Marshal Soult began a counter-offensive (the Battle of the Pyrenees) and defeated the Allies at the Battle of Maya and the Battle of Roncesvalles (25 July). Pushing on into Spain, by 27 July the Roncesvalles wing of Soult's army was within ten miles of Pamplona but found its way blocked by a substantial allied force posted on a high ridge in between the villages of Sorauren and Zabaldica, lost momentum, and was repulsed by the Allies at the Battle of Sorauren (28 and 30 July) Soult ordered General of Division Jean-Baptiste Drouet, Comte d'Erlon commanding one corps of 21,000 men to attack and secure the Maya Pass. General of Division Honoré Reille was ordered by Soult to attack and seize the Roncesvalles Pass with his corps and the corps of General of Division Bertrand Clausel of 40,000 men. Reille's right wing suffered further losses at Yanzi (1 August); and the Echallar and Ivantelly (2 August) during its retreat into France. Total losses during this counter-offensive being about 7,000 for the Allies and 10,000 for the French.
