October 3 in Military History — On This Day

The Siege and Relief of Leiden

With a third of Leiden's people dead of hunger and plague and the city refusing to surrender, William of Orange did the unthinkable: he broke the dikes and let the sea into Holland, drowning the harvest to float a fleet of shallow-draft barges across the flooded fields to the walls. The wind held, the water rose, and the Sea Beggars sailed over the drowned countryside into the city. The Spanish, unable to fight boats, withdrew.

The war's defining image and the birth of the Dutch Water Line — a country that could turn itself into a sea rather than surrender. Leiden's reward was a university, founded in 1575 and shortly one of Europe's finest, and the herring and white bread of the relief are still eaten there every October 3. It also set the strategic logic of the entire war: the Dutch could not beat the tercios, but they could drown the ground under them.

Battle of Kamdesh

A force of roughly 300 Taliban fighters attacks Combat Outpost Keating — located in a valley at the bottom of three steep ridgelines in Nuristan Province, a position that experienced officers had described as militarily indefensible. Eight American soldiers are killed and 22 wounded before air support, including A-10 Warthogs and B-1 bombers, breaks the assault. Staff Sgt. Clint Romesha and Spec. Ty Carter both receive the Medal of Honor for their actions that day. The outpost is abandoned and destroyed two days later.

Kamdesh was a microcosm of the war's strategic incoherence: an outpost established for political-diplomatic reasons (to maintain local relationships and presence) rather than military ones, sited in an impossible defensive position, scheduled for closure, and attacked before the withdrawal could happen. The battle was dramatized in Sebastian Junger's book 'Outpost' (later 'The Outpost' film). It led directly to a reassessment of the isolated outpost strategy and the closure of dozens of similar positions.
