Command of the No. 313 Squadron was at the beginning given to S/Ldr Gordon L. Sinclair, DFC, who had
fought with Czech pilots during his previous assignment
as a flight leader of the No. 310 Czechoslovak Squadron
in the course of the Battle of Britain.

The first Czechoslovak commander of the No. 313 Squadron
was S/Ldr Josef Jaske. In December 1941 he was succeeded
by S/Ldr Karel Mrazek.
intense combat during the Battle of Britain. By September, 1940, he had already accumulated seven kills. He arrived at No.313 Squadron as one of the
first to do so, and this was as early as May 12th, 1941. Thanks to his tendency
to follow regulations to the letter, and for his overall reticence, a quality quite
contrary to those of the Czech pilots, he acquired the nickname ‘White Devil’.
A Flight lead was given to F/Lt Karel Mrazek (who came from No.257
Squadron on May 17th) and to the Brit F/Lt John ‘Iggie’ Kilmartin, DFC (June
4th from No.602 Squadron). Both were experienced veterans of the Battles
of France and Britain. The generally well-liked Kilmartin was then one of the
RAF’s aces with thirteen kills to his credit. Mrazek, among the most capable
of professional Officers of the Czechoslovak Air Force, ultimately went far in
his career. He went on to lead not only the Flight, but took over the Squadron
command after six months, and after another half year, he took over the reigns of the Czechoslovak Air Wing. From the beginning, he named Fajtl as his
The same sort of Czech and Brit co-leadership set up applied to B Flight.
These were F/Lt Jan Cermak (who came from No.312 Squadron on May 19th)
and F/Lt Thomas W. Gillen (June 4th from No.403 Squadron), both coming
with previous combat experience. Other major functions, such as those of Press and Technical Officers, were split equally at first. As it was with the other
three Czechoslovak fighter squadrons in the RAF, the British counterparts to
the Czechoslovak commanders were to withdraw as the command structures
normalized according to RAF requirements. 5
When it came to pilots, it should be said that, although the unit was newly
activated, they were no greenhorns. A large number of them came with Battle of Britain experience, and some even having seen combat in the doomed
Battle of France. It’s ‘rookie’ status only stemmed from its having been newly
On the day of Fajtl’s arrival at No. 313 Squadron it’s first member was killed - Sgt Josef
Gutvald (* December 21, 1911, Trest, + May 25, 1941, Uckerby at Sconton) who had
arrived several days earlier from No. 46 Squadron. He was performing a high altitude
training flight climbing to 7000 m and vectoring to the home base (homing practice).
At 17:30, after twentyfive minutes flight due to the unknown circumstances he crashed
into the ground and perished. Upon impact 1.5 km west of the Sconton railway station
(Yorkshire) his Spitfire Mk.Ia R7163 (RY-S) Bridgewater completely disintengrated into
pieces. Probable cause of a disaster could have been pilot’s loss of consciousess due to
malfunctioned oxygen mask or some other technical fault.

This, however, applied mainly to the pilots. The groundcrew, composed almost entirely of Brits, were fresh recruits. This presented a problem, because
many of the airframe and engine mechanics went through an accelerated and
abbreviated training program and had little to no real world experience.
With the lack of military experience and its associated behaviors and protocols, the Czechoslovak officers were very irritated. However, the situation
did gradually improve. Much of the credit for this goes to the experience
and personality of the chief mechanic, F/Sgt Rogers, who was able meet the
problems faced head on, but very calmly and practically. Within two years,
the situation completely turned around. The originally inexperienced personnel
would become the best team of groundcrew in Fighter Command by 1943!
The first of the Czechoslovak fighter squadrons in the RAF to be equipped
with the Spitfire 7 was No.313. Initial equipment consisted of older Spitfire
Mk.Is armed with eight Colt Browning 7.7mm machine guns and powered by
