In 1844, Governor General Narciso Claveria led yet another expedition against Jolo and in 1848, Claveria with powerful gunboats Magallanes, El Cano, and Reina de Castilla brought from Europe supervised the attack on the Balangingi stronghold in Tungkil. The raid resulted in the capture of many Sama Balangingi and the exile of many to the tobacco fields of Cagayan Valley. The leader of the Sama, Paglima Taupan, was not captured. With the fall of the Balangingi, a powerful ally of the Sulu Sultanate was decimated, beginning the decline of the sultanate's maritime sea power. In 1850, Governor General Juan Urbiztondo continued with Claveria's campaign and annihilated the remaining Balangingi strongholds at Tungkil. A raid on Jolo that year was a failure. On 28 February 1851, Urbiztondo launched another campaign against Jolo, razed the whole town and confiscated 112 pieces of artillery. The Spanish troops later withdrew. Also, in 1851, a peace treaty was signed between the Sulu Sultanate and the Spanish, though the terms were understood differently by each party.
