|  The 2nd British Army, to which 83 Group (143 Wing'sparent formation) was allied, was engaged in holding the Maas River            line during the Battle of the Rhineland; its air support units had            the task of doing everything in their power to stop the enemy            moving troops and supplies into the battle area, or retreating from            it.
  Between 1 February and 22 March No. 439 Squadron carried out            106 operations. Of these, 92 were dive bombing attacks on rail            lines or
    bridges (1) . The remaining fourteen were chiefly armed            recces without bombs, with three attacks on V.l sites, and two Army            support jobs to complete the picture. 
     
    (1) The importance of this work in disorganizing the German supply                lines was impressed upon the pilots by two Army officers who                visited the wing. They pointed out that when the troops                overran enemy territory they found some sectors had guns but                no ammunition and others had ammunition but no guns!
