Timeline

  1. c. 1541–1545Italian battlefield · LombardyDuring the Italian Wars of the 1540s, engineer units of both attackers and defenders systematically used gabions to build parallel trench breastworks, shelter advancing gun positions, and, combined with earthwork reverse slopes, absorb cannonball kinetic energy, significantly prolonging siege durations.
  2. c. 1546–1550Netherlands and French border · Low CountriesBy 1550, gabions and earthwork systems were combined with star-shaped bastion designs, used for temporary raising of bastion exteriors, sheltering outworks, and filling breastwork sections destroyed by gunfire, becoming standard operating procedure for fortification engineers in the gunpowder age.
