Cenepa War
Figures given for losses during the Cenepa War vary widely, especially regarding human casualties. Ecuadorian military sources put the casualties at 34 killed recognized by Comando Conjunto de las FFAA del Ecuador and 154 killed and wounded recognized by Asociación de ex combatientes del Cenepa, Quito, Ecuador. As of February 2005, an Ecuadorian Cenepa war veterans' association had a membership of 131 ex-combatants, some of them with long-term health disorders caused by the war.
ALDHU, a human rights NGO, has put the total number of mortal casualties for both sides at around 500. This figure was also given by Ecuadorian senior officers after the war, reflecting the fact that Peruvians found themselves attacking well-protected Ecuadorian positions and subjected to continuous ambushes and well-aimed artillery and rocket fire from the heights of the Condor range.
Battle of Lesnaya
Swedish casualties, according to General Adam Ludwig Lewenhaupt, numbered not much more than 1,000 men during the battle itself, with a total of 1,674 dead and captured in the battle "and" on the road towards Propoisk. Overall, he claims, the casualties could not exceed 3,000 men in the battle "and" the following days (with the events at Propoisk), however, these figures are regarded as questionable and too low, according to the Swedish and Russian writers Einar Lyth and Pavel Konovalchuk. According to Lewenhaupt's Lieutenant, Friedrich Christoph von Weihe, the Swedish losses in killed amounted to 2,000 men in the battle along with a number of captured. In total, Weihe estimates that there were 3,800 Swedish casualties in the battle "and" in the following days. Robert Petre, a second-lieutenant in the Swedish army and veteran soldier in the Hälsinge regiment, however, puts the total Swedish casualties at 4,549 men. According to the Russian official description regarding the Swedish casualties, 8,000 were killed on the battlefield and a total of 3,500 captured soon thereafter, other sources claim 6,700 Swedes killed and wounded in the battle and another 5,000 in the pursuit, numbers which are proven unrealistic and impossible in regards to the initial strength of the army.
Later attempts have been made by authors trying to calculate the Swedish casualties using the initial strength of the force as basis. Lewenhaupt said there were less than 10,914 men present under his command, Weihe and Petre in turn claimed there were 11,450 and 12,950 men, respectively, at the beginning of the march from Riga in early July. Nicholas Dorrell, a student in history, estimates the Swedish force at about 12,500 men strong in the battle, in an attempt to apply "marching losses" to the army. In regards to this, 6,500 Swedes were patterned after the battle in ""condition to fight"" at Propoisk, according to Petre (of which above 6,000 made it to the main army under Charles XII), about 1,000–1,500 wounded and sick Swedish soldiers along with some stragglers were left at Propoisk, of which the majority were later either killed or captured by Russian cavalry, according to Russian sources. Between 2,500 and 3,300 soldiers went missing, of which most marched on their own back towards Sweden, between 1,250 and 1,500 of these arrived and the other perished during the march due to wounds, sickness, starvation or exhaustion, or possible Cossack attacks.
