supply depots with high explosive bombs. Most of the city was engulfed in flames. The smoke rose to 1,500 meters and stretched as far as Feodosiya, 150 kilometers away. Ground fighting: 16–28 June As Hansen poised his corps for the breakthrough against the 95th Rifle Division, 27 Ju 87s of II./StG 77 attacked Maxim Gorky's main battery. The Germans believed the strike had knocked it out as it stopped firing its artillery. The artillery bombardment began on 16 June. In the morning the attack by the reinforced 132nd Division collapsed the line. The Soviet garrison held out in tunnels, capitulating on 20 June. The 22nd and 24th Infantry Divisions advanced from the northeast. They employed their Goliath remote control demolition vehicles with success against the timber bunkers. One exploded prematurely and two were knocked out by a minefield. Two Panzer III control vehicles were knocked out by Soviet anti-tank fire. By 19:30, Forts Maxim Gorky, Molotov, Schishkova, Volga and Siberia were overrun. The 24th Infantry Division in particular made extensive use of its Nebelwerfer rockets. The 95th and 172nd Rifle Divisions had been lost, as well as the majority of the fortified defences. Only the 25th Rifle remained in the line. Petrov rushed up the 138th Naval Brigade with an extra 2,600 men, which was landed on the 12–13 June. It prevented German forces reaching Severnaya Bay that day. The Luftwaffe was also engaged in applying pressure to Soviet naval forces. On 18 June the cruiser Kharkov was severely damaged. Attacks on 19 June by KG 51 destroyed the anti-aircraft platform in Severnaya Bay, allowing air operations to continue unopposed. The lack of anti-aircraft cover made it impossible for the minelayer Komintern to enter the harbour with reinforcements. The lack of supplies resulted in Soviet ammunition and fuel supplies slipping to critical levels on 20 June. The Luftwaffe was experiencing shortages of its own. The daily average of sorties was now reduced by 40 percent. Due to the shortages of bombs, all ordnance had to be dropped individually to minimise wastage. Some experienced crews had to conduct dive-bombing attacks 25–30 times a day. KG 51's Ju 88 crews in particular had felt the strain. The pressure took its toll, and between the 18–23 June, the entire Soviet defence line in the north collapsed. The remnants of the 95th Rifle Division was huddled into a 2 km square portion of coast
