This is the report of Oberleutnant zur See Jacques von Roques
and Obermaschinistenmaat Friedrich Stöckler
from 12-09-1915 (Gregorian calendar), concerning the sinking of the sailing ship “Ila
” in the Gulf of Riga
Libau, 15 September 1915
: Flight to Dünamünde – Riga
, Bomb shipyard of Ziese
and other important spots.
: D270, 160 HP Motor, 250 Liter petrol for 6 hours.
: Ober Leutnant zur See von Roques
, Observer Obermachinistenmaat der Reserve Stöckler
Start on 12-9-1915 5h.30 am in the harbor of Windau
. Weather clear, Wind North 1 – 2. At the same time 5 other planes start with the same order.
Flight along the coast near Domesnäs
; north from Irben two hostile destroyers are sighted. Altitude 1400 metres.
6h.45 flew from Domesnäs
, 135 degrees. Close to Domesnäs
a thick cloudlayer began, which reached to Dünamünde
. Here the 5 other planes lost their way, got disorientated and descended below the clouds.
7h.45 the coast came in sight through the clouds and in front of us we saw Dünamünde
. Altitude 1900 metres.
and surrounding area was only partly covered with clouds. In the harbor lay no war vessel , only several sailing ships. Four small harbor steamers sailed between Riga
. Because we couldn’t recognize the shipyard Ziese
immediately, we flew for a long time above Riga
and shot pictures. After recognizing the shipyard, we dropped 2 bombs. We couldn’t see if we had success, because a cloud got in the way. During the second attack we dropped 6 bombs; 3 of them fell on a workshop building and 3 on the slipways. The workshop started to burn. 8h.45 we flew northern course, away from Dünamünde
. 9h.30 we sighted through a gap in the clouds a two-masted schooner with a tugboat. I went down to 30 metres and circled around them.
After several warning shots with my rifle I ordered the tugboat to stop. After he casted off the sailing ship, I landed and taxied to the schooner. As I feared that the tugboat would ram the plane, I ordered my observer to fire several shots at him; one of the shots hit the machine. I fired several shots with my pistol at the sailing ship. On both ships the crew came on deck; raised their arms and waved as sign of surrender with several garments. The schooner lowered the longboat immediately; the 5 men strong crew left the ship and came to the plane. I sent my observer with this boat to the tugboat with the order to sink the sailing ship, because it transported iron from Gotland
took over command of the tugboat, went long side of the schooner and let the people fetch their personal belongings. One of the crewmen was ordered into the loadroom, where he had to make a hole in the bottom. Hereafter Stöckler
came back to the plane. At 10u.00 the sailing ship sank; the tugboat was released and I sent the people off.
The sailing ship was the Russian two-masted schooner “Ila
”, home harbor Windau
; cargo about 80 tons.
Oberleutnant zur See.
On 30 October 1915 von Roques
were captured by the Russians. Their plane (Brandenburg W. nr. 473) was forced to land by torpedo-boat destroyer Moskvityanain
, after the water pipe to the engine was cut by a bullet.
