In the Senate resolution, the Senate said the Tausug warriors and members of their families who fought the foreign invaders in the "Battle of Bud Dajo" deserve to be recognized for their courage and heroism.

"Seldom in history do we find such bravery as that displayed by the Tausugs at Bud Dajo," said Senate Minority Leader Aquilino "Nene" Q. Pimentel Jr. (PDP-Laban), principal author of the resolution.

The senators proposed that March 6, 2006 and every year thereafter be declared as "Bud Dajo Day" in remembrance of the supreme sacrifice of the defenders of the Bud Dajo for love of their homeland.

Co-authors of the resolution were Senate President Franklin Drilon and Senators Juan Flavier, Francis Pangilinan, Edgardo Angara, Rodolfo Biazon, Pia Cayetano, Loi Ejercito-Estrada, Jinggoy Estrada, Richard Gordon, Panfilo Lacson, Alfredo Lim, Jamby Madrigal, Sergio Osmeña III, Ralph Recto, and Ramon Revilla, Jr.

The Battle of Bud Dajo happened on March 5-7, 1906 after the Moros of Sulu refused to recognize American sovereignty over their islands and pay taxes or surrender their weapons to the colonial authorities.

When the United States deployed about 800 troops to subjugate the Moros of Sulu, the inhabitants hardened their resistance and retreated to the top of Bud Dajo, the lava cone of an extinct volcano, and fortified it.

Bud Dajo, about 10 kilometers from Jolo, has an altitude of 2,100 feet. During the ensuing battle, the American soldiers, equipped with rifles, grenades, and cannons, stormed Bud Dajo, killing almost all of the 1,000 Moros who were armed only with kris, spears and, a few rifles.

The colonial troops suffered minimal losses — 21 killed and 75 wounded.

The American assault, composed of infantry, cavalry, and artillery men, was supported by two-quick firing guns from the gunboat Pampanga that was moored at the Sulu Sea.
