Denbu Island is one of Zhoushan Islands, with an area of about 15 square kilometers. The whole island is mountainous, with the mountains and artillery mountains as the highest, and only the beaches in the west and north are flat. There is a pier on Jiguan Reef on the north side of the mountain. Zhoushan Island is about 20 miles north of the island. On the west side of the island is the big ant island, and the sea surface of the two islands is about 2 miles wide; The sea surface between Taohua Island and Denbu Island is about 5 miles wide from north to south and 7 miles long from east to west.

At the end of August, the 2 1 Army 6 1 Division, known as the Red Army Division, received an order from the commander of the 7 th Corps, demanding that it be under the command of the 22 nd Army to undertake the task of liberating Zhoushan Islands, and left for the Zhoushan front in September of the same year.

101October 18, the assault troops of four battalions of the sixty-first division, taking advantage of the night and the fog at sea, broke through the waves and launched a fierce attack on the enemy on Taohua Island. After the troops landed, they rushed out and intervened boldly. By 4 am, 1300 people were on the defensive. Peach Blossom Island declared liberation.

After the liberation of Taohua Island, Denbu Island became the only remaining barrier south of Zhoushan Island. In order to strengthen Zhoushan's defense force, Chiang Kai-shek, Chen Cheng, Gui Yongqing and other Kuomintang ruling groups rushed to Zhoushan in mid-June, 5438+10 to plan defense measures, decided to set up the Zhoushan command post of the Southeast Military and Political Chief's Office to command Zhoushan's military and political affairs in a unified way, and urgently dispatched the 67th Army and the 19 Army of the 12th Corps to reinforce Zhoushan, making its defense force reach more than 90,000 people.

The defenders of Denbu Island are two regiments, 22 1 Division of the 87th Army. They built fortifications from the south edge to the depth, set up water flares, explosive barrels, bamboo walls, barbed wire, mines and other obstacles in an attempt to defend Denbu Island.

In order to seize the opportunity, conquer Denbu Island as soon as possible, and form the siege situation of Zhoushan Island Campaign, the commander of the Seventh Corps of our army sent a telegram to the 22nd Army, pointing out that Taohua Island Campaign was a model of grasping fighter planes, making bold assault, making a quick decision and winning victory, and ordered the 61st Division to quickly capture Denbu Island, creating favorable conditions for the general attack on Zhoushan Island.

6 1 division received orders to consolidate the occupied islands and capture the enemy islands, so it is difficult to form superior forces when attacking. In addition, more than 40 ships were damaged in the battle of Taohua Island, and enemy planes circled and bombed and strafed over Liuheng Island, Xiazhi Island, Taohua Island and the sea area day and night, constantly destroying our ships and cutting off our supply. Ships are bombed every day, and it takes time to repair them. In addition, the maritime transportation line is long, and the food and other materials needed by the troops are also in short supply.

Therefore, Hu Weiwei, the division commander of 6 1 Division, truthfully reported the actual situation to the 22nd Army and the 2nd1Army, and suggested to the 7th Corps Command that it was really difficult for the troops to attack Denbu Island quickly, and euphemistically suggested that the troops should take a break before attacking.

2 1 The army received a telegram and urgently dispatched a mountain artillery battalion of the Army Artillery Corps to cross the sea to the north and reach Peach Blossom Island. After receiving the telegram, the 22nd Army called life-saving equipment, demanding that 6 1 division launch an attack at the latest in early June 165438+, step by step.

At the end of 10, Xing Bangding, an operational staff officer of the 22nd Army, went to Taohua Island to check the preparations, and conveyed the 22nd Army's Operational Plan on Attacking Zhoushan Islands, demanding that 6 1 Division quickly capture Denbu Island before capturing Zhujiajian Island Island, and then cooperate with the 22nd Army to capture Zhoushan Island from the south.

Xing Bangding and Hu Wei are old friends. When Hu Wei was the director of the political department of the League branch, Xing was the head of the Guard Corps. When old acquaintances meet, they naturally say everything. He told Hu Wei quietly: the army chief of staff objected to your telegram asking to postpone the attack.

According to this situation, the leaders of the 6 1 division conducted research and decided to launch an attack at 5438+0 1 in early June according to the instructions of the superior. After the decision, Mr. Hu made the following arrangements for attacking Denbu Island according to the Operational Plan: the 182nd Regiment, the 183rd Regiment and the 1st Battalion were the first echelon; 183 Regiment 3 Battalion 2 Battalion 1 Company is the reserve team, responsible for attacking the island and destroying the enemy. The newly transferred artillery regiment 12 mountain artillery was deployed in Jiucai Mountain and Maoshan Mountain on the north side of Taohua Island for support; 18 1 group stays in Taohua Island, controls other occupied islands, prevents the enemy from landing, and prepares to take the main task when seizing Zhujiajian Island Island. Three battalions deployed by the frontline troops need to land between Wangjiaao and Xi 'ao. After landing, the 182 regiment, except for a company that developed to Huoshaowan Mountain in the northeast of the island, quickly captured Paoshan Mountain and ZhangWang Wan Mountain, then attacked Jiguan Reef, occupied the dock, cut off the enemy's retreat and blocked enemy reinforcements. 183 Regiment 1 Battalion cooperated with 182 Regiment to capture the Jiguan Reef along the boulder and the mountain, control the key points near the ferry, build fortifications to prevent enemy reinforcements, and then destroy the remaining enemies on the island one by one.

Just as the Seventh Corps was eager to make contributions, the Golden Gate Campaign launched by the Tenth Corps failed. The Central Military Commission informed the whole army, asking all ministries and commissions to learn lessons and convey them to cadres at or above the division level. Sun Jixian, commander of the 22nd Army, and Ding Qiusheng, political commissar of the 22nd Army, for fear of affecting the combat determination of the troops, did not convey it to 6 1 division. 2 1 Teng Haiqing, the commander of the army, and Tang Guanghui, the political commissar, thought that 6 1 division had been placed under the command of the 22nd army, but it was not conveyed to them.

In this way, the sixty-first division proceeded according to the established plan, and set sail from Taohua Island on the night of165438+1October 3, and went straight to Denbu Island.
