Historical stories
Cao Ba Quat (1808 - 1855) was a teacher at Quoc Oai district. He saw the unique beauty of Hoang Xa land, so he wrote 4 poems on Sai Son mountain cliffs and today he still leaves his handwriting in the cave. Witnessing the country's misery under the rule of the Nguyen Dynasty, in December 1854, he commanded the uprising army to rise up against the Nguyen Dynasty government in My Luong, Son Tay province (today My Luong commune, Chuong My district, Hanoi). Cao Ba Quat's army fought a fierce battle with the Nguyen Dynasty's army led by Son Tay commander Le Thuan at the foot of Hoang Xa mountain. In this battle, Cao Ba Quat died in battle.
In the Hoang Xa cave, there are many steles carved on the cave walls. In particular, at the center of Hoang Xa cave, there is a statue of Dong Cac Dai Hoc Si Cao Xuan Duc (1843 - 1923). Cao Xuan Duc was an upright and patriotic mandarin. He held many different positions such as Kinh Lich, Tri Huyen, An Sat, Tong Doc, Tong Tai, Thuong Thu, Dong Cac Dai Hoc Si... Due to disagreements with Truong Nhu Cuong, he did not sign the petition to the king, and was later demoted to Tri Phu Quoc Oai. Moved by the spirit of Dai Hoc Si Cao Xuan Duc, after his death, the people of Quoc Oai carved a statue of him in the middle of the cave to worship him.
Hoang Xa revolutionary base
After the collapse of the feudal regime, the Democratic Republic of Vietnam was born, however, at the end of September 1945, France returned to invade our country. Under the leadership of the Party, the entire army and people continued to unite to expel the colonialists. In the Hoang Xa mountain area, many important events took place associated with our people's resistance war against the French. Before retreating to Viet Bac, on the night of March 2nd to the morning of March 3rd, 1947, President Ho Chi Minh chaired a meeting of the Government Council and rested at Hoang Xa cave. During the resistance war against French colonialism, Hoang Xa cave was also the residence of the Inter-zone 2 Resistance Committee.
On April 12, 1949, the French colonialists used 2,000 soldiers, including armored vehicles, artillery, and additional aircraft support, to sweep the Hoang Xa mountain and cave area. Faced with the enemy's continuous and fierce attacks, the 385th Company coordinated with the local army, people, and guerrillas to organize a coordinated counter-sweep. In this battle, many French invaders were killed and captured, which contributed to promoting the fighting movement and raising the patriotism of our army and people in the long resistance war against the French colonialists. In the fight to protect the homeland, many beloved children of the Vietnamese motherland were sacrificed. To commemorate this sorrowful day, every 15th day of the 3rd lunar month, the local people organized a memorial day. Later, the Quoc Oai District Martyrs Cemetery was also built in front of Hoang Xa Cave.
