Background

The dispute between Ecuador and Peru dates from 1840. Much of the dispute revolved around whether Ecuador's territory extended beyond the Andes

Subsequently, Ecuador contended that the Pedemonte-Mosquera Protocol was signed in 1830 as a continuation of the Gual-Larrea Treaty, but Peru disputes the validity of this protocol and even questions its existence, since the original document cannot be found.

The Salomón–Lozano Treaty was unpopular in Ecuador as well, which found itself surrounded on the east by Peru, which claimed the territory as an integral part of its Republic. Further adding to Ecuador's problems, now Colombian authorities also recognized Peru's territorial aspirations as legitimate.

Preparing for war

An agreement was signed in 1936 which recognized territories in de facto possession by each country. The resulting border is known as the 1936 status quo border line.

However, by 1938 both nations were once again holding minor border skirmishes. That same year, the entire Ecuadorian Cabinet

, there were public demonstrations of people chanting "Down With Peru! Long Live Ecuador!."

Peru's response to the events taking place in Ecuador was provided by foreign minister Carlos Concha, who stated, "In Peru we have not yet lost our heads. Our country is in a process of prosperous development and the Government heads would have to be completely mad to think of war." The social situation of Peru at that time was undergoing major changes, with the social reforms begun by president Augusto B. Leguia

 (which were aimed at improving roads, sanitation, industrial development, and promoting the general welfare of Peru's Native American population) being continued by president General Oscar Benavides. Economically, Peru claimed to be attempting to run on a balanced budget, but Peru still held a large debt despite its positive foreign trade. However, despite these claims, Peru also began to mobilize its troops to its border with Ecuador in order to match the Ecuadorian troops which had been deployed to the dispute zone.

On January 11, 1941, alleging that the Ecuadorians had been staging incursions and even occupations of the Peruvian territory of Zarumilla, the President of Peru, Manuel Prado, ordered the formation of the North Grouping, a military unit in charge of the Northern Operational Theater.

Ecuador

According to the testimony of Col. Luis Rodríguez, the Ecuadorian forces at the disposal of the Army Border Command in El Oro (Lieutenant Colonel Octavio A. Ochoa) after the incidents of July 5 and 6 were as follows:
  • Forces deployed along the Zarumilla river: 3 superior officers, 33 officers, and 743 men, organized as follows:
    • "Cayambe" Battalion: 2 superior officers, 22 Officers, 490 soldiers.
    • "Montecristi" Battalion: 1 superior officer, 11 Officers, 253 soldiers.

  • Forces deployed in the immediate rear: 4 superior officers, 40 officers, 28 soldiers, 93 volunteers, 500 carabineros (a paramilitary Government force), organized as follows:
    • At Arenillas: 2 superior officers, 3 Officers, 14 soldiers.
    • At Santa Rosa: 2 superior officers, 1 Officer, 18 soldiers, plus the 93 volunteers, and the 500 carabineros.

Peru

As a result of the rising tensions on the border during 1939 and 1940, the Peruvian President Manuel Prado authorized in December 1940 the creation of the Agrupamiento del Norte (Northern Army Detachment). By July 1941, this unit was ready to begin active military operations.

Figures for total strength of the Agrupamiento del Norte at the beginning of offensive operations have been put at 11,500 to 13,000 men.

War

The accounts as to which side fired the first shot vary considerably to this day. According to Peru's version Ecuadorian troops invaded Peruvian territory in the Zarumilla province, which started a battle that spread to a zone known as Quebrada Seca (dry barren). But Ecuador's version is that Peru took a series of incidents between border patrols as a pretext to invade Ecuador, with the intention of forcing it to sign a clear border agreement. They argue that the clear disparity of military presence in the region between the two countries supports this version.

The first clashes occurred on Saturday, July 5, 1941.
  • According to Peruvian accounts, some Ecuadorian troops from the garrison of Huaquillas

     river, which then served as the status quo line in the extreme left of the Ecuadorian-Peruvian border, crossed into the Peruvian border post at Aguas Verdes, a town directly in front of Huaquillas, and opened fire on a Peruvian patrol. These troops were then followed by some 200 Ecuadorian armed men, which attacked the Police station at Aguas Verdes, to which the Peruvians reacted by sending an infantry company to Aguas Verdes and repulsing the Ecuadorians back across the Zarumilla. The fighting then spread to the entire border area along the Zarumilla river. By July 6, the Peruvian aviation was conducting air-strikes against the Ecuadorian border posts along the river.

  • According to Ecuadorian Col. Luis A. Rodríguez, commander of the Ecuadorian forces defending El Oro during the war, the incidents of July 5 started when an Ecuadorian border patrol found some Peruvian civilians, protected by policemen, clearing a patch of land on the Ecuadorian side of the river. Upon seeing the patrol, the Peruvian policemen opened fire, killing one soldier. This was followed by the widespread exchange of fire between troops on the opposing banks of the Zarumilla, while two Ecuadorian officers sent to Aguas Verdes to speak with the Peruvian local commanding officer were told by Peruvian authorities to go back to their lines.


Regardless, the much larger and better equipped Peruvian force of 13,000 men quickly overwhelmed the approximately 1,800 Ecuadorian covering forces, driving them back from the Zarumilla and invading the Ecuadorian province of El Oro

 on January 29, 1942, and Peruvian forces subsequently withdrew. Nonetheless, during the retreat several attacks were made against the Peruvian military, and a series of lives were lost during the process.

Aftermath

The placement of the border markers along the definitive border line indicated by the Rio Protocol was not concluded when the Ecuadorians withdrew from the demarcation commissions in 1948, arguing inconsistencies between the geographical realities on the ground and the instructions of the Protocol, a situation that according to Ecuador made it impossible to implement the Protocol until Peru agreed to negotiate a proper line in the affected area. Thus, some 78 km of the Ecuadorian-Peruvian border were left unmarked for the next fifty years, causing continuous diplomatic and military crisis between the two countries.

    , was hit while performing a low-level attack on an Ecuadorian border post on the banks of the Zarumilla river. According to traditional Peruvian accounts, Quiñones, upon being hit, flew his aircraft directly toward an Ecuadorian anti-aircraft position and crashed against it. He was promoted posthumously to Captain, and is considered today a National Hero in Peru.

  • Ecuadorian wartime records of the downing differ greatly from Peruvian ones as Ecuador did not have any anti-aircraft guns located in the area, and the limited artillery located at the Machala was, due to a mistake by the minister of defence, useless as he ordered the wrong calibre of ammunition to be delivered to the units.
