@ tazatz, these knuckleheads are always afraid to be very specific for fear you can counter them withe facts.
Wikipedia— war of attrition as Israel has been block out of the Suez Canal
March 8, 1969: Egypt strikes the Bar Lev Line with artillery fire and airstrikes, causing heavy casualties. Israel retaliates with raids deep into Egyptian territory, causing severe damage.
March 9, 1969: The Egyptian Chief of Staff, General Abdul Munim Riad, is killed in an Israeli mortar attack while visiting the front lines along the Suez Canal.
May–July 1969: Heavy fighting takes place between Israeli and Egyptian forces. Israel loses 47 dead and 157 wounded, while Egyptian casualties are far heavier.
July 18, 1969: Egyptian commandos raid Israeli military installations in Sinai.
July 19–20, 1969: Operation Bulmus 6 – Israeli Shayetet 13 and Sayeret Matkal commandos raid Green Island, resulting in the total destruction of the Egyptian facility. Six Israeli soldiers and 80 Egyptian soldiers are killed. Some Egyptian casualties are caused by their own artillery.
July 20–28, 1969: Operation Boxer – Nearly the entire Israeli Air Force attacks the northern sector of the Canal, destroying anti-aircraft positions, tanks and artillery, and shooting down eight Egyptian aircraft. An estimated 300 Egyptian soldiers are killed, and Egyptian positions are seriously damaged. Israeli losses amount to two aircraft. Egyptian artillery fire is reduced somewhat. However, shelling with lighter weapons, particularly mortars, continues.
July–December 1969: Israel carries out its “flying artillery” campaign, employing widespread air raids against Egyptian positions in the Suez Canal. In August alone, the Israeli Air Force flew about 1,000 combat sorties against Egypt, destroying dozens of SAM sites and shooting down 21 aircraft for the loss of three aircraft. Israeli jets flew low to avoid Egypt’s SAM-2 missile defenses. Soviet advisers sometimes counted up to eighty Israeli sorties per day in a single sector. Egypt’s SAM-2 batteries were severely mauled, causing Egyptian artillery crews to become more reluctant to engage and reveal their positions, enabling Israeli tanks to emerge from cover and take direct aim at Egyptian positions. Several Soviet advisors to Egyptian forces were killed in the bombing campaign. The Soviets subsequently introduced the Strela-2 missile to target high-flying aircraft, shooting down an Israeli A-4 Skyhawk on August 19.
I am guessing he might be referring to 9 September 1969 – Operation Raviv: During the War of Attrition, an IDF armored force is landed on the Egyptian shore of the Suez canal disguised as an Egyptian military force, inside six Egyptian tanks and three Egyptian armored personnel carriers which had previously been captured by the IDF. Masquerading as an Egyptian force, the raiders meet no significant resistance. The IDF armored force raids Egyptian military bases along the west coast of the Gulf of Suez attacking Egyptian radar stations, military vehicles and other military targets. The Egyptian Army suffers an estimated 100-200 casualties and had 12 outposts destroyed. The Israeli forces suffers no losses.
