On December 10th, 11th, 12th, and 13th, Soult made a series of determined and often desperate attacks upon the British divisions, but without success, and was ultimately forced to fall back upon Bayonne, leaving the courses of the Nivelle, Nive, and Adour in the possession of the allies, who were thus enabled to obtain plentiful supplies for their needs, while the enemy were harassed by having their communications threatened and supplies restricted. During the conflicts between the 9th and 13th the French lost about 6,000 killed and wounded, and two guns. The British losses were 650 officers (including 6 Generals) and men killed; 233 officers, 215 sergeants, and 3,459 rank and file wounded; 17 officers, 14 sergeants, and 473 rank and file missing. The battle on December 13th, which determined the series of conflicts, was practically fought and won by the corps under Sir Rowland Hill--indeed the glory of the day was frankly given him by Wellington, who, taking him by the hand, said, "My dear Hill, the day is your own." There could be little doubt about that, for on the heights of St. Pierre--with only 16,000 men and 14 guns--he defied and drove off 35,000 French bayonets and 22 guns which assailed him in front, and the corps (8,000) of General Paris, with the Light Cavalry under Pierre Soult, which threatened his rear. The battle was regarded on both sides as "one of the most sanguinary that the French Army of Spain had fought, and that there was not one where so many deaths took place on the battlefield." No wonder the enemy never again took the offensive! The following regiments were present in the series of engagements: 1st, 2nd, and 3rd Foot Guards; 7th, 12th, 13th, 14th, 16th, and 18th Light Dragoons; 1st, 2nd, 3rd, 4th, 5th, 7th, 9th, 11th, 20th, 23rd, 27th, 28th, 31st, 32nd, 34th, 36th, 38th, 39th, 40th, 42nd, 43rd, 45th, 47th, 48th, 50th, 52nd, 53rd, 57th, 59th, 60th, 61st, 62nd, 66th, 71st, 74th, 76th, 79th, 83rd, 84th, 85th, 87th, 88th, 91st, 92nd, 94th, 95th, and the Rifle Brigade. Many of the regiments particularly distinguished themselves on the day of victory; notably the 92nd, which, scattering light troops that should have checked them, charged and repulsed a column; re-forming behind St. Pierre, they again advanced with colours flying and pibroch sounding, as if going to a review, and offered battle to a French column five times their superior: the challenge was, however, declined, for like Napier the French commanding officer recognised that men who could act so understood war.
