[3] "Heneral Tibo", as he was often referred to, is credited for having established units of the Katipunan in the towns of Polo, Obando, Marilao, Meycauayan, Bocaue, Santa Maria, and San Jose del Monte in Bulacan, and of Caloocan, Malabon, Navotas in Bataan.
In August 1896, when Spanish authorities discovered the existence of the Katipunan and moved against it, Bonifacio was away, conferring with de León at Pasong Balite on the outskirts of Bulacan.
[2] When Aguinaldo later asked him to commit his forces to the First Philippine Republic, de León was reluctant to do so, being loyal to Bonifacio.
[1] On February 18, 1968, the Sangguniang Nayon (Village Council) of Torres Bugallon signed into law the renaming of their community after Hen.
A stone monument was raised by his comrades (Veteranos de la Revolución) in memory of Heneral Tibo in the town of Timog, Bulacan.
