Prepare for the defense of the location after you warn Desdemona about Brotherhood of Steel's attack on the H.Q. After a moment, two armored and few unarmored enemies will enter the hideout through the back entrance. You can quickly block it with mines or use the miniature atomic bomb to immediately get rid of all of them. The quest doesn't end at this point.

Get through the corridor to the church, preferably using power armors which you can also take from the fallen enemies - Precipice of War - Major Quests for Railroad faction - Fallout 4 Game Guide & Walkthrough

Walk out through the main entrance to the church and keep going through the corridor while eliminating the brothers on your path (many of them will have armor). The last ones are located inside the church and you can catch them by surprise with any explosives - they are standing close to each other.

Follow Tom and Deacon in order to reclaim the police station

Tom will give you explosives that will come in handy in the next task... - Precipice of War - Major Quests for Railroad faction - Fallout 4 Game Guide & Walkthrough

Talk with Desdemona after eliminating all the attackers. She will give you next objective - going with Tinker Tom to Cambridge Police Station. First meet with Tom and Deacon (it is a good idea to have other companion at that point, this will allow you to attack the station with three allies). Other Brotherhood's paladins will be waiting for you in front of the station, try eliminating them from distance. Then enter the building.

Your objective is to completely clear the location. Luckily, you won't find any powerful enemies here. Once all the targets are down, talk to Tom. He will give you C4. Now use the stairs inside to reach the roof of the building. Enemy transporter is located there. Quickly sit behind the cannon in the vehicle. After a moment the Brotherhood will attack you again. Only after you get rid of all enemies you can speak with Deacon and complete the quest.

Quest rewards: Experience points, equipment set from Deacon (Stimpaks, grenades, ammunition), 500 bottlecaps.
