A visit to Florence, the birthplace of ace Giulio Lega



Since I’m on a short vacation in Italy, and more specifically Florence, it seemed a good idea to spend an evening after a nice dinner to write a paragraph or so about a First World War ace from this lovely city: Giulio Lega.

Lega was born in Florence on November 12, 1892. He studied medicine when the war broke out in Europe, but he was accepted for officer’s training in 1915 as Italy joined the conflict. Giulio Lega was a tall man for his time , and he was selected as an “extended infantryman” with the Grenadiers of the 2o Reggimento.

Giulio Lega fought with his regiment at the Fourth Battle of the Isonzo between November 10 and December 2, 1915. The fighting was bitter and inconclusive, but on November 20, Lega was awarded the War Merit Cross for valor. Lega continued fighting in north-eastern Italy, and he was awarded the Bronze Medal for Military Valor after close-combat fighting that month. The medal was awarded on the battlefield on May 30, 1916.

That summer, Lega volunteered to be trained as an aviator. He qualified as a pilot on September 1, 1916, and he was given his pilot’s license on November 1, 1916. Lega finished up his pilot’s training on January 30, 1917, and he was posted to the 21a Squadriglia, a reconnaissance unit, where he qualified on Savoia-Pomilio SP.2 two-seaters on February 14, 1917. He was also promoted to Tenente. Lega continued serving as a reconnaissance pilot between May and November of 1917, and he was awarded the Silver Medal for Military Valor for his service. He remained with the 21a Squadriglia until it was withdrawn after the Battle of Capporetto, after which he was selected for fighter pilot training.

On November 16, 1917, Lega began fighter pilot training at Malpensa outside Milan after which he went for gunnery training. He passed on December 27, but only with a “mediocre” rating. Lega’s next posting would be with the 76a Squadriglia, and he would fly in all 46 combat sorties with the squadron. His first victory came near Col d’Asiago on March 17, a victory he shared with two other Italian pilots, and on March 25 he split his second victory over Montello with pilots Fanti and Retinò. The final Austro-Hungarian offensive led to a bout of activity, and a third shared victory came over Passagno on June 24 against a Hansa-Brandenburg C.I from Flik 2d. The next day, June 25, saw even more action around 1030 as Lega shot down an unidentified enemy scout over Mareno di Piave together with Tenente Silvio Scaroni and Sergente Romolo Ticconi, both of whom were aces. Lega finished off the scrap by shooting down an Albatros D.III, once again together with Scaroni and Ticconi. This action earned Lega the Silver Medal for Valor. In July of 1918, Lega was transferred to the 81a Squadriglia, and he served with this unit up to the end of the war.

While flying with the 76a Squadriglia, Lega flew a silver dope-colored Hanriot armed with two Vickers machine guns instead of one. This reduced the maneuverability of the Hanriot, but apparently not enough to have several skilled Italian pilots choose this option for increased firepower. The personal aircraft of Lega was adorned with a flaming red grenade to honor his initial service as a grenadier in the 2o Reggimento.

Following the end of the First World War, Lega graduated from the University of Bologna in July of 1920. He remained in the Air Force Reserves and served with the Servizi Aerei Speciali  during the Second World War. He spent much of his subsequent career with the Italian Chamber of Commerce, and when he died on 11 July 1973, he was still a medical consultant to the Italian parliament.

French Incendiary Ammunition during WW1

Observation balloons were very important for directing fire during of the First World War, and this made them prime targets for aviators of all nations. Many methods were used to destroy the balloons, including hooks, bombs, explosive arrows and rockets. However, by mid-1917, most nations were using various forms of incendiary ammunition. The British had Buckingham incendiary rounds as well as the explosive Brock and Pomeroy rounds. Then there was the British RTS round, which was both incendiary and explosive, and fielded in June of 1918. The Germans used incendiary Ph- (as in phosphorus) ammunition.

The French Aéronautique Militaire also required incendiary ammunition to engage observation balloons, and they found that the best way of providing enough fiery potential in a round was to increase the caliber. .303 was seen as not being a big enough caliber, so in 1917 the French introduced an 11mm Vickers machine gun, the so-called Gras Vickers, that could fire a modified version of the old 11x59R Gras rifle cartridge which contained a Desvignes Mark XI incendiary bullet. The Desvignes was actually a tracer bullet, but the size of the round enabled a long and powerful burn. Despite the caliber, the bullet was lighter, and it thus had greater muzzle velocity, in this case some 600 m/s. The Gras Vickers was mainly fitted to SPAD XIII scouts, often with one 11mm and one .303 Vickers in the nose.



The Gras Vickers was also used by the United States Army Air Service (USAAS), mainly on Nieuport 28 aircraft, and it was introduced by the Americans in late 1917. The Americans converted Vickers machine guns that were chambered for a Russian 7.62x54R round as part of an order that had been cancelled following the Russian Revolution, and they also introduced a heavier bullet with a weight of 17.5 g. However, this was not popular due to the heavier recoil, which caused excessive vibration while firing the gun, but the effect of the High Explosive 11mm round was still in demand, especially against ground targets, so the round remained in production even as rifle-caliber incendiary rounds became available to the USAAS. Some 500,000 11mm rounds were manufactured by the Americans up to the early 1920s, when the round was discontinued. The Gras Vickers is claimed to have been influential in the design of the .50 Browning M2 machine gun.

Belgian ace and balloon-buster Willy Coppens had the Gras Vickers fitted to his Hanriot HD.1 scout No.17, one of several Hanriots that Coppens used. He held this conversion in high regard, and at least one other Hanriot may have been armed with a Gras Vickers, although the Belgians did not manufacture the gun. A few Gras Vickers were also used by the RFC, RNAS and eventually the RAF. The last official use was in Yemen in the 1950s.
