He sent a large French/Navarrese army commanded by General André de Foix, Lord of Lesparre, (or "Asparros" or "Esparre") across the Pyrenees, consisting of 12,000 infantry, 800 mounted knights, and 29 pieces of artillery. With the support of the population, in less than three weeks, all of Navarre was conquered. The only opposition came from Ignatius of Loyola's Castilian garrison of Pamplona. He in turn was severely wounded, trying in vain to defend the city castle. The army then moved into Castile, besieging Logroño.
