in the northern Palatine north of the Moselle River in February and early March. The Seventh Army was charged with clearing the southern Palatinate. However, several issues impeded Seventh Army progress.

As late as mid-March, the Seventh Army had not regained all the northeastern France territory lost in the January German Nordwind counterroffensive. Thus it still had not advanced to the Siegfried Line.
The Siegfrield Line in the Seventh Army sector was a formidable barrier.
Seventh Army units had been involved in combat further south in the Colmar Pocket through the first week of February.

Considering these difficulties, the Seventh Army turned over additional portions of the Palatinate to the Third Army. The revised army boundary passed through Kaiserslautern as shown on the accompanying map.

Operation Undertone, the official Seventh Army offensive, began on 15 March and ended on 24 March.

In a remarkable but little-known offensive starting 11 March, Third Army units drove from the Moselle River south and east, occupying the bulk of the Palatinate. On 19 March, General Patton received permission for the Third Army to cross the Rhine. The stage for the second Rhine crossing was set.

On 23 March, Patton's 10th Armored Division, shown near Neustadt on the map, linked up with Seventh Army units advancing from the south, trapping the remaining Wehrmacht units.

The Palatinate Cleared - status on 21 March

As German resistance collapsed, Seventh Army units had access to a good highway from Zweibrucken northeast through the Kaiserslautern gap to the Rhine, from which they could stage for their pending Rhine crossing near Worms.

Missing from the above commentary is mention of the French First Army, also a part of the 6th Army Group. the Third Algerian Division is represented by the rightmost arrow on the bottom of the above map. Complemented by other French units, it advanced northwards on the Rhine plain.

On 27 March, the French sector was extended northwards to Speyer. There the first Rhine crossings by the French Army would occur.

A late March timeline:

21 Mar - Rhineland Campaign officially ends.
22 Mar - Central Europe Campaign officially begins.
22 Mar late - Third Army's first Rhine crossing, 5th Division at Oppenheim begins.
23 Mar - German withdrawal across Rhine in southern Palatinate begins.
23 Mar - Third and Seventh Army units meet near Landau in eastern Palatine, trapping remaining German Siegfried Line units.
23 Mar late - Operation Plunder, major Rhine crossing at Wesel, begins.
24 Mar - Operation Undertone, 7th Army offensive in southern Palatinate, ends.
25 Mar - Mopping up of rear guard and stragglers in southern Palatinate ends.
27 Mar - French sector is extended northward to Speyer.
