A human wave attack, also known as a human sea attack,^[1] is an offensive infantry tactic in which an attacker conducts an unprotected frontal assault with densely concentrated infantry formations against the enemy line, intended to overrun and overwhelm the defenders by engaging in melee combat. The name refers to the concept of a coordinated mass of soldiers falling upon an enemy force and sweeping them away with sheer weight and momentum, like an ocean wave breaking on a beach.

Creeping barrage

A creeping barrage (also called a moving barrage^[3]) was a barrage that lifted in small increments, usually 50–100 yards every few minutes, moving forward slowly, keeping pace with the infantry.^[4] British practice evolved to fire at two lines simultaneously. Eventually, three patterns of advancing the barrage developed. In a creeping barrage, the shell-fire moved from one line to the next. In a block barrage two or more lines were fired on simultaneously and then the fire moved as block to the next lines to be engaged. In a rolling barrage, the fire on the line nearest to their own troops moved to the first unengaged line behind then after a set interval the fire on the second line would move in turn to the next one behind that.^[5]

By late 1917, the technique of a creeping barrage had been perfected and could be made to move in complex ways, the barrage wheeling or even combing back and forth, to catch the defenders re-emerging after the barrage had passed but it was still governed by a timetable.^[6] A creeping barrage that was too slow would risk friendly fire on one's advancing troops; too quickly could mean that the enemy would have too much time to emerge from cover to resume defensive positions and attack the exposed advancing troops. After World War I the British developed the "quick barrage", a standard barrage pattern that could be ordered by radio without advance plotting of the fire plan on a map.^[7]
