Bulwarte, a historic landmark, still stands as a mute testimony to the courage of the early inhabitants of Aloguinsan. Because of the frequent Moro attacks, the natives, under the supervision of the Spaniards, constructed a watchtower on top of a hill at the mouth of a river. From this vantage point, they could see incoming Moro vintas.
One night (a full moon and favorable winds), the Muslim invaders approached the village. With old people, women, and children safe behind the hills, the men began firing their cannons and did not stop until the pirates were annihilated. It was the end of Moro assaults.
The historic hill of Villona between the barrios of Olango and Cawasan was also the site of a battle between the American forces and Filipino revolutionist. The rebels under the leadership of Anastacio de la Cruz encountered the forces of Lt. Walker on Holy Thursday on April 1903. Lt. Walker and a number of his men were killed. The following day, Good Friday, Lt. McCoy took over the command of the American troops and outfought the Pulahanes (the rebels because of their red headbands were known as such.) who were defeated.
The courage and patriotism of the Aloguinsan were again tested in World War II. Cebuano guerillas from the place stubbornly and fiercely resisting Japanese invaders in barrio Konguigon resulted in the death of many Japanese soldiers. The enemy retaliated by killing many civilians, including babies, and there entered by joint Filipino and American troops together with the Cebuano guerillas until the end in the Second World War.
