On August 22, the Japanese 3rd, 8th, and 11th Divisions made an amphibious assault under the cover of naval bombardment and proceeded to land in Chuanshakou (川沙口), Shizilin (獅子林), and Baoshan (寶山), towns on the northeast coast some fifty kilometers (31 miles) away from downtown Shanghai. Japanese landings in northeast Shanghai suburban areas meant that many Chinese troops, who were deployed in Shanghai's urban center, had to be redeployed to the coastal regions to counter the landings. Thus, the front line was lengthened from metropolitan Shanghai along the Huangpu River to the northeast coastal districts. The Chinese offensive in the urban center had ground to a halt, and the fighting in downtown Shanghai essentially became a stalemate with both sides suffering heavy losses and making minimal changes in the front line. The Chinese divisions were able to hold on to Zhabei, Jiangwan, and other downtown positions for three months, until situations in other areas made it strategically impossible to continue defending them.
