From October 1810 Marshal Masséna's Army of Portugal had been tied down in an increasingly hopeless stand-off against Wellington's Allied forces, safely entrenched in and behind the Lines of Torres Vedras. Acting on Napoleon's orders, in early 1811 Marshal Soult led a French expedition from Andalusia into Extremadura in a bid to draw Allied forces away from the Lines and ease Masséna's plight. Napoleon's information was outdated and Soult's intervention came too late; starving and understrength, Masséna's army was already withdrawing to Spain.
