CREEPING BARRAGE. A military term denoting the system (introduced in 1916) whereby infantry advance and the ar tillery fire are regulated by a time-table, the barrage, or curtain of shells, moving forward a stated number of yards every minute and the infantry following behind it. The limitation of the standing barrage was that the curtain of shells did not move with the troops; and whilst a creeping barrage made short bounds of 5o to too yards, a jumping barrage made longer ones, and was in fact no more than a series of short standing barrages. A rolling barrage only differed from a creeping in that the moving forward of the shell curtain was continuous from opening of fire onwards, no definite bounds of fire being made.
