Op GNEISENAU

Operation GNEISENAU was intended to draw Allied reserves south, widen the German salient and link it with the salient at Amiens. On 9 June 1918, the Germans advanced twenty-one divisions nine miles on a 23 mile front along the Matz River against fierce French and American resistance. But the French had intelligence warning of the impending attack and following a surprise counterattack at Compiègne on 11 June halted the German advance. Op GNEISENAU was ended on 12 June at a cost of around 35,000 Allied and 30,000 German casualties
