the war strength in regard to German divisions was but a relative term. As General Patch's Seventh Army attacked before daylight on 15 March, the apparent answer on German intentions was quick to come. Only in two places could the resistance be called determined. One was on the left wing, where the 63rd Infantry Division (Maj. Gen. Louis E. Hibbs) sought to bypass Saarbrücken on the east and cut German escape routes from the city. The fact that the 63rd Division early hit the Siegfried Line provided ready explanation for the stanch opposition there. The other was on the extreme right wing where an attached 3rd Algerian Infantry Division (3e Division d'Infanterie d'Algerie) was to clear the expanse of flatland between Hagenau and the Rhine. There an urban area closely backing the Moder River defensive line and flat ground affording superb fields of fire for dug-in automatic weapons accounted in large measure for the more difficult fighting. Elsewhere, local engagements sometimes were vicious and costly but usually were short-lived. Anti-personnel and anti-tank mines abounded. German artillery fire seldom was more than moderate and in most cases could better be classified as light or sporadic. That was attributable in part to a campaign of interdiction for several days preceding the attack by planes of the XII Tactical Air Command (Brig. Gen. Glenn O. Barcus) and by D-day strikes by both the fighter-bombers and the mediums and heavies of the 8th Air Force. The latter hit Siegfried Line fortifications and industrial targets in cities such as Zweibrücken and Kaiserslautern. The weather was beautifully clear, enabling the aircraft to strike at a variety of targets, limited only by range and bomb-carrying capacity. Among the German casualties were the operations officers of two of the three XC Korps divisions. Of the units of the outsized (six divisions) XV Corps, only a regiment of the 45th Infantry Division (Maj. Gen. Robert T. Frederick) faced a water obstacle at the start. That regiment had to cross the Blies River at a site upstream from where the Blies turns northeast to meander up the Kaiserslautern corridor. Yet even before dawn men of the regiment had penetrated the enemy's main line of defense beyond the river. Aided by searchlights, they bypassed strongpoints, leaving them for reserves to take out later. As night came, the 45th Division had driven almost beyond the Blies to match a rate of advance
