The German 57th Infantry Division suffered about 1,000 casualties; all the 37 mm anti-tank guns in the bridgehead had been destroyed. The German casualties included about 300 prisoners.

The 4th Army offensive on the Somme began at opposite the 51st (Highland) Infantry Division at St Valery-sur-Somme. German infantry moved forward against Saigneville, Mons, Catigny, Pendé, Tilloy and Sallenelle, held by the 7th and 8th battalions, Argyll and Sutherland Highlanders (Argylls), as other troops passed between them, the villages being too far apart for mutual support. Saigneville, Mons, Catigny, Pendé and Tilloy fell late in the afternoon and the 7th Argylls were surrounded at Franleu by troops infiltrating between Mons and Arrest, as they were attacked frontally. The 4th Black Watch were ordered from reserve to relieve Franleu but were stopped by German troops at Feuquières and an Argylls company sent forward was surrounded at the edge of Franleu. By dark, the remnants of the 154th Infantry Brigade had been pushed back to a line from Woincourt to Eu. On the right, the 153rd Infantry Brigade was bombarded by Ju 87 Stuka dive-bombers as well as by mortar and artillery fire.
