In accordance with the Navy KKO Commander's Order No.079/SP/KKO/57, dated March 18, 1957, the duties of the Navy KKO Troops are as follows:
The Gunung Gede operation was carried out based on the Regimental Operations Order dated 19 March 1957, in just a few days, namely from 19 March 1957 to 24 March 1957. In short, the implementation of this operation was because the Mission (Task) assigned to the KKO-AL Troops had been can be achieved where gang activities around Mount Pangrango can be suppressed and neutralized. On March 19, 1957, KKO-AL troops arrived in Sukabumi and then immediately reported to the Commander of the 8.TT.III Infantry Regiment and to the 311th Army Battalion which at that time was carrying out operational duties. After reporting themselves, the KKOAL troops continued their movement to Cipanas and to Cibodas, in Cibodas this was the new Lt.KKO. Prawoto Soedibjo as Danton I explained to the members the purposethan his arrival in the area. March 20, 1957 KKO-AL Troops together with a CI Bn. 311 began moving to the high areas around Cibodas with the intention of looking for gang nests according to information obtained from local officers, but apparently during this movement no gangs were found at all, only former gang huts were found.only, which had just been abandoned by the mob, then the troops rested (overnight) on the slopes of Mount Pangrango and Mount Gede. The next day, March 21, 1957, the troops continued their movement to the top of Mount Pangrango, the journey continued to approach with closed terrain and the air was constantly foggy with very cold air. Then the gang ran away, leaving behind several victims. During the battle, important documents were seized which were then handed over to the 8th Infantry Regiment in Sukabumi.
The success of this attack was due to a sudden ambush carried out by the KKO-AL Unit where the gang had no idea that an attack would occur. This was proven when the KKOAL troops approached the gang's nest to a distance of 15 meters, and this was the opportunity for an intensive attack, so that in such a situation, the mob panicked and was devastated and left behind victims and others who were not able to run away. Furthermore, KKO-AL troops continued to pursue the remainsThe hordes fled to Pasir Datar and finally the troops were able to reach Ciheuleng Waterfall. And it was here on March 23, 1957, that a second battle occurred with the DI/TII Kartosuwiryo gang, the battle lasted approximately 10 minutes. With a quick and sure movement the mob was finally repulsed. The horde retreated to the north where there were many mountains and wild forests. With the completion of the battle at Curug Ciheuleng, the troops moved south to Pasir Datar and it turned out that during this last movement there was no armed contact. In accordance with the order issued by the 8.TT III Siliwangi Infantry Regiment, the movement of the Navy KKO Troops ended here at 20.00evening the troops returned to Sukabumi. From Sukabumi that same night at 22.00 the troops continued to return to Jakarta carried by 7 TNI AD trucks. And finally arrived in Jakarta safely at 03.00 in the morning (24 March 1957).
