Two unusual sights reward Greg for his 3 am start for a dawn patrol: a flashing lighthouse (yes, really) and the rather more dangerous ‘flaming onions’.

Diary

Sunday July 14th.  Dawn patrol 3pm – 6pm [sic; am intended].

Took off in dark with 4 Coopers and two parachute flares.

Found a hun lighthouse flashing O. South of Bac St. Maur.

Dropped the four bombs and pushed the two flares down the launching tube.

The first flare dropped straight through the tube & did not light; the second flare exploded with a flash like lightning & then hung in the air & fizzled away like a Roman candle.  Rather a washout; did not light up the ground at all. 

Saw a barge on the river and also about half a dozen transport on the road.

So the parachute flares were something of a failure.  There’s more on the lighthouse in the Squadron Record Book, which also reports the flaming onions which, curiously, Greg didn’t mention in his diary.

Lighthouse on Hill South of Bac St Maur

Can this really be plausible?  A lighthouse at Bac St Maur on the River Lys?  Well, yes, quite plausible.  But it wouldn’t have been anything to do with river traffic: it would have been an aerial lighthouse.  Both sides in the First World War used them to guide aircraft returning from missions.  According to the informative ‘Aerial Lighthouses‘ page on Mr Mycetes‘ website, something of a network of them grew up after the war as commercial air traffic became more common.  But they were largely dismantled at the beginning of the Second World War.  Afterwards they were never rebuilt, as radio and radar had taken their place.

Actually, the more difficult thing to understand is the reference to the lighthouse being on a hill south of Bac St Maur.  It’s pretty flat land round there.  The River Lys at Bac St Maur is 14 m above sea level, and going south from there the nearest high ground is near Aubers, where the 40 m contour line runs.  Aubers is about 5 miles (8km) to the south.  Greg saw the lighthouse from Estaires, almost 4 miles (6½ km) WSW of Bac St Maur.  So it seems is reasonable to think in terms of distances on this scale for the location of the lighthouse.  Near Aubers has to be a good candidate for where it was.

Flaming Onions

The War History Online website explains flaming onions as follows:

What it actually was, was a 37 mm revolving-barrel anti-aircraft gun used by the Germans. From a technical standpoint, it was a Gatling type, smooth bore, short barreled automatic revolver. Nicknamed a ‘lichtspucker’ (light spitter), it was designed to shot flares at low velocity in rapid sequence across a battle area. The gun had five barrels and had capabilities of launching 37 mm artillery shells five thousand feet. To help maximize chances of connecting with a target, all five rounds were discharged as rapidly as possible, thus producing the “flaming onion” visual and effect. Anti-aircraft artillery of the time fired very slowly. Because the flaming onion fired rapidly, many pilots thought the rounds were attached to a string and feared being shredded by it in the process. Not designed for anti-aircraft use, the weapon did not have purpose-designed ammunition, however, the flares would have been dangerous to fabric-covered aircraft.

Another variety of peril to be faced.
