Guingouin was mobilised in the rank of second class in 1939. He sustained an eyebrow injury on 18 June 1940, and was cared for in the
Moulins military hospital in
Allier, which he left voluntarily in order to avoid being taken prisoner. On returning to
Saint-Gilles-les-Forêts, he secretly went back to his activities as a communist fighter, and wrote in 1940 a "call to the struggle". In September 1940, recalled from his teaching functions, he got back in contact with the underground communist party machinery and became federal secretary of Haute-Vienne. However, he decided not to circulate the 9th issue of the "Life of the party" communist party bulletin, which declared "We must be without hate towards the German soldiers. We are against
de Gaulle and the capitalist clan whose interests are linked to
Vichy In January 1941 Guingouin published the first issue of the
Travailleur limousin (Limousin worker) underground journal. He later wrote that he held off from attacking de Gaulle or the
United Kingdom, breaking with the official party line. In April 1941 he joined the maquis, which astonished Gabriel Roucaute, one of the party leadership's representatives in the
zone libre. During the night of 30 September to 1 October, Guingouin organised the first armed requisitioning of ration cards, which would earn him a forced labour sentence
in absentia at the hands of a military court in January 1942. He named his first armed groups "Francs Tireurs", at a time when the
Francs-Tireurs et Partisans had not yet been created. In March 1942, when the communists joined the armed struggle in earnest, Roucaute ordered him to stop his operations. Guingouin refused, and relations with the party became strained. After this, he joined with the FTPF. Nicknamed
Lo Grand (the Great) by the locals, Guingouin organised his first
maquis, notably in
Châteauneuf-la-Forêt. Certain types of operations under his command led to him being titled "prefect" of the maquis: in December 1942, he attempted to put a stop to hay and wheat requisitioning by blowing up the baler at Eymoutiers. He formed a fixed unit, the 1st
Brigade de Marche Limousine, and mobile "flying" units with varying effectiveness. In February 1943, he carried out a solo operation to break into a German ammunition warehouse disguised as a woman to hide his identity. Guingouin's unit sabotaged and destroyed the Bussy-Varache viaduct on the Limoges-
Ussel on 13 March 1943; the viaduct was not reconstructed until after the war. On the night of May 9, 1943, at the request of the English, Guingouin personally led a
commando which sabotaged the boilers at the
rubber factory in
le Palais-sur-Vienne near
Limoges, thereby halting the production of France's second largest rubber factory for five months. While returning, the commando narrowly missed an ambush by the police. On 14 July 1943, the subterranean cable linking the Bordeaux
submarine base with
Berlin was sabotaged in Limousin. Following this operation, the Germans demanded that serious measures be enforced in what they called "little Russia". Under the command of General Bois 15 guard squadrons, 12 squadrons of the GMT and residual gendarmerie forces were sent in to "maintain order", without significant success. In August 1943, Guingouin undertook anew to prevent wheat deliveries to the Germans by destroying the combines. As "prefect of the maquis", he regulated agricultural sales as well as boltage rates for bread manufacturing in order to counter the
black market and
fraud. At the same time he received the first parachute drops of armaments from the British
Special Operations Executive. During January 1944, he brought together 120 volunteers at the château de Ribérie for military training. Shortly afterward, the German General Walter Brehmer attacked Guingouin's territory; Guingouin refused battle and dispersed his units. In May 1944, Haute-Vienne had about 8,000 armed men, the most of any department in France. After the amalgamation of the
Armée Secrète,
ORA and FTPF resistance movements into the new
French Forces of the Interior the structures of the armed resistance remained confused, so that in spite of the unification, the FTPF retained the possibility of acting autonomously. Photos of the maquis and its leader were taken at this time by the photographer
Izis Bidermanas who had also taken up arms. At the start of July 1944, Guingouin was warned that a German offensive was being prepared against his maquis. On the 17th, the 1st brigade was attacked by the German brigade of General
Curt von Jesser with a strength of 500 vehicles, supported by various reinforcements. This triggered the battle of
Mont Gargan. The maquis lost 97 men (38 dead, 5 missing, 54 wounded) against 342 killed and wounded on the German side. It was one of the rare occasions when the resistance fought against the
Wehrmacht in open battle. At the beginning of June 1944, Guingouin was ordered to take Limoges by
Léon Mauvais, an important communist party official and head of the FTP in the zone Sud. Guingouin refused, considering the operation premature and dangerous for the general population. In support of his decision he cited the tragic example of the premature liberation of
Tulle, where, in
reprisals, 99 men had been hanged from balconies on the main road of the city, and 101 others deported. Guingouin's refusal would have grave consequences for relations between Guingouin and the communist party hierarchy. On 21 August, Guingouin encircled Limoges, and received from Jean d'Albis the surrender of General Gleiniger's men, with minimal bloodshed. Guingouin was appointed lieutenant-colonel of the French Forces of the Interior. Following this, Guingouin would be accused of being directly or indirectly responsible for extortion which accompanied the liberation and
"épuration" (cleansing) of Limoges and Limousin. According to Henri Amouroux, Guingouin had "45 people tried and sentenced to death in a week, of whom only one escaped", and that the first to be accused did not have anyone represent them in defense, and "worked from six to twelve hours per day, including Saturday and Sunday." Guingouin was also accused of acquiring loot from a former youth work camp at
Chamberet which would result in 6 executions, including three members of the
Armée secrète. == Pariah of the Communist Party ==
