Meanwhile, the other business of the Squadron continued. Capt. Archer, who was in combat action only two days ago (here), was the pilot, who flew to the (unsuccessful) defence of a balloon – probably a kite balloon – near Steenbecque:
Time: 4.50 p.m.
Locality: STEENBECQUE
Pilot: Capt. R. A. Archer, M.C.
Observer: Lieut. F. B. Sagar
Saw a hostile Scout flying towards Balloon. Decided to attack if I got a chance. E.A. was steering a roundabout course which enabled us to reach Balloon almost as soon as E.A. Dived on E.A. firing Vickers at him until a No 3 stoppage occurred. Turned to give Observer a shot and he put in about 50 rounds. In the meantime the balloon was lit and the E.A. turned home. Closest range Vickers about 150 yards. Lewis about 200 yards. E.A. did not appear to try to fire on us.
No 3 Stoppage
According to the Great War Forum’s user Andrew Upton in a post of 20 November 2016, the most common reason for a No 3 (3rd position) stoppage on the Vickers machine gun is a feed fault, but there are other possibilities, including
Insufficient headspace,
Friction in the lock,
Bent or damaged long spacers (every three rounds),
Thick-rimmed cartridge,
Stuck or “frozen” gib, overly stiff gib spring, or roughness or burrs on extractor face, and
Not enough tension on the recoil spring.
Steenbecque
Steenbecque is just north of the Nieppe Forest, 4½ miles (7 km) northwest of Aire-sur-la-Lys:
Lts Puckle (Pilot) and Nicolson (Observer) of 42 Sqn RAF again saw aerial combat, only three days after their last encounter. This time they were on photographic duty, and were incidentally attacking enemy kite balloons near Estaires when they became entangled with a couple of Albatros scouts. Presumably the job of the scouts was to defend the kite balloons.
Time: 11.35am
Locality: ESTAIRES
Pilot: Lt H. Puckle Observer: Lt J. F. W. Nicolson
Two Albatros Scouts.
While attacking 4 E.K.B. at R.4, R.11, R.17, G.20, two Albatross Scouts were seen by Observer to be climbing up to machine about 1500 feet below. Observer fired a drum of Lewis into nearest E.A. which spun down, flattened out and flew away East. The other Scout also flew away.
Estaires
The map squares R.4, R.11, R.17 and G.20 (1:40,000 sheets 36A and 36) are either side of Estaires, which is in the Département du Nord on the River Lys, about 15 miles (24 km) west of Lille:
Although Greg had not yet got to France, this photograph dated 15 May 1918 of a kite balloon in operation at Bray-sur-Somme somehow found its way into his collection.
But where is the balloon, you might ask? About half way down the full image, and about one third in from the left hand edge. Here is a magnified detail:
Kite balloons are shaped to be more aerodynamically stable than near-spherical balloons, and so can withstand more windy conditions. Both sides made good use of balloons as observation platforms, for artillery support and general reconnaissance. The balloon shown here is probably a German copy of a French Caquot design, designated Typ Ae, standing for Achthundert english. The Achthundert is a reference to the ~800 m³ capacity of the balloon, which was based on a captured British model.
Here it is at closer quarters:
The position of the balloon was, when the photograph was taken, some 4½ miles/7 km ESE of the closest point of the forward positions of the British front line between Morlancourt and Sailly-le-Sec, and so was presumably intended to gather information from that direction.
As a comparison of the following two images shows, the landscape hasn’t changed a great deal in the intervening 100 years. The settlement at the bottom right of the old photo is La Neuville-lès-Bray, which hasn’t expanded much. Neither has Etinehem in the top right. And the courses of the Somme and the Canal de la Somme that joins it from the bottom centre of the photo are much the same.
