The drop zone code-named “Kos” (Ref. No. 2844) was located 24 km northeast of Kraków. In the records of Section VI of the Commander-in-Chief’s Staff, it was listed under numbers 309 and 407. There is no data on contact addresses for parachutists. The drop zone was originally designated as a site capable of receiving material from only one aircraft; it was subsequently upgraded to a bastion capable of receiving drops from two and then three aircraft.
The “Kos” site was on alert for the first time during the period of April 16–18, and then from April 20 to 25, 1944. On the night of April 24, two Handley Page Halifax aircraft with British crews flew over the drop zone (JP-162 “N” W/O J. D. McColl and HR-680 “D” F/L A. R. Blynn, both loaded in a 0-12-12 configuration). Unfortunately, neither completed the mission. The next alert period fell on May 20–22 and 27–29, 1944. On the night of May 21, 1944, two Handley Page Halifax aircraft with Polish crews took off for a flight over occupied Poland (JP-236 “A” piloted by Senior Sergeant Pilot (F/S) Wacław Niezręcki and JP-222 “E” piloted by Captain Pilot (F/L) Gerard Kunowski). The first to arrive over the “Kos” drop zone was Senior Sergeant Pilot (F/S) Wacław Niezręcki’s aircraft, which dropped 12 containers and 12 packages in two passes. A few minutes later, the second aircraft arrived and dropped the parachutist team of Captain Tomasz Wierzejski, code name “Zagroda-2,” as part of Operation “Weller 29.” Jumping with them was General Leopold Okulicki, code names “Kobra-2,” “Niedźwiadek,” “Termit” — the last commander of the Home Army. The Kraków District Home Army Command confirmed receipt of 6 parachutists, 24 containers, and 10 packages (6 packages from the first drop were not found).
On October 10, 1993, a ceremony was held in the village of Wierzbno in the commune of Koniusza (now Lesser Poland Voivodeship, Proszowice district) to unveil a monument dedicated to General Leopold Okulicki, code name “Niedźwiadek,” and the other Silent Unseen paratroopers dropped at the “Kos” site.
The ceremony was attended by, among others: Adam Bień — Deputy Government Delegate to the Homeland during the occupation, Brigadier General Bohdan Zieliński, code name “Tytus,” Brigadier General Franciszek Kamiński — brother of General Okulicki code name “Niedźwiadek,” the wife of Second Lieutenant Zbigniew Waruszyński code name “Dewajtis-2,” and delegations from the former voivodeships of Kraków, Tarnów, Rzeszów, and Nowy Sącz. Home Army soldiers from all over Poland also attended, including a delegation of the “Parasol” Battalion from Warsaw.
The monument, designed by Karol Jakubowski, has the shape of an obelisk tapering like an aircraft wing. It bears an inscription plaque with the names of the parachutists dropped as part of Operation Weller 29, signed “Fellow Countrymen,” and the emblem of the Silent Unseen, the paratroopers of the Home Army.
At the site commemorating Weller 29, annual ceremonies are held at the monument to mark the anniversary of the Silent Unseen drop. They are organized by municipal and county local government authorities with the participation of children and youth from nearby schools and scouting organizations, as well as invited guests.
