Hamilton shipped out to England in late 1917 where he trained in early 1918 in an Avro 504, perhaps at RFC Bramham Moor which was then renamed RAF Tadcaster, near Bramham cum Oglethorpe in Yorkshire. Hamilton was temporarily posted as a first lieutenant to United Kingdom No. 3 Squadron, Royal Flying Corps, on 2 March 1918 He first scored as a combat pilot on 11 April 1918, flying the Sopwith Camel against his first German opponent, an LVG C.VI observation aircraft. The next day he made his second aerial kill; his third a week later. On 20 April he was flying at the tail end of 'C' flight when his commander Richard Raymond-Barker was attacked and killed by Manfred von Richthofen, known as the Red Baron. From far away Hamilton saw Richthofen shoot down a second aviator, then Hamilton was near enough to engage a blue Fokker Dr.I triplane, expending more than 300 rounds at it after which it went into a dive and spin, but Hamilton's own maneuvers prevented him from seeing what happened to it. Hamilton returned to base and claimed a kill but it was never confirmed—all of Richthofen's flight had returned safe from the engagement. On 3 June 1918, Hamilton became an ace, scoring his fifth confirmed victory. Hamilton was assigned to the USAS 17th Aero Squadron to help them complete their training. When they moved into combat, he was one of their Flight Commanders. In his service he downed three enemy aircraft and two observation balloons, becoming a double ace—once flying under RFC command and once again for USAS. His first USAS victory on 7 August was during an offensive patrol; the squadron was flying high at when they noticed eight Fokker D.VIIs well below them over Armentières. The 17th squadron dove to attack and Hamilton downed an enemy aircraft after firing 200 rounds. On Hamilton's final mission he was paired with Lt. Jesse F. Campbell to bomb and strafe transports along the Bapaume–Cambrai road, to strafe enemy troops in retreat and to attack an observation balloon that had been spotted to the north. After dropping their bombs on a small building and transports, Campbell and Hamilton turned to bust the balloon. Hamilton sprayed the balloon with machine gun rounds, and its German observer officer was seen to jump from the basket as the balloon exploded in flame. Hamilton was then killed by defensive fire from ground forces.
Distinguished Service Cross The Distinguished Service Cross is presented to Lloyd A. Hamilton, First Lieutenant, U.S. Army, for extraordinary heroism in action at Varssenaere, Belgium, August 13, 1918. Leading a low bombing attack on a German aerodrome, 30 miles behind the line, Lieutenant Hamilton destroyed the hangars on the north side of the aerodrome and then attacked a row of enemy machines, flying as low as 20 feet from the ground despite intense machine-gun fire, and setting fire to three of the German planes. He then turned and fired bursts through the windows of the chateau in which the German pilots were quartered, 26 of whom were afterwards reported killed. General Orders No. 20, W.D., 1919. Distinguished Flying Cross On 13 August 1918, Lt. Hamilton led his flight on a special mission against Varssenaere aerodrome. He dropped four bombs from 200 feet on some aeroplane hangars, making two direct hits and causing a large amount of damage. He then machine gunned the German officers' billets and made four circuits of the aerodrome, shooting up various targets. On the first circuit, he destroyed one EA on the ground which burst into flames when he shot it up. On the third circuit he repeated this performance, setting afire another Fokker biplane. His dash and skill very materially helped in the success of the operation. In addition this officer destroyed a Fokker biplane over Armentières on 7 August 1918. On 12 July he brought down two EA in flames and on two other occasions has driven down out of control enemy machines. He is an excellent patrol leader.
